Comparing the FRU File

The configuration "COMPARE" command allows the validation of information to what exists in
the non-volatile storage device without programming that information. The "COMPARE"
command is used in a configuration file, and placed on the same line after the FRU name to be
compared.
The compare functionality does a byte-by-byte comparison of the non-volatile storage device and
what was to be programmed. The internal use area is never compared; this utility considers all
bytes of the internal use area to be dynamic and subject to change at will by the firmware. In the
board area, the manufacturing date and time, and the board area checksum are also not compared,
although the rest of the board area bytes are compared.

Loads Specified SDR File

The normal method of loading an SDR file is through the use of a configuration file. Typically all
possible Sensor Data Records exist in one master SDR file. Each SDR file name is specified after
the SDRNAME configuration command. Through the configuration file, tags may be use to
selectively chose which records are to be programmed using tags. The maximum allowable length
of any Sensor Data Record is 64 bytes. Any larger records are flagged as an error.
Example:
Writing SDR Record #36
Reading SDR Repository
SDR file was successfully written!
Programming complete, reboot server for normal operation
Comparing the SDR File
The configuration "COMPARE" allows the comparing of SDR information to what is in the SDR
Repository without programming that information. The "COMPARE" command is used in a
configuration file and placed on the same line after the SDR name to be compared. The compare
feature does a byte-by-byte comparison of the non-volatile storage device and what was to be
programmed. No checksum is used. During a comparison, the first two bytes of each Sensor Data
Record are ignored, because when the repository was programmed, the first two SDR bytes were
modified by the BMC and a pointer inserted.

Functional Operation

Display Utility Title and Version

The utility displays as its title during development:
FRUSDR Load Utility, Version 2.0 Build X where 'X' is the build number for the
particular version of the utility.
Upon final release, the banner is modified and the build status removed, therefore:
FRU & SDR Load Utility, EFI Version 2.0, Build 4
Will become the production release:
FRU & SDR Load Utility, EFI Version 2.0
