Dell DL2200 Using the System Setup Program and Uefi Boot Manager, Choosing the System Boot Mode

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.
