Error code 110 indicates that a parity check error on the
system board was detected. The error is caused by the
SIMM card or the system board.
To isolate the FRUs, remove the SIMM card and run the
memory test again.
If an error occurs without the SIMM card, replace the
system board.
Otherwise, replace the SIMM card.
Note: The system board contains the first 4MB of the
memory.
