ACTION

• Reseat the SIMM 1H.

• 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 5–16 indicates that a large SIMM is mixed in with a set of small

SIMMs. If a full set of SIMMs is present and one or more is the incorrect

size then the diagnostic code will conﬁgure the set as a small set and run the

tests. In this example, SIMM 1G is the wrong size SIMM. Because the set is

conﬁgured as a small set, it is usable as a 16-MB set.
