The BIOS setup utility executes a memory test prior to configuring 
the memory in POST and when a memory board is inserted into 
the system during a memory hot-removal or hot-add operation. 
If a DIMM fails the memory test, an LED will light on the memory 
board to identify the location of the bad DIMM and the DIMM 
bank will be disabled. The failed DIMM is logged onto the System 
Event Log (SEL). BIOS setup utility will disable the DIMM and/or the 
memory board. Upon subsequent reboots, this memory is not 
initialized unless the BIOS setup option “Reset all system memory” 
or “Retest board memory” is selected. Refer to “4 BIOS setup” on 
page 87 for more information.
