Fwupdate provides the following functions.
•
SAL/BMC update
This function updates the SAL (FHW/SAL Spool) and the BMC (external flash) to
SAL/BMC in the integrated ROM file specified by file name.
When the "target machine type" and "model" existing in the integrated ROM file is
unmatched to the system, the update is not performed.
SAL Spool is used as a back up of SAL. When SAL in FWH is damaged, the SAL is
recovered from SAL Spool by using the SAL firmware recovery function.
•
Takeover of NVM area
NVM area in FWH stores the EFI parameters such as EFI boot option. By copying
the contents of NVM area to take over, resetting of EFI parameters can be omitted.
When version of NVM area managed by SAL is unmatched between FWH SAL and
integrated ROM SAL, the takeover is not performed.
•
SDR write function
Writes SDR data in the integrated ROM file.
A manual system reset is required as part of the FWUPDATE process.
