Replacing a system board
Note:
1.
The BIOS and Vital Product Data (VPD) for the computer you are servicing must
be installed on the new system board (FRU) after it is installed in the computer.
To do this, you must run the Flash Update program using the Flash Update
diskette. See "BIOS levels" on page 93, "Vital product data" on page 92, and
"Flash (BIOS/VPD) update procedure" on page 93.
2.
Always ensure the latest level of BIOS is installed on the computer. A down
level BIOS may cause false errors and unnecessary replacement of the system
board.
3.
The processor is a separate FRU from the system board and is not included with
the system board FRU. If you are instructed to replace the system board, do the
following:
a.
Remove the processor from the old system board and install it on the new
system board.
b.
Refer to "System board layout" on page 17 to find the system board rocker
switch.
c.
Set switch 1 to the on position.
d.
Power-on the computer. The system senses the change in the switch setting
and resets to the default processor speed (266 MHz).
e.
Power-off the computer and set switch 1 back to the off position.
f.
Power-on the computer
1)
Select Advanced Setup from the Setup Utility Menu.
2)
Select Processor Speed Control from the Advanced Setup menu.
3)
Set the processor speed to match the speed of the installed processor.
4.
If the new system board does not correct the problem, reinstall the old system
board, then replace the processor.
