Installation of Non-PnP host adapters
|
|
- Before installing the host adapter in your system, check for available resources. Look in Device Manager under Computer Properties. Here you can obtain a list of resources (IRQ, DMA, I/O Port & Memory) that are currently in use by system. Determine which resources are available to set your host adapter to. The steps in getting to this location are: Open Control Panel, double click on System Icon, select the Device Manager tab, and double click the computer icon at the top of the list. This will open the Computer Properties. All currently used resources will be listed. If there are no available Interrupt Requests (IRQ) contact your system manufacturer to assist in freeing up an interrupt request (IRQ) before proceeding with the installation.
- Once you have determined what resources are available in your system, set the host adapter to the available resources using the adapter jumper(s), BIOS utility or configuration utility and install it in your system.
- If your system supports PCI, access the system setup (CMOS, BIOS) during post to make sure that the resources being used for the host adapter are not being reserved for PCI. Some systems will have a listing or IRQ (Interrupt request) setting that can be set to either PCI/PNP or Legacy ISA. Set the IRQ the host adapter is using to "Legacy ISA".
- To install the host adapter open the Control Panel and select "Add New Hardware" icon. This will bring up the "Add New Hardware Wizard". Select "No" when you are prompted to automatically search for new hardware (NOTE: Windows 98 will always search for PnP Hardware. However, when it asks to scan for NoN-PnP Hardware, select NO). Select "SCSI Controllers" and select the Adaptec Host adapter you want to install. The install program will ask for the driver source if it is not already on your PC system. You must have access to the distribution disks or Windows 95/98 CD-ROM in order for the installation to proceed.
- Verify that the resources Windows 95/98 selected are the same as the card resource settings.
- If the resources that Windows 95/98 has chosen for the adapter driver differ from the resources the host adapter is set to, change the resources on the adapter to the Windows 95 settings.
- Restart your system. To verify that the Adaptec driver is loading properly, look in Device Manager under "SCSI Controllers". The driver, if properly loaded, will be listed with no Yellow exclamation mark or red X present over the adapter icon.
- To verify that all of the devices you have connected to the adapter are being detected by Windows 95/98, check in Device Manager. Do this by selecting "View Devices by Connection", then look on the list for the SCSI card driver (on some systems it may be listed under "Plug and Play BIOS".) Double click (or click on the plus to the left) on the driver for the adapter you have installed and all connected devices should be listed.
- You can obtain information on device settings in Device Manager by looking under the appropriate category listing. CD-ROMs will appears under the CD-ROM listing. Hard drives and removable media will be listed under Disk Drives. Since scanners do not have embedded driver support, you will be required to install a scanner driver. Once this is installed, it will be listed in Device Manager under Scanner.
If the host adapter driver is listed in Device Manager with a yellow exclamation or Red X, or if a device fails to be detected, refer to the Windows 95/98 Frequently Asked Questions.

Installation of PNP/PCI host adapters
|
|
- Before installing the host adapter in your system, check for available resources. Look in Device Manager under Computer Properties. Here you can obtain a list of resources (IRQ, DMA, I/O Port & Memory) that are currently in use by system. Determine which resources are available to set your host adapter to. The steps in getting to this location are: Open Control Panel, double click on System Icon, select the Device Manager tab, and double click the computer icon at the top of the list. This will open the Computer Properties. All currently used resources will be listed. If there are no available Interrupt Requests (IRQ) contact your system manufacturer to assist in freeing up an interrupt request (IRQ) before proceeding with the installation. Some systems may allow PCI host adapters to share resources. Either try inserting the card and proceed, or contact the system manufacturer to verify.
- There is no way on a PCI adapter to assign specific resources to the card, either physically or through SCSI Select settings. The motherboard BIOS does all of the resource allocation for PCI adapters. On some motherboards you may have options in the system CMOS, under the PCI/PNP configuration section, to allow some resource allocation. You may also be able to affect resource allocation by changing PCI slots. Check with your system or motherboard manufacturer for further information.
- Before installing a driver in Windows 95/98 make sure that you see a BIOS banner for the adapter during post. This BIOS information will show you what adapter you have installed, the BIOS version and what devices are connected to the adapter. If the host adapter has a BIOS, then this information must appear for the adapter to install properly in Windows 95/98. If the host adapter does not have a BIOS chip you will not see this information during post. You must install the driver in Windows 95/98 before you can see the adapter and device.
- If you do not get a BIOS Banner during post for a Host adapter that has a BIOS chip, or if you get a BIOS banner but get an error "Host Adapter Configuration Error", do not proceed with installing the adapter in Windows 95/98 until this has been resolved. This error at system boot indicates the PCI interrupt has not been configured correctly. Check the system CMOS/BIOS setup for PCI slot enable, bus mastering enable, IRQ triggering set to Level, enough available IRQs reserved for PCI/PNP. These settings can usually be found in the system CMOS under PCI or PNP configuration. Also try installing the adapter in another PCI slot.
- Windows 95/98 will automatically detect the adapter during boot. You will be prompted that Windows 95/98 has detected new hardware. If the driver source is already on the PC, Windows 95/98 will inform you that it is installing the driver and prompt you to restart the system once the driver is installed. If the driver source is not already on the PC Windows 95/98 will prompt you for a drivers disk from the manufacturer or the Windows 95/98 CD-ROM.
- Once the system is rebooted, verify that the driver is loaded successfully in Windows 95/98 Device Manager. In Control Panel, double click on the System icon, then open Device Manager. There should be a listing for "SCSI controllers". The driver should be listed with no yellow exclamation or red X. You can review the resources the driver is using by double clicking on the driver and selecting the Resource tab. This will also give you conflicting device list information.
- Once the driver is installed and the system has been rebooted, if the system fails to boot to Windows 95/98, this is an indication of a resource conflict. If the system locks up with memory errors or with no video, this could be a BIOS address conflict. Update the system BIOS to the most recent version. If the system locks up or freezes on the driver load, check for IRQ conflict. Put the adapter in another PCI slot (primary or 1st slot preferred). Check the system CMOS setup for any PCI slot or IRQ options that will allow you to reserve an IRQ for PCI/PNP.
- Once the system boots to Windows 95/98, if the driver still has a yellow exclamation or red X, then update the driver with the latest version from the Adaptec web site. You can update the driver by going to Device Manager. Under SCSI Controllers double click on the driver and select Driver tab. Select the button "Update Driver". This will allow you to update the driver. You can also just copy the updated driver to the Windows/system/iosubsys directory in Windows explorer. This will overwrite the current driver with the latest.
- If installing a PNP but non-PCI adapter in Win95, and the driver is not loading, then disable PNP on the adapter. Check your adapter documentation for instructions on how to disable PNP. Then use the instructions above for "Installation of Non-PNP host adapters".
