System Board Replacement (Type 8639)

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 shipped with the  new system board FRU. See 'BIOS Levels' 'Vital Product Data', and 'Flash (BIOS/VPD) Update Procedure'
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.
4.  Install the processor from the old system board on the new system board.
5.  If any of the following options are on the old system board,  install them on the new system board.
   •  External cache memory and cache tag RAM
   •  Memory modules
   •  Extended video memory

6.  Ensure that the new system board jumper settings  match the old system board jumper settings.
7.  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.
