7800 UNIX Driver Instructions

The7800V211.DDZdriver supports the SCO UNIX 3.2v4.2, 3.2v5.x Open Desktop 3.0, Open Enterprise 5.x, and UNIXWare 2.x operating systems.

The 78UX_OLD.DDZ driver supports the SCO UNIX 3.2v4.0, SCO UNIX 3.2v4.2, and the UNIXWare 1.x operating systems.

  1. DOS BBS / UNIX Driver Disk Conversion instructions:

    THIS PROCEDURE ASSUMES THAT ANY CONFIGURATION OF ANY UNIX SYSTEM IS AVAILABLE TO PREPARE THE "Manager Set" FLOPPY DISK

  1. Copy the appropriate DDZ file to a DOS formatted floppy in the a: drive (3.5" DSHD 1.44 preferred). If you are able to download the file directly to a UNIX filesystem copy the file to a temporary directory /tmp and skip to step 4.
  2. Boot the UNIX computer and change to the /tmp directory (single-user maintenance mode is preferred, otherwise login as user root).
  3. Transfer the file to the UNIX hard disk. Use the appropriate UNIX copy command.
    In SCO XENIX or SCO UNIX the command is:
    doscp a:7800V211.DDZ /tmp/7800V211.DDZ

    In UnixWare use the Disks-etc window and click on the floppy diskette icon. Move the 7800V211.ddz file to a temporary folder and rename the file using the mv command to: 7800V211.dd.Z.

    If you have a version of SCO UNIX based on release 3.2v4.0 or 3.2v4.1 or UNIXWare 1.x substitute UNIX_OLD for 7800V211. This adapter has no driver support for SCO UNIX release 3.2v2.0 or earlier.

  4. Rename the file 7800V211.DDZ to 7800v211.dd.Z.
    cd /tmp
    mv 7800v211.DDZ 7800v211.dd.Z
  5. Format a fresh UNIX floppy (size: 3.5" DSHD 1.44).

    In SCO XENIX or SCO UNIX the command is:

    format /dev/rfd0135ds18M

    In UnixWare the command is:

    format /dev/rdsk/f0q18dt
  6. Uncompress the file.

    Use the UNIX command:

    uncompress 7800V211.dd.Z

    This will convert the file to 7800V211.dd

  7. Copy the image file to the floppy disk:

    In SCO XENIX, UNIX or Open DeskTop (ODT), the command is:

    dd if=7800V211.dd of=/dev/rfd0135ds18

    In UnixWare the command is:

    dd if=7800V211.dd of=/dev/rdsk/f0q18dt
  8. If you have a version of SCO UNIX that was originally installed from 5.25" floppies, then you need to follow the instructions in the text file UNIX3TO5.TXT to be able to convert the 3.5" driver diskette to a 5.25" driver diskette.

  1. Installation instructions:

    Use this disk for "normal" installation/upgrade purposes per standard documentation.

  1. SCO UNIX fresh installation:

  1. If you are using SCO UNIX 3.2v4.x or ODT 2.x or 3.x then during a fresh install type:
    link
    at the Boot: prompt and press (ENTER). Use the driver name of
    alad when prompted for the driver package name.
  2. If you are using SCO Open Enterprise 5.0 or 5.02 during a fresh
    install type: ahslink
    at the Boot: prompt and press (ENTER), use the driver name of: alad325 when prompted for the driver package name. You will be notified that an existing "aladinit" driver already exists and asked which routine you wish to replace. Choose routine 211 to replace and continue with the installation.
  3. If you are using SCO Open Enterprise 5.04 during a fresh install type:ahslink at the Boot: prompt and press (ENTER), use the driver name of alad325 when prompted for the driver package name. You will be notified that an existing "aladinit" driver already exists and asked which routine you wish to replace. Choose routine 25 to replace and continue with the installation.
  1. If SCO UNIX is already up and running use the installpkg command to install the driver.
  2. If you are doing a fresh install of UnixWare then insert the driver disk when you are prompted for the Host Bus Adapters Drivers Diskette. The PCI host adapter must be assigned IRQ 10 on the PCI bus for UnixWare 1.x and will not install if using another IRQ. Extended BIOS translation should be disabled on our adapter before starting the installation. Use the driver package adsl from the disk created from UNIX_OLD for UnixWare 1.x. Use the driver package adsl20 from the disk created from 7800v211 for UnixWare 2.0x. Use the driver package adsl from the disk created from 7800v211 for UnixWare 2.1x.
  3. If you have UnixWare 1.x in an up and running system use the pkgadd command to install the driver. IE. pkgadd -d diskette1. Use the driver package adsl from the disk created from UNIX_OLD. Make a backup copy of the unix kernel in the stand directory by copying unix to unix.work. If the hard drive is to boot from our driver then edit the file /etc/conf/sdevice.d and delete the line $loadable adsl. Rebuild the kernel by typing in the command "/etc/conf/bin/idbuild -M adsl" and pressing (ENTER). If the kernel will not boot after a shutdown you will be prompted for which kernel you wish to boot from. To recover type unix.work and press (ENTER).
  4. If you have UnixWare 2.0x in an up and running system use the pkgadd command to install the driver. IE. pkgadd -d diskette1. Use the driver package adsl20. Make a backup copy of the unix kernel in the stand directory by copying unix to unix.work. If the hard drive is to boot from our driver then edit the file /etc/conf/sdevice.d and add the line $static below the line $version 2. Rebuild the kernel by typing in the command "/etc/conf/bin/idbuild -B" and pressing (ENTER). If the kernel does not reboot after a shutdown you can recover by booting off of the old kernel by typing KERNEL=unix.work at the [boot]# prompt and pressing (ENTER).
  5. If you have UnixWare 2.1x in an up and running system use the pkgadd command to install the driver. IE. pkgadd -d diskette1. Use the driver package adsl. Make a backup copy of the unix kernel in the stand directory by copying unix to unix.work. If the hard drive is to boot from our driver then edit the file /etc/conf/sdevice.d and add the line $static below the line $version 2. Rebuild the kernel by typing in the command "/etc/conf/bin/idbuild -B" and pressing (ENTER). If the kernel does not reboot after a shutdown you can recover by booting off of the old kernel by typing KERNEL=unix.work at the [boot]# prompt and pressing (ENTER).
  1. Modifiable parameters in SCO UNIX:
  1. Tag command queuing can be disabled in SCO UNIX by editing the file space.c in the directory /etc/conf/pack.d/alad
    change the line: int alad_do_tagged=1;
    to: int alad_do_tagged=0;
  2. Scatter gathering can be disabled by editing the file space.c in the directory /etc/conf/pack.d/alad
    change the line: int alad_do_sgatter=1;
    to: int alad_do_sgatter=0;
  3. Selection timeout can be changed for the first adapter by editing the file /etc/conf/pack.d/alad/space.c

    The original line is: aha_change alad_sel_timeout[SCSI_NALAD]; To force the host adapter to wait 256 ms before reporting a SCSI selection timeout error change this line to:

    aha_change alad_sel_timeout[SCSI_NALAD]={1,SEL_256};

    To force the host adapter to wait 32 ms before reporting a SCSI selection timeout error change this line to:

    aha_change alad_sel_timeout[SCSI_NALAD]={1,SEL_32};

    To force the second host adapter to wait 256 ms before reporting a SCSI selection timeout error change this line to:

    aha_change alad_sel_timeout[SCSI_NALAD]={0,0,1,SEL_256};

    The kernel must be rebuilt for these changes to take effect. Other changeable parameters are documented in the space.c file.
