22 : BIOS vs. UEFI | Doc ID 20444677 | June 2018
Since the integrated device firmware supports both UEFI and BIOS boot modes, it is not necessary to update
the firmware for one boot mode or the other. When the system is in UEFI boot mode, the BIOS automatically
loads UEFI drivers for the devices instead of traditional option ROMs.
RAID containers and virtual disk configurations do not require re-configuration when the system is changed to
UEFI boot mode. The RAID metadata is independent of the system boot mode.
