EZ-SCSI 4.01 readme

The following information is available in this README file:

OVERVIEW OF APPLICATIONS

If you are a Windows 95 or Windows NT user, the following applications will be installed to your system:

SCSI Explorer

This application gives you three powerful functions:

  • SCSI Power Management
  • SCSI Interrogator
  • SCSI Cache Management

Adaptec Backup (Windows 95 only)

This backup application allows you to backup your system to a hard drive, removable drive, or a SCSI tape drive. A list of supported SCSI tape drives is listed later in this README

NOTE: Adaptec Backup is only shipped with the full version of Adaptec EZ-SCSI. This does not include the 'L' license version (e.g. 4.00L)

Audio CD Player

This innovative Audio CD Player gives you four different modes to listen to CDs:

  • Jukebox CD-Player (optimized for 256 colors)
  • Standard CD-Player
  • Mini CD-Player
  • Micro CD-Player (requires Windows 95 Desktop)

In addition to supporting its own audio database, the Adaptec CD Player automatically supports the Microsoft CD Player database. If you have already typed in your music database, there is no need to re-enter it twice.

Photo CD Viewer

Convert your favorite photos to the Photo CD format to view and edit them on your PC. Use this application to view the 80+ professional quality Photo CD images included with Adaptec EZ-SCSI (CD-ROM version only).

CD Copier

Do you use a CD Recordable drive to distribute custom CDs? Do you ever find the need to make a quick, and easy, duplicate of your CD? If the answer is yes, then the Adaptec CD Copier is for you. Simply place your source CD in a CD-ROM drive and a blank CD-R in your CD Recordable drive. Then run our CD Copier and simply click the "Copy" button. Nothing could be easier.

CD Writer

Have a need to move files from your hard drive to your CD Recordable drive? If so, Adaptec's CD Writer will do exactly that. Ideal for backups, software distribution, multimedia publishing, or whatever else you can think of.

NOTE: CD Writer is only shipped with the full version of Adaptec EZ-SCSI. This does not include the 'L' license version (e.g. 4.00L).

QuickScan

So you have a TWAIN compliant SCSI scanner hooked up to your system and a printer. You have some documentation that you need a quick copy of. Adaptec's QuickScan converts your scanner and printer combination into a photo copy machine.

SCSIBench

SCSIBench allows you to determine the performance capabilities of your peripherals.

Drive Light

Drive Light gives you a visual representation of your SCSI activity. In addition, it also keeps I/O statistics so you can see just how much I/O is occurring to your SCSI devices. View just how much percent of your I/O is reads vs. writes.

16-Bit Applications

If you are a Windows 3.1/3.11 user, many similar 16-bit applications are also available. Please refer to the on-line help available with each application after you install Adaptec EZ-SCSI under Windows 3.1/3.11. Additional information on running with Windows 3.1/3.11 is also provided later in this README.

 

SCSI MINIPORTS

What is a SCSI miniport? A SCSI miniport is a device driver that controls your SCSI host adapter. For example, if you are running Windows 95 with an Adaptec AHA-2940, the miniport driver you are using is named aic78xx.mpd. Windows 95 and NT come with embedded drivers for most of Adaptecs host adapters. For those host adapter drivers not yet embedded or that have changed, we've included them on the "Adaptec EZ-SCSI Setup and Drivers Installation Disk" CD-ROM version of EZ-SCSI only).

For other SCSI host adapters not included on our floppy, additional miniport drivers can be found at one of the following locations:

Windows 95

  • Windows 95 CD (in \DRIVERS\STORAGE directory)
  • Microsoft Network:
    Categories\Computers\ and Software\Software\Microsoft\Windows 95
  • Internet World Wide Web:

  • Microsoft Download Service (MSDL): call 206-936-6735
  • Compuserve: GO MSL
  • GEnie: Go to Microsoft Roundtable
  • Call Microsoft Product Support Services
  • If you have an Adaptec SCSI Host Adapter, you can download the latest Windows 95 miniports from one of our on-line services. See "CONTACTING ADAPTEC"below for additional information.

NOTE: See on-line help in \Drivers directory on the Windows 95 CD for details

Windows NT

If you have an Adaptec SCSI Host Adapter, you can download the latest Windows NT miniports from one of our on-line services. See "CONTACTING ADAPTEC"below for additional information. For other host adapters, contact your host adapter vendor

Additional Information for the AHA-2920 miniports

The following non-standard command line options are available for AHA-2920 miniports in Windows 95 (FD16_700.MPD) and Windows NT versions 3.51 and up (FD16_700.SYS):

AdapterScansUp

This option forces the miniport to scan the SCSI devices in an ascending (SCSI ID) order. This is used for compatibility with previous AHA-2920 installations in which SCSI devices were scanned in an ascending order to prevent drive-letter reversal.

DisableSynchronousTransfers=d+

Where "d+" represents one or more decimal digits, each indicating a single SCSI target ID. This option disables synchronous transfers (SDTR negotiation) on the indicated SCSI target IDs. For example:

DisableSynchronousTransfers=245

turns off Synchronous Data Transfer Negotiations (and thus synchronous transfers) on SCSI target IDs 2, 4, and 5.

Adding options to Windows NT

  1. Start the registry editor by typing REGEDT32 at the MS-DOS command prompt (or from the Program Manager's "File"-->"Run" command). Open \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services
  2. Open the name of the particular miniport ("Fd16_700")
  3. Create a key named "Parameters" using the "Edit"-->"Add Key" command.
  4. Open "Parameters" and create a key named "Device"
  5. Open "Device"

    A).To disable synchronous transfers, perform the "Edit"-->"Add Value" command with the following information:

    Value Name:    DisableSynchronousTransfers
    Data Type:       REG_DWORD
    Value:              non-zero value to disable synchronous transfer

    B).To disable disconnects, perform the "Edit"-->"Add Value" command with the following information:

    Value Name:    DisableDisconnects
    Data Type:       REG_DWORD
    Value:              non-zero value to disable disconnects

    C).To set the maximum LUN to be scanned, perform the "Edit"-->"Add Value" command with the following information:

    Value Name:    MaximumLogicalUnit
    Data Type:       REG_DWORD
    Value:              maximum LUN to scan up to (if one is entered,                        only LUN 0 will be scanned)

    D). To use the DisableSynchronousTransfers on a device-specific basis, or to use the AdapterScansUp parameter, perform the "Edit"-->"Add Value" command with the following information:

    Value Name:    DriverParameter
    Data Type:       REG_SZ
    Value:              parameters as described separated by semicolons(;)

  6. Exit the registry Editor and reboot the system

Adding options to Windows 95

  1. To add these options to the Windows 95 miniport driver, click the right mouse button once on the "My Computer" icon and select "Properties". This will bring up the System Properties dialog box.
  2. Select the "Device Manager" tab.
  3. Open the "SCSI Controllers" sub-tree, and select the "Future Domain PCI SCSI Host Adapter" branch.
  4. Click on the "Properties" button.
  5. Select the "Settings" tab.
  6. Type the desired options in the "Adapter Settings" edit box, separating each option with a semi-colon (;).

