CHAPTER 5: Driver Installation
5.8 Installing Drivers for SCO UNIX
The SCO UNIX device driver for your
Ultra2 LVD SCSI Host Adapter
will support
SCO UNIX System V/386 Release 3.2v4.0 or later; SCO Open Desktop v2.0, 3.0, or
later; and SCO Open Server Releases 3.0 and 5.0.x. The device drivers are
transferred from the floppy diskette to the hard drive, from which they are loaded
during system initialization. The two SCO UNIX device-driver files on Driver Disk 2
are the object file “driver.o” and the definition file “space.c”. Before proceeding,
you might want to have the following reference documentation handy in addition
to this manual:
• SCO UNIX documentation, installation and user’s guide
• The systems setup and installation guide
• The documentation for your system peripherals
• Any README.TXT file contained on Driver Disk 2. Such a file might contain
important updated information about driver-installation procedures.
The Adapter drivers developed for SCO UNIX will be installed on the disk drive
used for system initialization. The drivers are loaded during the system boot
routine and will remain resident on the drive. This is accomplished by following
one of the three installation procedures listed in this section: new SCO UNIX
installation, adding the device drivers to an existing SCO UNIX system (Adapter is
not bootable), or adding the drivers to an existing system and making the Adapter
bootable. These procedures differ significantly from one another. We strongly
suggest that you carefully read the instructions for the procedure you plan to use
and make sure you understand them before proceeding with the corresponding
system-configuration changes.
Another thing you need to check on before you go any further is the interrupt
and SCSI ID settings in your system:
• You can assign interrupt-request level (IRQ) 9, 11, or 15 to the Ultra2 LVD
SCSI Host Adapter; we recommend IRQ 11. Avoid using IRQ 10 as the
Adapter’s interrupt.
• Set the primary SCSI disk (the boot disk) to ID 0 (this is a first-time-installation
requirement)
• If you’ve attached a tape drive to the Adapter, set its target ID to 2. (Please be
aware that you will still need a third-party driver for any tape drive.)
•
If you’ve attached a CD-ROM drive to the Adapter, set its target ID to 5. (Please
be aware that you will still need a third-party driver for any CD-ROM drive.)
Please refer to your system’s documentation to set the interrupt levels and to your
peripherals’ documentation for help in setting SCSI IDs.
