Intel-based Computers
Run the Compaq System Configuration Utility from
the hard drive or from diskette, record the option
board settings (use worksheet in Table 5-1), and
restart the computer. Configure all the boards in the
system, then check the following:
• Verify that all installed boards appear in the slot
diagram. Add any missing boards.
• Verify that the switch settings shown by the
Compaq System Configuration Utility match the
physical settings used on the boards (see
worksheet). Ensure that the actual board
settings match the settings shown by the utility.
AlphaServers
Use the SRM console command line system to
verify and/or correct the adapter configuration.
Use AlphaBios to verify and/or correct the adapter
configuration.

SRM console or AlphaBios
does not recognize the
tape drive.
• Check the connections of the signal cable.
• Check the seating of the controller/adapter.
• Ensure tape drive power cable is oriented
correctly and inserted completely.
• If multiple SCSI devices are used, make sure
that on each SCSI bus, each device has a
unique SCSI ID.
• Your drive should be shipped from the factory
with all terminators removed. Verify that all
terminators have been removed.
• If none of these steps solve the problem, then
remove, replace, and test each of the following
components separately: cables, tape drive, and
the controller.
• Contact a Compaq authorized service provider.
