Use systemboard jumper
NOTE: System-board jumper is available only on desktop computers.
Almost all system boards on desktop computers contain a jumper to clear CMOS settings along with the BIOS password. The
location of this jumper varies depending upon the system board. Look for the jumpers near the CMOS battery, usually labeled as
CLR, CLEAR, CLEAR CMOS, and so on.
For procedure on clearing passwords and clearing CMOS settings, see your computer Service Manual at www.dell.com/support.
Boot Sequence
Boot Sequence allows you to bypass the System Setupdefined 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 (if available)
SATA Hard Drive (if available)
Diagnostics
NOTE: Choosing Diagnostics, will display the ePSA diagnostics screen.
The boot sequence screen also displays the option to access the System Setup screen.
