4. It is possible that another installed adapter is causing the problem.
Remove all installed adapters except the one the CD-ROM drive is attached
to and the one used for the console.
Try to boot the standalone diagnostics again.
If unable to load standalone diagnostics, go to step 5
If standalone diagnostics load, re-install adapters (and attached devices as
applicable) one at a time and retry the boot operation until the problem
recurs. Then replace the adapter or device that caused the problem (I/O
board can also cause the device or adapter to fail). Go to "MAP 0410: Repair
Checkout" in the Diagnostic Information for Multiple Bus Systems.
5. Either the CD-ROM drive, SCSI adapter, the graphics adapter, or the I/O board
is most likely defective. A TTY terminal attached to the serial port also can be
used to determine if the graphics adapter is causing the problem. This is done by
removing the graphics adapter, attaching a TTY to the serial, and retrying stand-
alone diagnostics. If the standalone diagnostics load, the graphic adapter should
be replaced.
Replace CD-ROM drive.
If the CD-ROM drive is attached to a SCSI adapter card rather than the inte-
grated SCSI adapter on the I/O board, replace SCSI adapter.
Replace I/O Board.(See notes on 3-1.)
If you replaced the indicated FRUs and the problem is still not corrected, or
the above descriptions did not address your particular situation, go to "MAP
1540: Minimum Configuration" on page 2-37.
Go to "MAP 0410: Repair Checkout" in the Diagnostic Information for Mul-
tiple Bus Systems.
