After specifying the boot mode, proceed to install your operating system from that mode. Thereafter, boot the system to the same boot mode (BIOS or UEFI) to access the installed operating system. Trying to boot the operating system from another boot mode will cause the system to halt immediately at startup.

Using the System Setup Program
and UEFI Boot Manager
The System Setup program is the BIOS program that enables you to manage
your system hardware and specify BIOS-level options. From the System Setup
program, you can:
•
Change the NVRAM settings after you add or remove hardware
•
View the system hardware configuration
•
Enable or disable integrated devices
•
Set performance and power management thresholds
•
Manage system security
Choosing the System Boot Mode
The System Setup program also enables you to specify the boot mode for
installing your operating system:
•
BIOS boot mode (the default) is the standard BIOS-level boot interface.
•
UEFI boot mode is an enhanced 64-bit boot interface based on Unified
Extensible Firmware Interface (UEFI) specifications that overlays the
system BIOS. See "Entering the UEFI Boot Manager" on page 72 for more
information on this interface.
You must select the boot mode in the
Boot Mode
field of the "Boot Settings
Screen" on page 65 of the System Setup program. After specifying the boot
mode, proceed to install your operating system from that mode. Thereafter,
boot the system to the same boot mode (BIOS or UEFI) to access the
installed operating system. Trying to boot the operating system from another
boot mode will cause the system to halt immediately at startup.
NOTE:
Operating systems must be UEFI-compatible (for example, Microsoft
®
Windows Server
®
2008 x64 version) to be installed from the UEFI boot mode. DOS
and 32-bit operating systems do not support UEFI and can only be installed from the
BIOS boot mode.
