System Setup
System Setup enables you to manage your computer hardware and specify BIOS level options. 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 your computer security
Boot Sequence
Boot Sequence allows you to bypass the System Setup‐defined boot device order and boot directly to a
specific device (for example: optical drive or hard drive). During the Power-on Self Test (POST), when the
Dell logo appears, you can:
• Access System Setup by pressing F2 key
• Bring up the one-time boot menu by pressing F12 key
The one-time boot menu displays the devices that you can boot from including the diagnostic option.
