DIGITAL Personal Workstation a/au-Series systems that include a SCSI bus currently use the Qlogic 1040UW Ultra Wide SCSI PCI host adapter. At this time, DIGITAL supports up to four drives attached to the adapter's wide internal bus. Narrow devices can be attached to that bus when a 68- to 50-pin adapter is used. No external devices are supported on the same adapter used for internal devices. Add another SCSI adapter if you need to attach external SCSI devices.

Configuring the SCSI Host Adapter

The SCSI adapter is configured using the eeromcfg.exe utility.

Configuring SCSI IDs

The DIGITAL Personal Workstation a Series currently supports up to four internal SCSI devices. The adapter can support SCSI IDs ranging from 0 to 15. Each SCSI device must have a unique SCSI ID. Typically, the host adapter is ID 7.

Note: The CD-ROM drive is an ATAPI device attached to the IDE port.
