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. The boot-menu options are:

•

Removable Drive (if available)

•

STXXXX Drive

NOTE:

XXX denotes the SATA drive number.

•

Optical Drive

•

Diagnostics

NOTE:

Choosing Diagnostics, will display the ePSA diagnostics screen.

The boot sequence screen also displays the option to access the System Setup screen.

Navigation Keys

The following table displays the system setup navigation keys.

NOTE:

For most of the system setup options, changes that you make are recorded but do not take effect until you re-

start the system.
