Introduction
Important service information
Important
BIOS and device driver fixes are customer-installable.
The BIOS and device drivers are posted on the IBM
support site
http://www.ibm.com/pc/support/
Advise customers to contact the PC Company
HelpCenter at 800-772-2227 if they need assistance in
obtaining or installing any diskette fixes.
FRU replacement strategy
Before replacing parts
Ensure that all BIOS and device driver fixes are
installed before replacing any FRUs listed in this
manual.
Use the following strategy to prevent unnecessary FRU
replacement and service expense:
If you are instructed to replace a FRU, but the
replacement does not correct the problem,
reinstall the original FRU before you continue.
Some computers have both a processor board and a
system board. If you are instructed to replace either
the processor board or the system board, and the first
board that you replace does not correct the problem,
reinstall the original board, and then replace the other
(processor or system) board.
If an adapter or device consists of more than one
FRU, any of the FRUs may be the cause of the error.
Before replacing the adapter or device, remove the
FRUs, one by one, to see if the symptoms change.
Replace only the FRU that changed the symptoms.
Attention
A customized setup configuration (other than default
settings) may exist on the computer you are servicing.
Running Automatic Configuration may alter those set-
tings. Note the current configuration settings (using the
View Configuration option); then, when service has
been completed, verify that the settings are in place.
