Step 4
It is possible that another installed adapter is causing the problem. Do the following:
1. Remove all installed adapters except the one the CD-ROM drive is attached to and
the one used for the console.
2. Try to boot the standalone diagnostics again.
3. If unable to load standalone diagnostics, go to “Step 5”.
4. If standalone diagnostics load, reinstall 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. (The primary I/O drawer
backplane can also cause the device or adapter to fail.) Go to

Step 5
The CD-ROM drive, IDE cable, graphics adapter (if installed), or the system 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 port, and retrying standalone
diagnostics. If the standalone diagnostics load, replace the graphics adapter.
1. Replace the CD-ROM drive.
2. Replace the IDE cable.
3. Replace the system board.
4. 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 59.