You can also set other settings such as Disconnect Disable through the Settings Tab of the particular device whose properties you wish to alter. To disable the option, un-check the appropriate box in the Options group. To enable the option, check the appropriate box in the Options group.

 

HARD DISK SUPPORT

Windows 95 includes built-in support for SCSI hard drives. If you attach a new, unformatted, drive to your SCSI host adapter, you will need to partition and format the media before you can use it. You can follow these steps:

Windows 95

  1. Run Device Manager. You can do this by moving the mouse pointer over "My Computer," clicking the right mouse button, and selecting the "Properties" menu option.
  2. Select the "Device Manager" option.
  3. Expand the "Disk drives" tree to view your SCSI hard drives.
  4. Double-click on your newly added hard drive.
  5. Select the "Settings" option.
  6. If the "Int 13 unit" option is not turned on, then turn it on and select OK. Reboot your system.
  7. Open up a DOS session (MS-DOS prompt).
  8. Run FDISK to partition your new drive as you desire.
  9. Reboot your operating system.
  10. When Windows 95 comes back up, double-click on "My Computer."
  11. Move the mouse pointer over your new drive letter(s), click the right mouse button, and then select the "Format..." option. Follow the instructions to format your media.

NOTE:Under many configurations, steps 1-6 are not required as Windows 95 may have already marked your new disk drive as an "Int 13 unit." We still recommend that you take these steps to ensure that your system is properly configured.

Windows NT

Windows NT includes built-in support for SCSI hard drives. If you attach a new, unformatted, drive to your SCSI host adapter, you will need to partition and format the media before you can use it. You can format your new drive, under NT, by running the "Disk Administrator" utility that ships with the operating system.

Windows 3.1/3.11 and DOS

DOS and Windows 3.1x include built-in support for SCSI hard drives if your new drive is under BIOS control (e.g. you booted from it). Please refer to your host adapter documentation to learn more about whether or not your SCSI host adapter includes an on-board ROM BIOS. In this case, you can follow these steps:

  1. Boot to DOS.
  2. Run FDISK to partition your new drive as you desire.
  3. Reboot your operating system.
  4. Run FORMAT on your newly created drive letter(s)

If your new SCSI hard drive is not under BIOS control, you can follow these steps:

  1. If running Windows 3.1x, install Adaptec EZ-SCSI for Windows 3.1x. Insert the Adaptec EZ-SCSI Setup Disk and run SETUP.EXE
  2. If running DOS, install Adaptec EZ-SCSI for DOS. Insert the Adaptec EZ-SCSI Setup Disk. Run INSTALL.BAT
  3. After installing either Adaptec EZ-SCSI for DOS/Windows, reboot your system.
  4. If you are running DOS, run AFDISK.EXE which is located in your Adaptec EZ-SCSI subdirectory (e.g. C:\SCSI). If you are running Windows, you can use WINPART.EXE which is a Windows 3.1x partitioning utility.
  5. Partition your new media as you desire.
  6. Reboot your operating system.
  7. At this point, your new drive is under ASPIDISK.SYS control(Adaptec's disk driver for DOS).
  8. Although optional, we recommend that you run DOS FORMAT on your new drive letter(s) so that the drive can be scanned for defects.

REMOVABLE MEDIA SUPPORT

Windows 95

There are a number of ways to prepare your removable media for use under Windows 95.Windows 95, by default, will allocate one drive letter for your removable media device. You can see the icon by double-clicking on "My Computer" and seeing the "Removable Disk" text just below the drive's icon. If you wish to treat your removable media as one large floppy, simply insert the media into the drive and double-click on the icon. Windows 95 will automatically detect that the media is unformatted and ask you if you would like to format the media.

Windows 95 also allows you to use partitioned removable media. For example, if you have a 1 GByte removable cartridge, you might want to partition the media into two 512 MByte partitions. To create a partitioned removable media, you can follow these steps.

  1. Run Device Manager. You can do this by moving the mouse pointer over "My Computer," clicking the right mouse button, and selecting the "Properties" menu option.
  2. Select the "Device Manager" option.
  3. Expand the "Disk drives" tree to view your SCSI removable hard drive.
  4. Double-click on your newly added removable hard drive.
  5. Select the "Settings" option.
  6. If the "Int 13 unit" option is not turned on, then turn it on and select OK. The "Removable" option should also be set. Reboot your system.
  7. Open up a DOS session (MS-DOS prompt).
  8. Run FDISK to partition your removable media as you desire.
  9. Reboot your operating system.
  10. If you want to reserve multiple drive letters for your removable media drive (e.g. multiple partitions), follow the next steps, otherwise, skip to step #17
  11. Run Device Manager. You can do this by moving the mouse pointer over "My Computer," clicking the right mouse button, and selecting the "Properties" menu option.
  12. Select the "Device Manager" option.
  13. Expand the "Disk drives" tree to view your SCSI removable hard drive.
  14. Double-click on your newly added removable hard drive.
  15. Select the "Settings" option.
  16. In the "Reserved Drive Letters" area, you can select the starting and ending drive letters for your removable media device. Save settings and reboot your system.
  17. When Windows 95 comes back up, double-click on "My Computer."
  18. Move the mouse pointer over your new drive, click the right mouse button, and then select the "Format..." option.
  19. Follow the instructions to format your media.

NOTE: Under many configurations, steps 1-6 are not required as Windows 95 may have already marked your new disk drive as an "Int 13 unit." We still recommend that you take these steps to ensure that your system is properly configured.

Below is additional information you may find useful:

We recommend that you boot Windows 95 without a DOS removable media device driver (e.g. ASPIDISK.SYS). You can comment out such entries from your CONFIG.SYS and then reboot. We have seen Windows 95 incorrectly create two drive letters for the same device when a DOS removable media driver is resident. In addition, we have seen some configurations where Windows 95 wouldn't allow us to set the starting and ending drive letters when a DOS removable media device driver is resident.

