16 MB RAM, SIMM Set (0A,0B,0C,0D) present
Memory Set 0: 00000000 to 00FFFFFF, 16MB, 32768 good pages, 0 bad pages
Error: SIMM Set 1 (1E,1F,1G,1H), SSR = C94A
SIMM_1E = 16MB SIMM_1F = 16MB SIMM_1G = 16MB SIMM_1H = 00MB ??
Total of 16MB, 32768 good pages, 0 bad pages, 104 reserved pages
Normal operation not possible.
>>>
ACTION:
• If SIMM 1H is missing, install a SIMM.
• If SIMM 1H is present in socket, reseat the SIMM.
• If reseating SIMM 1H does not fix the problem then replace the SIMM
with a new SIMM.
• At this point the system board is probably bad.
Example 5–15 shows a memory failure due to a bad SIMM. In this case two
16-MB sets (4 SIMMs of 4 MB each) are present with one bad SIMM. SIMM
1H is marked as being bad.
