10.9 IPMI Firmware Code
10.9.1 Firmware Upgrade
The IPMI's operational code can be upgraded via the open-source tool “ipmitool” or via uEFI BIOS com-
mands. The upgrade tool/commands allow download and activation of new operational code and also
rollback to the “last known good” operational code. For further information on the IPMI firmware up-
grade, refer to the Chapter 9, uEFI BIOS, and the IPMI Firmware User Guide.
10.9.2 IPMI Firmware and FRU Data Write Protection
Write protection of the AM4024(E) is enabled if the DIP Switch SW2, switch 3, is set to ON . If the board
is write-protected, neither the IPMI firmware or the FRU data can be updated or reprogrammed. The
IPMI firmware stores the write protect state in it’s local NV-RAM.
Note: The write protection mode is still active when the payload is off even if the IPMI firmware re-
boots. To disable the write protection mode, set the DIP Switch SW2, switch 3, to OFF and
switch on the payload.
