Cisco UCS Manager pushes BIOS configuration changes through a BIOS policy or default BIOS settings
to the Cisco Integrated Management Controller (CIMC) buffer. These changes remain in the buffer and
do not take effect until the server is rebooted.
We recommend that you verify the support for BIOS settings in the server that you want to configure.
Some settings, such as Mirroring Mode and Sparing Mode for RAS Memory, are not supported by all
Cisco UCS servers.
Note
Main BIOS Settings
The following table lists the main server BIOS settings that you can configure through a BIOS policy or the
default BIOS settings:

When the server is rebootedafter youchange oneor more BIOS
settings.
If you enable this setting, the server is rebooted according to
the maintenance policy in the server's service profile. For
example, if the maintenance policy requires user
acknowledgment, the server is not rebooted and the BIOS
changes are not applied until a user acknowledges the pending
activity.
If you do not enable this setting, the BIOS changes are not
applied until the next time the server is rebooted, whether as a
result of another server configuration change or a manual reboot.
