Note
The value listed by each SIMM is either 16 MB or 64 MB which
indicates the full size of the set of SIMMs if all are present.
ACTION:
• If SIMM 1F is missing, install a SIMM.
• If SIMM 1F is present in socket, reseat the SIMM.
• If reseating SIMM 1F does not fix the problem, replace the SIMM with a
new SIMM.
• At this point the system board is probably bad. If no new system board is
available, try moving the SIMMs to the other set of sockets.
Example 5–14 shows a memory failure due to a missing SIMM. In this case
two 16-MB sets (4 SIMMs of 4 MB each) are present with one SIMM missing
in Set 1. Since one set of memory is fully usable, all testing is completed. At
the end SHOW MEMORY is automatically executed as before. SIMM 1H is
missing or not installed correctly. The system is usable but with only 16 MB of
memory instead of 32 MB.
