Boot Sequence
Boot Sequence can be set to Diskette First (the default option), 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 try booting 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 tries to boot 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 attempt 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 try booting 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 tries to boot 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 <Ctrl> and the right-arrow key. Table 2 lists other navigation keys used on
the Device List screen.
