Complete The Operating System Setup
To install an operating system for the first time, see the installation and configuration documentation for your operating
system. Be sure that the operating system is installed before installing hardware or software not purchased with the
system.
Supported Operating Systems
The following operating systems are supported:
• Microsoft Windows Server 2012
10
• Red Hat Enterprise Linux 6.5 and later
NOTE: For latest information on supported operating systems, see dell.com/ossupport.
Other Information You May Need
WARNING: See the safety and regulatory information that shipped with your system. Warranty information may be
included within this document or as a separate document.
• The Owner’s Manual provides information about system features and describes how to troubleshoot the system and
install or replace system components. This document is available online at www.dell.com/poweredgemanuals.
• Any media that ships with your system that provides documentation and tools for configuring and managing your
system, including those pertaining to the operating system, system management software, system updates, and
system components that you purchased with your system.
• For latest information on supported operating systems, see dell.com/ossupport.
NOTE: Always check for updates on dell.com/support/manuals and read the updates first because they often
supersede information in other documents.
NOTE: When upgrading your system, it is recommended that you download and install the latest BIOS, driver, and
systems management firmware on your system from dell.com/support.

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.
<F12> Enters the Boot Manager.
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
From the Boot Manager, you can:
• Verify the boot mode and the secure boot status
• Select a one-time boot device
• Perform hardware diagnostics
• Configure the Intel Management Engine BIOS Extension
• Update the BIOS
2
Choosing The System Boot Mode
System Setup enables you to specify the boot mode for installing your operating system:
• Legacy 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.
In System Setup, select boot mode in the Boot List Option field of the Boot Sequence screen. Once you specify the boot
mode, the system boots in the specified boot mode and then proceeds to install your operating system from that mode.
Thereafter, you must boot the system in the same boot mode (Legacy 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.
NOTE: Operating systems must be UEFI-compatible 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 Legacy boot mode.
NOTE: For the latest information on supported operating systems, go to dell.com/ossupport.
