BIOS errors and warnings
The BIOS generates warnings/errors on invalid memory configurations:
If the BIOS can find a valid memory configuration by disabling plugged-in memory, it does so and
reports a warning during POST. the workstation can still be started. The warning will indicate the
location of the failed DIMM on the system board.
If there is no way for the BIOS to obtain a valid memory configuration by disabling plugged-in
memory, the BIOS halts with a diagnostics 2006 code for memory error (five beeps and blinks).