Windows NT

Please consult your Windows NT documentation on using removable media with Windows NT.

Windows 3.1/3.11 and DOS

To prepare your removable media for use under Windows 3.1/3.11 and DOS, you can follow these steps.

  1. If running Windows 3.1x, install Adaptec EZ-SCSI for Windows 3.1x. Insert the Adaptec EZ-SCSI Setup Disk. Run SETUP.EXE
  2. If running DOS, install Adaptec EZ-SCSI for DOS. Insert the Adaptec EZ-SCSI Setup Disk. Run INSTALL.BAT
  3. After installing either Adaptec EZ-SCSI for DOS/Windows, reboot your system.
  4. If you are running DOS, run AFDISK.EXE which is located in your Adaptec EZ-SCSI subdirectory (e.g. C:\SCSI). If you are running Windows, you can use WINPART.EXE which is a Windows 3.1x partitioning utility.
  5. Partition your new media as you desire.
  6. Reboot your operating system.
  7. At this point, your new drive is under ASPIDISK.SYS control (Adaptec's disk driver for DOS).
  8. Although optional, we recommend that you run DOS FORMAT on your new drive letter(s) so that the drive can be scanned for defects.

Below is additional information you may find useful:

  • Adaptec EZ-SCSI supports both 512 byte/sector media and 1024 byte/ sector media.
  • If you would like to reserve multiple drive letters for your removable media, you can use the /r command line switch. For example, if you would like ASPIDISK.SYS to reserve two drive letters for your removable media, you would have the following in your CONFIG.SYS:

    device=c:\scsi\aspidisk.sys /d /r2

  • Support for the Panasonic PD drive is also included. Note that you should leave this device jumpered in its default two LUN mode.
CD-ROM SUPPORT

Windows 95

Windows 95 includes built-in support for SCSI-2 CD-ROM drives and some SCSI-1 devices. If your host adapter already has its miniport loaded, 95 will automatically detect and support your SCSI CD-ROM drive.

We recommend that you boot Windows 95 without a DOS CD-ROM device driver (e.g. ASPICD.SYS). You can comment out such entries from your CONFIG.SYS and then reboot. We have seen Windows 95 incorrectly create two drive letters for the same device when a DOS CD-ROM driver is resident.

Windows NT

Please consult your Windows NT documentation on using CD-ROM drives with Windows NT.

Windows 3.1/3.11 and DOS

Adaptec's CD-ROM driver for DOS/Windows, ASPICD.SYS, has been written to support any SCSI-2 CD-ROM drive and most SCSI-1 CD-ROM drives. Simply run Adaptec EZ-SCSI and the correct additions will be made to your CONFIG.SYS and AUTOEXEC.BAT.

Adaptec EZ-SCSI has been tested with CD-ROM drives from the following vendors:

AIWACompaqChinonDenonGoldstar
HitachiIBMLMSMatsushitaNEC
PanasonicNakamichiPhilipsPioneerPlasmon Data
PlextorRicohSanyoSonyTEAC
TexelToshibaYamaha

Below is additional information you may find useful:

The following drives do not directly support Photo CD:

ChinonCDS 431
DenonDRD 235
LMS (Phillips)CM 214
NECCDR 72
NEC*CDR 74
NEC*CDR 84

*NOTE: 74-1 and 84-1 do support single-session Photo CD

By adding /XAEMUL to the ASPICD.SYS command line, in your CONFIG.SYS, we will emulate support for single-session Photo CD on these drives.

The following drives do not support parity:

NEC CDR 38
NEC CDR 55
NEC CDR 72
NEC CDR 73
NEC CDR 74 (NOTE: 74-1 and 84-1 do support SCSI parity)
NEC CDR 84
NEC CDR 210(NOTE: 210P does support parity)

Please consult your host adapter documentation on how to disable parity support on your SCSI host adapter.

The following jukebox CD-ROM drives are fully supported:

NakamichiMBR-7
PioneerDRM 600
PioneerDRM 604X
PioneerDRM 624X

A drive letter will be assigned for each CD.

Some older SCSI CD-ROM drives do not support synchronous negotiation properly. If you encounter problems using your CD-ROM drive, try disabling synchronous negotiation. Please refer to your host adapter documentation on how to do this.

In rare circumstances, you may encounter problems with Windows 3.x and DOS reading your CD-ROM drive.For example, you change the contents of the CD-ROM drive, but when you run DIR, the contents of the previous CD is displayed instead of the new CD's. One solution is to add the /NOLUN switch to the aspicd.sys line in config.sys. We have only seen this problem with the Sony 55s - an older double speed CD-ROM drive. By adding the /NOLUN switch, you will however loose support for any CD Changers or PD drives that you also have connected to your PC.

 

TAPE DRIVE SUPPORT

Windows 95

NOTE: Adaptec Backup is only shipped with the full version of Adaptec EZ-SCSI. This does not include the 'L' license version (e.g. 4.00L).

Adaptec EZ-SCSI includes a full-featured Backup application designed for Windows 95. Adaptec Backup can backup to a SCSI tape drive, and if you do not have a SCSI tape drive attached, it can also backup to your hard drive or to a removable hard drive. Adaptec EZ-SCSI has been tested for compatibility with the following SCSI tape drives:

(1) Adaptec Backup does not support tape linking on these SCSI tape drives. Tape linking allows you to continue a backup across two or more tapes.

(2) On this tape drive, restores and compares will be slow to start. This does not affect backups.

(3) On this tape drive, only a single Backup set is supported.

Please note the following:

  • Unerase and Rename Tape are not supported by SCSI tape drives so these menu options will be grayed out when running Adaptec Backup.
  • Doing a Secure Erase on a DAT drive will usually take several hours to complete. During this process, you will not be able to exit the application until the Secure Erase is complete.
  • If you are using a DAT tape that was previously formatted by a different tape backup application, Adaptec Backup may take up to 5 minutes before it can initialize the tape. You should format the tape with Adaptec Backup once the initialization is complete.
  • If you are encountering problems backing up to a hard disk, network drive,or removable media drive - make sure that there is no SCSI tape drive attached to your system. Backup to a hard disk, network drive, or removable media drive is only supported when there is no SCSI tape drive attached.
  • Adaptec backup does not support backing up a floppy to a tapedrive.

