Troubleshooting 11
Example 2–1 shows the second 8-digit number of the MEM display in
the configuration table. Each digit represents a SIMM memory module.
A code other than 0 in any of the digits indicates an error on a memory
SIMM.
Each digit contains the status of four banks of memory (1 bank = 1 Mbyte
of memory).
