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.