Windows NT

Adaptec EZ-SCSI does not include a tape backup package for Windows NT. Please consult your Windows NT documentation for additional informationon the SCSI tape backup application that ships with the operating system. In addition, if you have the CD-ROM version of Adaptec EZ-SCSI, you can view Adaptec's 3rd party directory for a list of companies who provide SCSI tape backup support. Simply double click on the file 96dir.hlp in the \ACAP directory of your Adaptec EZ-SCSI CD-ROM.

Windows 3.1/3.11 and DOS

Adaptec EZ-SCSI does not include a tape backup package for DOS or Windows 3.1x. If you have the CD-ROM version of Adaptec EZ-SCSI, you can view Adaptec's 3rd party catalog for a list of companies who provide SCSI tape backup support. Simply double click on the file 96dir.hlp in the \ACAP directory of your Adaptec EZ-SCSI CD-ROM.

 

CD RECORDABLE SUPPORT

Windows 95

NOTE: CD Writer is only shipped with the full version of Adaptec EZ-SCSI. This does not include the 'L' license version (e.g. 4.00L).

When using a CD Recordable drive, you need an application to write to the CD. It is also desirable to have a device driver that assigns a drive letter to the CD Recordable so that you can also read files from the drive in the standard way. If your CD Recordable supports audio, this would also allow you to play audio CDs.

Most CD Recordable devices today report themselves as a Write Once Read Many (WORM) device. Some of the newer CD Recordable devices report themselves as a standard CD-ROM drive. If your device is of the latter type, Windows 95 should automatically assign a drive letter to your drive. If your device reports itself as a WORM device, then you will need to load our real mode CD-ROM driver and Microsoft's CD-ROM extensions (MSCDEX.EXE). The simplest way to load the real mode drivers is to exit Windows 95 back to DOS and run Adaptec EZ-SCSI for DOS discussed earlier). Once these changes are made, you can reboot back into Windows 95 and have a drive letter assigned to your CD Recordable drive. Windows 95 will mark your CD Recordable device as "Unknown." This is normal.

In addition to reading from a device, you will need the ability to create a CD-ROM. Adaptec EZ-SCSI includes two applications that allow you to fully utilize your CD Recordable drive:

CD Writer     Allows you to copy files from your hard drive to your CD Recordable drive.

CD Copier    Allows you to backup CDs from your source SCSI-2 CD-ROM drive to one of the destination CD Recordable devices listed below. You can backup audio CDs and data mode 1 CDs (most CDs), but not photo CDs or CD-i CDs.

(1) Audio copy only works on this CD Recorder if the source CD can read audio at 2x or greater such as a Sony 561.

(2) With the HP C4324/C4325 (4020i) and the Philips CDD2000, you will need v1.20 or later of their firmware. You can use the SCSI Explorer to determine the revision level of your unit.

(3) "After a successful simulated copy do a real copy" does not work on this drive. You should do a simulated copy by leaving the "Simulate Only" checkbox checked. If this is successful, uncheck the "Simulate Only" checkbox and run copy again.

WARNING: If your CD-Recordable drive is one of the ones that report themselves as a standard CD-ROM drive, you will need to turn off Auto Insert Notification for it while recording discs. To do this:

  1. Run Device Manager. You can do this by moving the mouse pointer over "My Computer," clicking the right mouse button, and selecting the "Properties" menu option.
  2. Select the "Device Manager" option.
  3. Expand the "CDROM" tree to view your CDROM drives.
  4. Double-click on your CD-Recorder.
  5. Select the "Settings" option.
  6. Remove the check box from the "Auto insert notification" field.
  7. Reboot your system.

Because CD-ROM drives vary in how well they support the SCSI specification, we have created a table below which contains a list of the CD-ROM players that we have successfully made copies of CDs from, and notes on any problems we encountered. If your drive is not on this List, but is a derivative of one of these drives, or is fully SCSI-2 compliant, you should be able to use it as a source to backup data CDs from. We also note in this table those drives which you can use as a source to backup an audio CD. Reading of audio tracks is not a SCSI-2 defined function, and is implemented differently by those newer drives that actually support this feature.

(2) This drive sometimes has problems reading the last blocks of a CD made by a CD Recorder (e.g. a copy of a copy), and has resulted in CDs being ruined. If a SCSI command takes too Long, Windows 95 and Windows NT will reset the SCSI bus and SCSI devices, thereby halting the writing process on the CD Recorder resulting in a ruined disc.

(3) In our testing of this device, there is a background hiss when copying audio CDs.

(4) We have seen some read positioning errors on this device causing audio copying to sometimes fail.

Additional information on CD-ROM readers:

  • We do not support copying CDs from a Pioneer DRM-604X CD-ROM drive.
  • The Adaptec CD Copier runs best if you do not have a dirty or scratched source CD as timeouts can occur given this condition.

If you are familiar with CD-Recorder technology, you already know that once you start writing a track, you cannot stop until that track has been completely written. The write process must be uninterrupted otherwise theblank CD will be ruined.

To reduce the need for a large amount of free space on your hard disk, Adaptec CD Copier does on the fly recording (i.e. it reads and writes directly to and from the CD player and recorder without hard disk buffering). It is therefore very important that we can read data from your CD player at least as fast as we can write to your CD-Recorder. By default, we determine the speed of your CD player, and then set the CD Recorder speed to be slower than this. You can view the speed that we set the CD-Recorder to in the text shown in the status window "Now copying CD at 2x ...". If you feel the speed we choose for the CD-Recorder is too conservative, you can set it to a higher one using the Advanced tab. Before you choose a faster speed, please make sure that the speed you pick is not faster than the speed of the CD player. To check for this with data CDs, place a data CD like your Adaptec EZ-SCSI CD into your CD player, and run Adaptec SCSIBench. Choose your player and start a 64K sequential read benchmark on it. To set your recorder to 2x (i.e. double speed) the transfer rate as displayed by Adaptec SCSIBench on the right hand side should be at least 300 KB/sec. We do not provide you with a method to test the speed when reading an audio CD. Most of the drives that we have tested, except for Sony, read audio at 1x. Therefore you will not be able to make an audio backup with any CD Recorder that cannot be set to 1x.

Most users will place their CD-ROM drive and CD-Recorder on the same host adapter. That is how we test it here at Adaptec. In order to achieve the performance that we desire, it is important that your CD-ROM drive NOT have excessive SCSI bus utilization. Fortunately, most SCSI CD-ROM drives get on and off the bus very quickly and support SCSI disconnect. Unfortunately, a few do not and this can cause buffer underrun conditions.

