NOTES: If you are replacing the system board, remove all DIMMs, the
video-memory upgrade module (if present), the single-edge contact (SEC)
cartridge/heat sink assembly, and the guide bracket assembly from the old sys-
tem 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.
If the original system board has a NIC connector, ensure that the replacement
board has a NIC connector.
