System Board and PC Card Slot

1.  The system unit serial number must be restored when the system board is replaced.
    To restore the system unit serial number, select the option 'Set system identification' on the  maintenance diskette. The flash ROM on the system board contains the vital product data (VPD) - that is,  the system unit serial number, system board serial number, and other computer-unique data.
2.  Do not turn off the computer while restoring the VPD.
    The system unit serial number is attached to the base cover.
3.  Before removing and replacing the system board assembly, make sure that the PC Cards are removed and the eject buttons  are not sticking out. If the PC Card eject buttons are sticking out, pull them further out slightly and fold them to the right, then  push up the system board assembly from the bottom.
