Boot Device Priority Submenu of the Boot Menu
The Boot Device Priority Submenu is for setting the order for checking of sources for the operating system.

■
Be aware of the operating environment when booting from a CD-ROM/DVD-ROM or you may over-
write files by mistake.
■
A bootable CD-ROM/DVD-ROM has either a floppy disk format or a hard drive format. When the boot-
able CD-ROM/DVD-ROM is used, the drive allocations change automatically without changing the BIOS
setup. If a floppy disk format is used, the CD-ROM/DVD-ROM becomes Drive A. The CD-ROM/DVD-
ROM will only take drive C: (hard drive format) if the internal hard drive is not present or is disabled. The
bootable CD-ROM/DVD-ROM can never use a C: designation if a formatted internal hard drive is
present since the C: designator is always reserved for the internal hard drive. The boot sequence ignores
the new drive designations, however, your application software will use the new designations.

The boot selections determine the order in which the BIOS searches for the operating system during a startup
sequence. To change the order, highlight one source by using the [up] or [down] cursor keys and then press
the [PgUp] or [PgDn] key to change the order number. “Network Boot” appears only when Pre-Boot
Execution Environment is enabled.
NOTE: Be aware that if you use the CD-ROM drive as the first boot device, certain files may be overwritten,
depending upon your operating environment.
