3.2.3.9.5.1 BIOS Policies on Uncorrectable Errors
For uncorrectable errors, the BIOS logs a single “Uncorrectable Error” SEL entry. The BIOS
then generates an NMI.
3.2.3.10 Memory Error Reporting
Memory errors are reported through a variety of platform-specific elements, as described in the
following table.
Table 9. Memory Error Reporting Agent Summary
Platform Element Description
Event Logging When a memory error occurs at runtime, the BIOS logs the error into the system
event log in the Integrated Baseboard Management Controller’s (Integrated BMC)
repository.
BIOS Diagnostic/Error Screen At the end of POST, memory errors found during MemBIST are reported in the
BIOS Error Manager.
Beep Codes The BIOS emits a beep code when the system has no memory or when a link
failure is detected during memory discovery, causing all memory to be mapped out.
BIOS Setup Screen When FBDIMMs fail Memory BIST or RAS configuration errors occur, the FBDIMM
status is captured in the Advanced > Memory screen in the BIOS setup.
DIMM Fault Indicator LEDs Intel
®
server boards and systems that use the Intel
®
5400 Chipset have a set of
Fault Indicator LEDs on the board, one LED per DIMM socket. These LEDs are
used for indicating failed/faulty FBDIMMs.
System Fault/Status LEDs Intel
®
server boards and systems that use the Intel
®
5400 Chipset provide a
specific LED on the front panel and rear I/O Panel that indicates the state of the
system. When a memory error occurs such that the performance of the memory
subsystem is affected, the BIOS sends a request to the Integrated BMC to initiate a
Status LED state change.
NMI Generation The BIOS triggers/initiates an NMI to halt the system when a critical error occurs.
3.2.3.10.1 Memory BIST Error Reporting
The Error Manager screen in the BIOS captures Memory BIST failures that occurred during the
current POST.
Table 10. Memory Errors Captured by Error Manager
Specific Error Error Class Error Code Error Text Description
Configuration Error Pause 0x85F0 Memory was not
configured for the
selected memory RAS
mode.
Failure of BIOS to configure
the memory system in the
selected RAS mode.
Memory BIST Failure Pause 0x852x DIMM_xx failed self test
(BIST).
During normal Memory BIST
operation in POST, the BIOS
detected that DIMM_xx failed
to pass Memory BIST.
Note: x = the instance number of the DIMM that failed.