How do you test for this? First off, make sure that you have SCSI disconnection enabled at all times. Windows 95 allows you to enable or disable it from the Device Manager. Please leave it enabled. Also, many SCSI host adapters allow you to change the settings via their configuration software (e.g. SCSISelect). These will ship with disconnection enabled by default. If you disabled disconnection, please turn disconnect back on before trying this software. If you have a SCSI disk drive also hooked up to the same host adapter as the CD-ROM drive and CD-Recorder drive, you're ready to run our test. Run Adaptec SCSIBench and do a 64K sequential read benchmark of your disk drive only. You'll see a number appear, typically between 1 MByte/sec and 7 Mbytes/sec. Now, insert a data CD into your CD-ROM drive. Add it to your benchmark by clicking on its device name. At this point, both devices are part of the benchmark. If you have a 3x CD-ROM drive, you will see that your CD-ROM drive is sustaining about 450 Kbytes/sec. If you see that your disk drive's throughput has dropped dramatically down to about the same value (e.g. 450), then you probably have a CD-ROM drive that has excessive bus utilization. If you encounter this, you may need to set our CD Copier software for single speed copies (e.g. 1x). We do not see this with many CD-ROM drives.

Windows NT

Most CD Recordable devices today report themselves as a Write Once Read Many (WORM) device. Some of the newer CD Recordable devices report themselves as a standard CD-ROM drive. If your device is of the latter type, Windows NT should automatically assign a drive letter to your drive. If your device reports itself as a WORM device, then you will not be able to have a drive letter assigned to your drive.

Adaptec CD Writer and Adaptec CD Copier are both supported under NT.See the discussion under Windows 95 above for additional details.

Windows 3.1/3.11 and DOS

Adaptec EZ-SCSI for Windows 3.1/3.11 and DOS does not include software to allow you to write your own CDs. Adaptec's CD-ROM driver, ASPICD.SYS, does allow you to assign a drive letter to your CD Recordable drive. Third party applications, such as Incat's Easy CD Pro, allow you to master CDs under Windows 3.1/3.11.

Most scanners support the ASPI interface. Contact your scanner vendor to determine if their scanner and software support ASPI.
 

WINDOWS 95/NT GENERAL TROUBLESHOOTING

ASPI Layer

There is a known problem with the Service Pack 4 release of Windows NT 3.51 which prevents Adaptec EZ-SCSI from automatically updating the ASPI layer. The new versions of the ASPI files will be copied to your system during EZ-SCSI installation, but they will have incorrect filenames. If you are running under Windows NT 3.51 Service Pack 4 while installing Adaptec EZ-SCSI and want to update your system to use the new ASPI layer, you must rename these files to their correct filenames as listed below:
Incorrect FilenameCorrect FilenameLocation on System
WINASPI.ADPWINASPI.DLLC:\WINNT\SYSTEM\
WOWPOST.ADPWOWPOST.EXEC:\WINNT\SYSTEM\
WNASPI32.ADPWNASPI32.DLLC:\WINNT\SYSTEM32\
ASPI32.ADPASPI32.SYSC:\WINNT\SYSTEM32\DRIVERS\

Once you have completed renaming these files reboot your system in order for the new ASPI layer to take effect.

Adaptec EZ-SCSI for Windows 95 requires that your miniport drivers (discussed earlier) are properly installed. You can do this by moving the mouse pointer over "My Computer," clicking the right mouse button, and selecting the "Properties" menu option. Find your SCSI host adapter(s), double-click on it, and then you can determine whether or not your miniport driver is properly installed.

The Adaptec EZ-SCSI application, SCSI Explorer, displays a tree-view list of your SCSI host adapter(s) and all devices connected to it. The order which SCSI Explorer displays your SCSI host adapters may not be in the order you think it should be in.

For example:

You may have an Adaptec AHA-2940 PCI SCSI host adapter and an AHA-1542CP ISA SCSI host adapter in your system, and you are booting from the AHA-2940. The AHA-2940 is considered to be host adapter #0 while the AHA-1542CP is considered to be host adapter #1. The SCSI Explorer may display the AHA-1542CP first in the tree-view list followed by the AHA-2940. This ordering issue is the result of the manner in which the Adaptec miniports scan for SCSI host adapters. Adaptec SCSI Explorer will continue to work just fine.

The Adaptec SCSI Interrogator, part of the SCSI Explorer, allows you to lock, unlock, or eject media from a removable media device. Some SCSI devices do not support these commands.

Under Windows NT, Adaptec SCSI Power Management and Drive Light do not support striped hard drives.

Windows NT, Adaptec Drive Light does not monitor ASPI calls. For example, the icons in Drive Light will not flash when running Adaptec SCSIBench. This is not a limitation if running under Windows 95.

Under Windows NT, SCSI tape drives will not appear under Drive Light unless you first load the SCSI tape driver that ships with Windows NT. There are two steps you must do:

  1. Install the tape driver. To install the tape driver, go to Windows NT Setup and choose "Options," choose "Add/Remove Tape Devices," choose "Add," select the appropriate tape drive model, and choose "Install."
  2. Reboot your system.

When running Drive Light under Windows 95, you may notice that we flash your CD-ROM drive every few seconds, even though your CD-ROM drive's LED isn't flashing. This is correct behavior. Although the CD-ROM drive's LED doesn't flash, Windows 95 is checking the drive every few seconds to see if a media change has occurred.

Adaptec EZ-SCSI applications (e.g. SCSI Explorer) do not support multiple LUNs. If you have a multi-LUN device, you will only see LUN #0.

If you are playing an Audio CD, and you try to access the CD-ROM drive through an ASPI application (e.g. SCSI Explorer), the audio may stop playing in order to service your I/O request. This is normal behavior.

Adaptec SCSIBench does not support benchmarking the Pioneer DR-124X CD-ROM drive.

If you are running Adaptec SCSIBench under Windows 95, and it does not work with 64K transfers, but works with any other transfer size, you'll need to upgrade your miniport driver. See the README.TXT file on the Adaptec EZ-SCSI Setup Disk (CD-ROM version only) for information on newer SCSI miniport drivers.

We have seen one system running Windows 95, with a number of 16-bit Windows applications resident, generate a DDE error when the Adaptec EZ-SCSI installation attempts to add icons to your "Start" menu. If you encounter this, please close all resident applications before installing Adaptec EZ-SCSI.

When using ASPI under Windows 95, the ASPI layer will report your SCSI host adapter as SCSI ID #7, even if you've relocated it to a different ID. We recommend that you leave your SCSI host adapter at the factory default setting of SCSI ID #7.

