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.
