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).
