will be initialized. The first hard-disk drive in the list becomes the bootable drive C.

Boot Sequence enables you to set the order of the devices from which the system
attempts to boot.
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.
To set the boot device order, press <Enter> to access the field’s pop-up options
menu. Use the up- and down-arrow keys to move through the list of devices. Press
<Enter> to enable or disable a device (enabled devices appear with a check mark).
Press plus (+) or minus (–) to move a selected device up or down the list. The
following sections detail typical devices.

Selecting Diskette Drive A: as the first device 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 next device in the
boot sequence list.

Selecting Hard-Disk Drive causes the system to attempt to boot first from the
hard-disk drive and then from the next device in the boot sequence list.
