Beeps Description Troubleshooting steps
1 The memory refresh circuitry on the
system board is faulty.
Reseat the memory or replace with
modules you know are good.
2 Parity error in the first 64 KB of memory. Same as for 1 beep.
3 Memory failure in first 64 KB. Same as for 1 beep.
4 Memory failure in first 64 KB of
memory, or Timer 1 on the system
board is not functioning.
Remove all expansion cards.
■
If the beep code occurs even when all
expansion cards have been removed,
the system board is at fault.
■
If the beep code does not occur when
the expansion cards have been
removed, one of the cards is causing
the problem. Install the cards one at a
time until the problem happens again.
When the beep code returns, the most
recent card you installed is at fault.