We have found that the Philips CDD-521 and CDD-522 CD Recordable drives not properly handle synchronous negotiation. This can cause the device to not get recognized, or get incorrectly recognized, by the operating system. If you are experiencing this problem, how you solve it depends on the SCSI host adapter you are using and whether you're running Windows 95 or Windows NT.

For Windows 95, Adaptec EZ-SCSI will automatically disable synchronous negotiation for these devices on all of the host adapters except 2920. Please see the 2920 section under Miniports on how to disable synchronous negotiation. If problems still persist, and if your host adapter allows you to disable synchronous negotiation (e.g.SCSISelect), use your host adapter application to disable synchronous negotiation.

For Windows NT, it's a little more involved. If you have a 2920 please see the 2920 section under Miniports on how to disable synchronous negotiation. If the operating system does not correctly detect the device, and if your host adapter allows you to disable synchronous negotiation (e.g. SCSISelect), use your host adapter application to disable synchronous negotiation. If you have a 2920 please see the 2920 section under Miniports on how to disable synchronous negotiation. If your host adapter doesn't have such an application, you can follow these steps to disable synchronous mode for your entire host adapter. There is no per device control. Run REGEDT32.EXE and:

  1. Open \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services
  2. Open the name of the particular miniport
  3. Create a key named Parameters
  4. Open Parameters and create a key named Device
  5. Open Device
  6. Add Value with the following information:
    Value Name: DisableSynchronousTransfers
    Data Type: REG_DWORD
    Value: 1

32-BIT SUPPORT FOR WINDOWS 3.1/3.11

Adaptec EZ-SCSI includes 32-Bit Disk Access support for Windows 3.1, Windows 3.11, and

Windows for Workgroups 3.11. To enable this support, simply run the "32-Bit Disk Access" utility (FASTSCSI.EXE), and follow the instructions. Please note the following:

Our 32-Bit Disk Access device drivers only support Adaptec's busmastering line of SCSI host adapters and Adaptec's AIC-6360/6370 based SCSI host adapters. These host adapters use the following ASPI managers:

ASPI2DOS.SYS
ASPI4DOS.SYS
ASPI7DOS.SYS
ASPI8DOS.SYS
ASPIEDOS.SYS

If your host adapter does not use one of these ASPI managers, our 32-Bit Disk Access utility will still allow you to enable or disable SCSI write caching.

If you are running Windows for Workgroups 3.11, and you are not able to get 32-Bit File Access to work properly, the following comes from Microsoft's Windows for Workgroups resource kit:

"32-bit File Access will not enable on a drive on which there are open files during the initialization process of 32-bit File Access. Because of this, 32-bit file access cannot be enabled through the Control Panel Virtual Memory dialog when using a temporary swap file. The temporary swap file is opened before 32-bit File Access initializes and 32-bit File Access will not be able to enable on the drive where the temporary swap file is located. There normally should not be any open files at the time when 32-bit File Access is initializing. If there are open files, they are probably the result of some real mode TSR or a 3rd-party VxD."

When 32-Bit Disk Access is enabled, you need to have the latest WINASPI.DLL file in your Windows' SYSTEM subdirectory. If an older revision is being used, you will experience protection faults when running "ASPI for Windows" applications. EZ-SCSI 3.11 (and later) will automatically install the correct WINASPI.DLL file. There are, however, a few older packages that install the older WINASPI.DLL file. If you are experiencing protection faults, while running "ASPI for Windows" applications, you should check the date of WINASPI.DLL in your Windows' SYSTEM subdirectory. If it is dated 1995 or later, you have the correct file.

32-Bit Disk Access, in general, does not significantly improve performance under Windows 3.1 or Windows 3.11. To get optimal disk performance, you should use Windows for Workgroups 3.11 which, in addition to 32-Bit Disk Access, includes support for 32-Bit File Access. We are seeing the larger performance gains by enabling 32-Bit Disk Access, 32-Bit File Access, and SCSI write caching.

Our 32-Bit Disk Access driver cannot be used if you are also using our SCSI Power Management driver. If you attempt to load both drivers, an appropriate error message will appear when you run Windows. If you encounter this message, and if you prefer 32-Bit Disk Access over SCSI Power Management, simply run Adaptec's 32-Bit Disk Access utility and select the "Install" option. It will detect the conflict and remove the SCSI power management device driver.

32-Bit Disk Access only supports drives under BIOS control (INT 13h drives). This does NOT include drives under the control of ASPIDISK.SYS. Most of our SCSI host adapters allow you to have up to 8 SCSI drives under BIOS control.

There is a known problem in Windows 3.1 and Windows 3.11 (does not affect Windows for Workgroups 3.11) in that its 32-Bit Disk Access solution only supports up to two hard drives. For example, if you have three hard drives under BIOS control, only the first two would be under 32-Bit Disk Access. If you encounter this situation, you can upgrade to Windows for Workgroups 3.11 which does not exhibit this limitation.

Adaptec's 32-Bit Disk Access utility provides an uninstall option that will remove our 32-Bit device drivers. If you would like to manually remove the drivers, remove the following entries from the [386Enh] section of your SYSTEM.INI file:

device=fastscsi.386 device=aha1540.386
device=aha1740.386
device=aic7770.386
device=aic7870.386
device=aic6x60.386

(NOTE: Not all of these drivers will be present in your SYSTEM.INI file. Depends on what type of host adapter you have.)

Enabling SCSI write caching can improve the overall performance of your system. Many SCSI hard drives ship factory default with SCSI write caching disabled. Our 32-Bit Disk Access utility will allow you to enable or disable SCSI write caching on a per device basis. We have found a few older drives causing system hangs, under intense disk I/O, when write caching is enabled. In the unlikely event that you encounter this situation, you can disable SCSI write caching at any time by running our 32-Bit Disk Access utility.

On some systems, when you enable 32-Bit Disk Access, Windows' Control Panel incorrectly loads the IDE 32-Bit Disk Access driver even if you only have SCSI disk drives. This will typically result in an error message, while loading Windows, similar to the following:

"The Microsoft Windows 32-bit disk driver (WDCTRL) cannot be loaded on this computer because of interrupt conflicts."

If you encounter this, simply remove the line "device=*wdctrl" from the [386Enh] section of your SYSTEM.INI file. Another option is to run our 32-Bit Disk Access utility. It will detect that your configuration is incorrectly loading the IDE device driver and ask if you would like us to remove it.

