Boot Sequence
Boot Sequence can be set to Diskette First (the default), Hard Disk Only, CD-ROM First, or Device List.
The term boot refers to the system's start-up procedure. When turned on, the system "bootstraps" itself into
an operational state by loading into memory a small program, which in turn loads the necessary operating
system. Boot Sequence tells the system where to look for the files that it needs to load.
Diskette First
Selecting Diskette First causes the system to boot from drive A first. If the system finds a diskette that is not
bootable in the drive or finds a problem with the drive itself, it displays an error message. If it does not find a
diskette in the drive, the system boots from the hard-disk drive (drive 0), then from the CD-ROM drive, and
finally from the Plug and Play network adapters in the order found.
Hard Disk Only
Selecting Hard Disk Only causes the system to boot first from the hard-disk drive and then from the Plug and
Play network adapters in the order found.
CD-ROM First
Selecting CD-ROM First causes the system to boot from the CD-ROM drive first. If the system finds a CD
that is not bootable in the drive or finds a problem with the drive itself, it displays an error message. If it does
not find a CD in the drive, the system boots from drive A, then from drive C, and finally from the Plug and
Play network adapters in the order found.
Device List
Device List provides access to the Device List screen, where you can choose from a list of available boot
devices to boot from and specify the order in which your computer attempts to boot from these devices. To
view the Device List screen, press
