software files and may be found on the INI-9XXXU/9XXXUW DRIVER DISK 2.

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.
