11.0 Memory
Note: Power-off the system before removing or replacing parts.
00011000 indicates a system board parity check error.
Remove all memory module kits except the one in position 1. (The
system board memory positions for the reduced size system board, from
left to right, are 3, 2, 1. For all others, the system board memory
positions, from left to right, are 1, 2, 3, and, for the 80386 and
80486, 25-MHz systems, 4.) If the problem remains, replace the kit in
position 1. If the kit does not solve the problem, replace the system
board.
If the problem disappears after removing the memory module kits (you
should still have a kit in position 1), install the kits, one at a
time, until the problem returns. Replace the kit that caused the
problem to return. If the kit does not solve the problem, replace the
system board.
00011100 indicates a memory expansion adapter parity check error.
Remove the memory expansion adapters from the expansion slots one at a
time until you no longer get a 00011100 error. (If all of the
adapters have been removed and you still have a 00011100 error,
replace the system board.)
Remove the memory expansion kits from the adapter that was removed
last. Install the kits one at a time until the failure returns.
Replace the kit that caused the error to return; if that does not
solve the problem, replace the adapter.
00021500, 00021600 indicates a failing system board memory module kit.
If the error message does not indicate the location of the failing
kit, follow the procedure for a 00011000 error, described above.
