Boot Sequence
This feature allows you to change the boot sequence for devices.
Option Settings
•
Diskette Drive —
The computer attempts to boot from the floppy drive. If the floppy disk in
the drive is not bootable, if no floppy disk is in the drive, or if there is no floppy drive installed
in the computer, the computer generates an error message.
•
Hard Drive
— The computer attempts to boot from the primary hard drive. If no operating
system is on the drive, the computer generates an error message.
•
CD Drive
— The computer attempts to boot from the CD drive. If no CD is in the drive, or
if the CD has no operating system, the computer generates an error message.
•
USB Flash Device —
Insert the memory device into a USB port and restart the computer.
When
F12 = Boot Menu
appears in the upper-right corner of the screen, press <F12>. The
BIOS detects the device and adds the USB flash option to the boot menu.
NOTE: To boot to a USB device, the device must be bootable. To make sure that your device is bootable,
check the device documentation.
Changing Boot Sequence for the Current Boot
You can use this feature, for example, to tell the computer to boot from the CD drive so that you
can run the Dell Diagnostics on the
Dell Dimension ResourceCD
, but you want the computer to
boot from the hard drive when the diagnostic tests are complete. You can also use this feature to
restart your computer to a USB device such as a floppy drive, memory key, or CD-RW drive.
NOTE: If you are booting to a USB floppy drive, you must first set the floppy drive to OFF in system setup
(see page 113).