For the technical user: If you select to turn on SCSI write caching, we will also turn on the AWRE (Automatic Write Reallocation Enabled) bit in the Read/Write Error Recovery Page. If you select to turn off SCSI write caching, the AWRE bit is set back to the factory default setting (some drives ship factory default with AWRE set).

If you have an AVA-2825 or AHA-1520A/1522A, with BIOS support for floptical drives enabled, and you have a floptical drive connected to your system, 32-Bit Disk Access is not supported under Windows 3.1/3.11.

 

DOS ASPI MANAGERS

Adaptec EZ-SCSI includes a number of ASPI managers for Adaptec's family of SCSI host adapters. Below is additional information on some of Adaptec's ASPI managers.

ASPI2DOS.SYS

ASPI2DOS.SYS is the Adaptec ASPI manager for AIC-6260/6360/6370 based SCSI host adapters. Adaptec EZ-SCSI automatically detects which host adapter you have installed, which ASPI manager needs to be loaded, and what the correct command line switches are.

If you are using an Adaptec APA-1425/50/50A/60/60A SlimSCSI, make sure you have PCMCIA Card and Socket Services installed BEFORE running Adaptec EZ-SCSI.

If you have an IBM ThinkPad 360Cs or an IBM ThinkPad 755, and are the Adaptec APA-1425/50/50A/60/60A SlimSCSI, you need to move the following line to the last line inside your CONFIG.SYS file:

DEVICE=C:\EZPLY\$ICPMDOS.SYS

Note: If the directory for EZ-Play is different than the default, use that directory instead. The above line uses the standard directory as an example.

If you have an APA-1425/50/50A/60/60A (SlimSCSI) in your system and are installing ASPI2DOS.SYS manually, you will need to add the following command line switch to ASPI2DOS.SYS in your CONFIG.SYS file:

DEVICE = C:\SCSI\ASPI2DOS.SYS /D /PCMCIA /Z

If you cannot suspend/resume properly on an AcerNote 735c, with an APA-1425/50/50A/60/60A (SlimSCSI), you're probably experiencing an I/O conflict between the APA-1425/50/50A/60/60A and your laptop. The AcerNote uses port 35F for video control. You'll need to manually exclude this I/O port. With SystemSoft Card and Socket Services, you can do this by editing the CSALLOC.INI file and adding the line:

ioexclude=35F

If you are using the Gateway 2000 Colorbook laptop with an Adaptec APA-1425/50/50A/60/60A (SlimSCSI), ASPI2DOS.SYS may fail during driver installation. If you encounter this problem, you will need to run the CMOS setup utility and disable the "FastBoot" option. The following note only applies to users with SCAM capable SCSI devices. Please ignore it if you do not have such a device. SCAM stands for "SCSI Configured AutoMagically." With SCAM Support, a host adapter can determine which SCSI IDs are not in use, and assign a free ID to a SCAM capable SCSI device. Normally SCAM is not enabled, and you need to set switches on the back of all of your SCSI peripherals to assign them unique SCSI IDs. You can enable SCAM support by adding /SCAM+ to your ASPI2DOS.SYS command line.

For example:

DEVICE = C:\SCSI\ASPI2DOS.SYS /D /SCAM+

This will work with any AIC-6260/6360/6370 based SCSI host adapter that does not have a BIOS enabled on the host adapter. If the host adapter has a BIOS, and it is enabled, the command line switch is ignored. If you have a SCAM capable BIOS (e.g. AHA-1530P), then you can enable or disable SCAM support by running SCSISelect.

ASPI8DOS.SYS

ASPI8DOS.SYS is Adaptec's ASPI manager for AIC-7850/7855/7870 based PCI SCSI host adapters. Running Adaptec EZ-SCSI will automatically detect which host adapter you have installed, which ASPI manager needs to be loaded, and what the correct command line switches are.

If you have an Adaptec PCI SCSI host adapter installed in your system, and you have EMM386.EXE loaded from MS-DOS versions up to 6.2, your system might hang if loading the ASPI manager after EMM386.EXE. This has been fixed in the EMM386.EXE that ships with MS-DOS 6.22 and later. If you experience this problem, you will either need to load ASPI8DOS.SYS before EMM386.EXE, or upgrade to MS-DOS 6.22 or later. If the ASPI manager detects a conflict, a message will be shown explaining how to work around the problem. Other ASPI modules (e.g. ASPICD.SYS) can continue to be loaded high.

There are several techniques for a driver to determine if its PCI SCSI host adapter is installed in your system. ASPI8DOS.SYS will determine which is the best method, and has been written to work around the EMM386.EXE problems discussed above. There are three command line switches you can use to force the ASPI manager to use a specific method. These are:

/MB - This command line switch will force the driver to use the PCI BIOS calls           (INT 1Ah) to scan for PCI SCSI host adapters.
/M1 - This command line switch will force the driver to use the "Mechanism 1"            method for scanning for PCI SCSI host adapters.
/M2 - This command line switch will force the driver to use the "Mechanism 2"            method for scanning for PCI SCSI host adapters.

For example, if you want to force the ASPI manager to find your PCI SCSI host adapter using PCI motherboard BIOS calls, your CONFIG.SYS would be:

DEVICE=C:\SCSI\ASPI8DOS.SYS /D /MB

NOTE: Most PCI systems do not support all three methods for scanning for PCI cards. It is recommended that you let the ASPI manager determine which method is suitable.

If you would like ASPI8DOS.SYS NOT to reset the SCSI bus, during driver initialization, you can use the /NORST command line switch. For example:

DEVICE=C:\SCSI\ASPI8DOS.SYS /D /NORST

If you would like ASPI8DOS.SYS to always reset the SCSI bus, during driver initialization, you can use the /RESET command line switch. For example:

If you would like ASPI8DOS.SYS to always reset the SCSI bus, during driver initialization, you can use the /RESET command line switch. For example:

DEVICE=C:\SCSI\ASPI8DOS.SYS /D /RESET

MCAM18XX.SYS

MCAM18XX.SYS is Adaptec's ASPI manager for its AHA-2920 PCI SCSI Host Adapters. Running Adaptec EZ-SCSI will automatically detect which host adapter you have installed, which ASPI manager needs to be loaded, and what the correct command line switches are.

The command line switches for MCAM18XX.SYS are currently not documented in our on-line "Device Driver Reference" Windows help file. The following command line switches are supported:

/u-     - Force Asynchronous Data Transfers on a Host Adapter.
/norst - Disables Hard Reset during initialization.
/y       - Disables parity checking.
/m1    - Force PCI bus scanning using the "Mechanism 1" method.
/m2    - Force PCI bus scanning using the "Mechanism 2" method.
/mb    - Force PCI bus scanning using INT 1A.
/l        - Enable multiple LUN support

If installing the AHA-2920 under Windows 3.1/3.11, Adaptec EZ-SCSI will automatically install the AHA2920.386 and AXPT.386 device drivers.

