Description
Injects errors to verify various RAS
features.
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.
