To remove the system board, follow these steps:
NOTE: If you are replacing the system board, remove all DIMMs, the video-
memory upgrade module (if present), the single-edge processor package
(SEPP) cartridge/heat sink assembly, and the guide bracket assembly from the
old system board and install them on the replacement board. Also, set the
jumpers on the new system board so that they are identical to those on the old
board, unless a microprocessor upgrade is being installed.
When you reinstall the system board (before you slide the system board back
to lock it in position), push down near each slot to engage the grounding clip
onto its corresponding tab. Push evenly on both sides of the system board as
you slide it into position (do not twist the system board).