The following options are supported by AHA2920.386. To enable an option, add the following to the [386Enh] section of your SYSTEM.INI file:

AHA2920 = [/l-] [/u-] [/y]

/l-     - Disables multiple LUN support.
/u-    - Force Asynchronous Data Transfers on a Host Adapter.
/y      - Disables parity checking.

The following options are supported by AXPT.386. To enable an option, add the following to the [386Enh] section of your SYSTEM.INI file:

EZSCSI_OPTIONS = [/d]

/d - Displays version, adapter, and device information.

MA358.SYS

MA358.SYS is Adaptec's ASPI manager for its APA-358/358A parallel port SCSI host adapters. Running Adaptec EZ-SCSI will automatically detect which host adapter you have installed, which ASPI manager needs to be loaded, and what the correct command line switches are.

MA358.SYS, by default, will automatically detect the type of parallel port you are using. You can use the /Mnm switch to force a specific mode, and to set the amount of time that the MiniSCSI "Fast" read and write cycles are delayed (parallel ports on some computers require delays). You must specify values for both 'n' and 'm'.

The 'n' specifies the amount of delay. Allowable values for 'n' are 0 through 7, with each number representing a 125-nanosecond (ns) increment. A value of 7, for example, adds an 875 ns (7x125) delay to the cycles. The default of 0 specifies no delays.

The 'm' parameter determines the mode. The allowable values are shown in the following table:

Value of 'm'Meaning
0Auto-detect mode (the default). Automatically detects the type of port and configures the APA-358/358A for EPP if that port is detected to support EPP mode, otherwise the port is set up as a standard parallel port.
2Forces unidirectional mode.
4Forces bidirectional mode.
8Assumes EPP 8-bit bidirectional mode. For this to work, the parallel port must be set for EPP mode in the CMOS setup program or by configuring jumper settings on your EPP I/O card. For instructions on using the CMOS setup program, see your motherboard documentation. For instructions on configuring jumpers on your EPP I/O card, see your EPP I/O card documentation.

For example, if your parallel port is configured for EPP mode, and you would like the default read/write delay, your CONFIG.SYS would contain the following:

DEVICE=C:\SCSI\MA358.SYS /m08

If you change the MA358.SYS options in the config.sys file, turn the computer OFF and then ON again to have the changes take effect. (Do not simply reboot the computer using Ctrl-Alt-Del.)

If you have an original NEC Ultralite Versa laptop, and MA358.SYS is unable to detect the APA-358/358A SCSI host adapter, you should use the /m20 command line switch. For example:

DEVICE=C:\SCSI\MA358.SYS /m20

If you are using the APA-358 with an NEC Versa E or Versa V system, which uses the Western Digital Super I/O chip for FPP Parallel Ports (Chip #WD76C30), you should use the MA358NEC.SYS ASPI Manager in your CONFIG.SYS file instead of the standard MA358.SYS ASPI Manager.

If you are using an IBM ThinkPad 720 series computer, you should use the MA358IBM.SYS ASPI manager in your CONFIG.SYS file instead of the standard MA358.SYS ASPI manager.

When using the APA-358/358A, you should not configure your parallel port for ECP mode. Instead, you should configure the port for EPP mode.

MA358.SYS only supports one APA-358/358A in a system.

If you are using the APA-358/358A, and you are backing up from a SCSI disk drive to a SCSI tape drive, and you are using SMARTDRV, we recommend that you disable SMARTDRV write caching. Leaving write caching enabled can cause the backup to fail.

 
WINDOWS 3.1x/DOS GENERAL TROUBLESHOOTING

The ordering in which the Adaptec EZ-SCSI installer displays SCSI host adapters detected is dependent on a number of factors. If you have multiple SCSI host adapters, and the ordering displayed is not as you would expect, do not be alarmed. Adaptec EZ-SCSI will still properly edit your configuration files.

SMARTDRV 5.0 (in MS-DOS 6.2, Windows for Workgroups 3.11) now includes caching for CD-ROM drives. There is a problem with SMARTDRV in its support for XA formatted Compact Discs. If you experience "Not Ready" errors, using SMARTDRV 5.0, add /E:2048 to your SMARTDRV command line. For example:

C:\DOS\SMARTDRV /X /E:2048

You should install Adaptec EZ-SCSI to a drive letter that exists at boot time. This would NOT include RAM drives, network drives, removable drives, etc.

We have seen at least one case where an unstable video driver would cause EZ-SCSI for Windows to hang during installation. If you are experiencing similar problems, try using the standard VGA driver that comes with Windows. If EZ-SCSI for Windows then installs properly, you may want to contact your video card company for updated drivers.

In the unlikely event that you encounter a time-out failure when EZ-SCSI for Windows scans the SCSI bus, you should run EZ-SCSI for DOS first. Let it modify your CONFIG.SYS to load the appropriate ASPI managers; reboot your system. You should then be able to run EZ-SCSI for Windows.

If you have an AHA-2740W/2742W or AHA-2940W (Wide SCSI Host Adapter), the SCSI Interrogator for Windows (SHOWSCSI.EXE) will only show icons for SCSI IDs 0-7. You will not see IDs 8-15.

The SCSI Power Management Utility requires that the following line be present in your SYSTEM.INI file under the [386Enh] section:

device=VSCSIPWR.386

The first time you run SCSI Power Management you will be prompted to install the above driver. If you wish to disable the SCSI Power Management functions, you can remove this line from your SYSTEM.INI file in your WINDOWS subdirectory.

An issue with EMM386.EXE from DOS 6.2, and earlier, can cause problems with PCI systems. The HIGHSCAN option can overwrite the PCI BIOS area on some PCI systems, making the PCI BIOS detection useless. If your Adaptec PCI SCSI host adapter is not detected, be sure to remove the HIGHSCAN option from EMM386.EXE in your CONFIG.SYS file.

If you have a Trantor T160/T260 SCSI host adapter, EZ-SCSI will no longer scan for this adapter if you select the default installation option. In this case, you will need to select the custom installation option, and manually select the adapter, to properly install Adaptec EZ-SCSI.

The SCSI Power Management Utility is not compatible with the Trantor T160 and T260 SCSI Host Adapters.
