User Notification
The BIOS will try to map out defective rows found during base memory test but
will end up in an infinite reset loop.
“First row test”
- displayed on the upper LCD line
“0064 MB”
- displayed on the lower LCD line
“BASE MEMORY TEST”
- displayed on the upper LCD line
“ERRORS IN MEMORY”

“RESETTING SYSTEM”

Upon reset, the above messages will display again on the LCD and will keep

User Action
1. Use the out-of-band mechanism of reading System Event Log (Intel’s
Server Management software, specifically DPC, can be used for this) to
determine the location of the row of defective DIMMs from the
SELViewer Utility or by running either the Intel Server Control (ISC) or
Direct Platform Control (DPC) to read the System Event Log (SEL).
Replace the defective DIMMs (in the example it is 5-8). On replacing the
DIMMs, make sure the size and HP part number match.
2. Clear CMOS via the front panel or via clear CMOS jumper in order to
clear previous defective DIMM history.
3. Power on the system to continue.
Error Logging
The defective row/DIMM(s) found during this test case will be logged to the SEL
and reported on screen.
Extended Memory Test
The extended memory test takes effect after both the first row test and the base
memory test have passed. The Extended Memory Test will test the physical
memory above 2 GB to a maximum of the total installed memory. Any errors
found will be detected to the failing memory row and recorded into the CMOS
history bits for processing during the next reset. Since this occurs after system
POST, the BIOS will not reset the system. Instead, error messages will be
displayed on the video screen.
