Set the BIOS Boot Mode

The BIOS firmware supports both legacy BIOS and Unified Extensible Firmware Interface (UEFI); the default setting is Legacy. Some operating systems support both legacy BIOS and UEFI BIOS and some support legacy BIOS only.

The following supported Microsoft Windows operating systems support UEFI or legacy BIOS boot modes:

• Microsoft Windows Server 2008 R2 SP1

• Microsoft Windows Server 2012

• Microsoft Windows Server 2012 R2
