Using Specified Cfg File - Intel AC450NX Product Manual

Using Specified CFG File

The utility can be run with the command line parameter of -cfg filename.cfg. The filename can be
any DOS accepted, eight-character filename string. The utility loads the specified CFG file and
uses the entries in the configuration file to probe the hardware and to select the proper SDRs to
load into nonvolatile storage.
Displaying Utility Title and Version
The utility displays its title
FRU & SDR Load Utility, Version xx.xx
Configuration File
The configuration file is in ASCII text. The utility executes commands formed by the strings
present in the configuration file. These commands cause the utility to perform various tasks
needed to ultimately load the proper SDRs into the nonvolatile storage of the BMC and possibly
generic FRU devices. Because some of the commands are interactive, you are required to make a
choice.
Prompting for Product Level FRU Information
Through the use of a configuration file, the utility may prompt the user for FRU information.
Filtering Sensor Data Record From the SDR File
The MASTER.SDR file has all the possible SDRs for the system. These records may need to be
filtered based on the current product configuration. The configuration file directs the filtering of
the SDRs.
Updating FRU Nonvolatile Storage Area
After the configuration is determined, the utility updates the FRU nonvolatile storage area. First it
verifies the Common Header area and checksum from the specified FRU file. The Internal Use
Area is read out of the specified .FRU file and is programmed into the nonvolatile storage. The
Chassis Area is read out of the specified .FRU file. Last it reads the Product Area out of the
specified FRU file, then the area is programmed into the FRU nonvolatile storage. All areas are
also written to the FRU.TMP file.
