Updating the BIOS and Cisco IMC Firmware
When you upgrade the BIOS firmware, you must also upgrade the Cisco IMC firmware to the same version
or the server does not boot. Do not power off the server until the BIOS and Cisco IMC firmware are
matching or the server does not boot.
Cisco provides the Cisco Host Upgrade Utility to assist with simultaneously upgrading the BIOS, Cisco
IMC, and other firmware to compatible levels.
Caution
The server uses firmware obtained from and certified by Cisco. Cisco provides release notes with each firmware
image. There are several possible methods for updating the firmware:
•
Recommended method for firmware update: Use the Cisco Host Upgrade Utility to simultaneously
