System Programs in Flash Memory:
System setup
programs and diagnostic tests are stored in flash memory.
Flash Memory Update:
A flash memory update is
required for the following conditions:
New versions of system programs.
New features or options are added.
To update the flash memory, do the following:
1. Get the appropriate diskette containing the update.
2. Insert the System Program Service Diskette into
drive A and power on the computer.
3. Select Update system programs from the menu.
System Board and CPU Card Checkout
The processing functions are performed by both the
system board and the CPU card. Processor problems can
be caused by either FRU. However, the CPU card
generally has a lower probability of failure. When a
numeric code calls the system board or the CPU card as a
FRU, or the CPU card is called by a diagnostic test by
showing FRU code 11, use the following procedure to
isolate the problem:
1. Run the system board test to verify the symptom.
This test verifies both the system board and the CPU
card. If no error is detected, return to “Checkout
Guide” on page 30.
2. If FRU code 10 appears, replace the system board
but do not replace the CPU card. Transfer the CPU
card from the old system board to the new system
board.
3. If FRU code 11 appears, reseat the CPU card.
4. Rerun the test to verify the fix.
5. If FRU code 11 remains, replace the CPU card.
If above procedure does not correct the problem, go to
“Undetermined Problems” on page 50.
Keyboard/Auxiliary Input Device
Checkout
Remove the external keyboard if the internal keyboard is to
be tested.
If the internal keyboard does not work or an unexpected
character appears, make sure that the three flexible cables
extending from the keyboard are correctly seated in the
connectors on the keyboard card.
If the keyboard cable connections are correct, check the
keyboard card.
