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 or memory riser.

●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).
