(first 64K RAM test failed)
1. Reseat the DIMM
2. Replace the lowest-numbered pair of DIMMs with an identical known good
pair of DIMMs; then, restart the server. If the beep code error remains, go
to 3. Return one DIMM at a time from the failed pair to its connector,
restarting the server after each DIMM, to identify the failed DIMM.
