Troubleshooting
2–9
When several bursts of beeps are generated, listen carefully and
remember the numeric beep code pattern. This pattern establishes
the secondary level of beep codes. Table 2–3 lists the secondary
beep codes and the test in-progress or test failure that corresponds
to the numeric beep code pattern. For example, "2-1-4" (a burst of
two beeps, a single beep, and a burst of four beeps) indicates that
a failure of bit 3 in the first 64K of RAM has been detected.

Any of the RAM failures can be caused by a SIMM not being properly seated in
its socket.
