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.
• Unified Extensible Firmware Interface (UEFI) boot mode is an enhanced
64-bit boot interface based on UEFI specifications that overlays the
system BIOS. For more information on this interface, see "Entering the
UEFI Boot Manager" on page 51.
Select the boot mode in the Boot Mode field of the Boot Settings screen of
the System Setup program. See "Boot Settings Screen" on page 45. After the
system boots in the specified mode, 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 the other boot mode causes the system to halt immediately at startup.
