Notes:
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 87, "Vital product data" on page 86, and "Flash (BIOS/VPD)
update procedure" on page 88.
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.
4. If the new system board does not correct the problem, reinstall the options on the old
system board, reinstall the old system board, then replace the processor.
