Table 9-47: Firmware Upgrade Write Command
Firmware Upgrade Complete Command
The Firmware Upgrade Complete command completes the programming of the IPMC.
When the Boot Loader receives this request, it writes any remaining cached data to flash,
sends a success reply, exits the upgrade mode, and reboots. After reboot, the Boot Loader
performs the standard firmware integrity checks and if they are a success, boots the IPMC
firmware. This command is supported only by the Boot Loader. If the IPMC firmware
receives this command, it sends a reply with the 0xC1 (Invalid Command) completion code.

Firmware Upgrade Restore Backup Command
The Firmware Upgrade Restore Backup command makes the Boot Loader restore the firm-
ware from the backup image. If the Boot Loader receives this command, it does the follow-
ing:
• Erases the slave H8S flash memory
• Erases the master H8S firmware area
• Programs the slave H8S firmware with the backup image stored in the master H8S flash
memory
• Programs the master H8S firmware area with the backup image stored in the master
H8S flash memory
