SCO Unix Driver Installation

10Overview

The I/OHIGHWAY SCO UNIX device driver will support SCO UNIX System V/386 Release 3.2v4.0 or later, SCO Open Desktop v2.0, v3.0 or later, and SCO Open Server Release 3.0 & 5.0.x. The device driver is transferred from the floppy diskette to the hard drive where it’s loaded during system initialization.

The installation of Initio device drivers to support SCO UNIX include the following software files and may be found on the INI-9XXXU/9XXXUW DRIVER DISK 2.

Driver.o	Device driver object file
Space.c	Device driver definition file

Reference Documentation:

•SCO UNIX documentation, installation and user’s guide

•The systems setup and installation guide

•The documentation for system peripherals

•Initio documentation for the SCSI host adapter

Installation

The SCO UNIX drivers developed by Initio will be installed on the disk drive used for sys- tem initialization. It is strongly suggested that the selected procedure be read and under- stood before continuing with the system configuration or change. Please read the instruc- tions carefully.

Updating interrupts and hardware settings

The following interrupt configuration settings are suggested as the most effective means of providing a controller interrupt to the host adapter:

•Host Adapter interrupt levels available are 9,11, 15, (IRQ 11 is recommended)

•Avoid using interrupt 10 as the controller interrupt.

•Set first SCSI disk ID to 0 (first time install requirement)

•Set tape target ID to 2. (If tape is in use)

•Set CD-ROM target ID to 5. (If CD-ROM is in use)

Please Refer to your system documentation to set the interrupt levels and your peripheral documentation for help in setting SCSI IDs.
