Chapter 11
Case 3
The system is populated with more than one row of memory, the first row
memory test encounters a SBE (Single Bit Error), and the base row test encounters
memory errors but not on all the rows. In this case, the BIOS will write the failing
row from first row test into CMOS history, map out the first row of DIMMs, and
continues with base memory testing. The base memory testing will write the
failing rows into CMOS and map out the defective rows upon reset. Since not all
the memory in base memory test (< 2 GB) gets mapped out, then the system will
continue to boot with the remaining good memory found during the base memory
test.
User Notification
The defective rows found during first row test and base memory test will be
mapped out and the system will continue to boot with the remaining base memory.
An error message will be displayed to video for the mapped out defect DIMM.
Example: Consider a system that is populated with three rows of 256 MB
DIMMS in the upper board rows 1-4, row 5-8, and row 9-12. If a memory error
was detected in DIMM 5 during the first row memory test and a memory error
was encountered in DIMM 1 during base test, the following messages will appear
on the LCD:
"First row test"
"0064 MB"
"BASE MEMORY TEST"
"ERRORS IN MEMORY"
"RESETTING SYSTEM"
Upon reset, you will see the following messages on the LCD:
"First row test"
"0064 MB"
"BASE MEMORY TEST" - displayed on the upper LCD line
The system will continue to boot and the following messages will appear on the
screen during POST:
3072 MB Total Memory Installed
1024 MB Configured
1024 MB Tested
