Description
Provides software recovery for
uncorrectable errors to improve system
availability.
Improves system availability.
The OBB system accesses MCA registers
by using the Platform Environment Control
Interface (PECI). If a fatal error occurs in
the system, the out-of-band system collects
onsite data to facilitate fault analysis and
locating and improve system serviceability.
The BIOS processes errors and reports the
error information to the OS and the server in
compliance with specifications to improve
system serviceability.
The BIOS provides physical unit
information for DIMM errors, and the OS
traces and predicts errors, and isolates error
memory pages.
