Legacy BIOS Boot Mode and UEFI Boot Mode
The server is equipped with a Unified Extensible Firmware Interface (UEFI), which can be
configured to support either UEFI or Legacy BIOS Boot Mode. Legacy BIOS is the default
boot mode, and should be used with software and adapters that do not have UEFI drivers.
When you change the server boot mode, the change takes effect at the next server reset. If
you intend to switch boot modes, you should back up the current UEFI configuration. For
instructions on backing up current firmware configurations, see “Backing Up Current Firmware
and Hardware Configurations” on page 101 .
Typically, you set the boot mode only once, before you install an operating system (OS) on
the server. If you change the boot mode after you have installed an OS, the OS will not boot.
Review the OS installation guide to determine whether the OS you intend to install supports
UEFI Boot Mode.
The advantages of UEFI Boot Mode include:
■
Faster boot time.
