Using The System Setup And Boot Manager

System Setup enables you to manage your system hardware and specify BIOS-level options. The following keystrokes provide access to system features during startup:

Keystroke Description

<F2> Enters the System Setup.

<F10> Enters System Services, which opens the Dell Lifecycle Controller 2 (LC2). The Dell LC2 allows you to access utilities such as embedded system diagnostics. For more information, see the Dell LC2 documentation.

<F11> Enters the BIOS Boot Manager or the Unified Extensible Firmware Interface (UEFI) Boot Manager, depending on the system's boot configuration.

<F12> Starts Preboot eXecution Environment (PXE) boot.

From the System Setup, 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

You can access the System Setup using the:

Standard graphical browser, which is enabled by default

Text browser, which is enabled using Console Redirection

To enable Console Redirection, in System Setup, select System BIOS Serial Communication screen Serial Communication, select On with Console Redirection.

NOTE: By default, help text for the selected field is displayed in the graphical browser. To view the help text in the text browser, you must press <F1>.

Choosing The System Boot Mode

System Setup 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.

You must select the boot mode in the Boot Mode field of the Boot Settings Screen of System Setup. Once you specify the boot mode, the system boots in the specified boot mode and you proceed then to install your operating system from that mode. Thereafter, you must boot the system in the same boot mode (BIOS or UEFI) to access the installed operating system. Trying to boot the operating system from the other boot mode will cause the system to halt at startup.
