Using the System Setup Program 2-7
Diskette First
Selecting Diskette First causes the sy s t e m t o t r y
booting from drive A first. If the system finds a dis-
kette that is not bootable in the drive or finds a
problem with the drive itself, it displays an error mes-
sage. 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, 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.
The Device List screen (see Figure 2-2) provides three
categories for listing and prioritizing the available boot
devices on your system:
•Boot Device Priority
•Exclude From Boot Device Priority
•Device Controller Priority
The Boot Device Priority category lists all bootable
devices (hard-disk drives, CD-ROM drives, and so on)
that are controlled by the system BIOS and any Plug and
Play network adapters installed in the system.
The Exclude From Boot Device Priority category allows
you to remove from the Boot Device Priority category
any boot devices that you want the system to ignore dur-
ing system start-up.
The Device Controller Priority category lists the system
BIOS controller; any non-Plug and Play devices, such as
network adapter cards; and any secondary controller
cards, such as a small computer system interface (SCSI)
adapter, installed in the system.
NOTE: Non-Plug and Play devices appear in this list as
Adapters without ID support.
When determining the order of devices to boot from, the
system first considers the order of the devices listed
under the Device Controller Priority category, then the
order of devices under Boot Device Priority.
To specify your priority preferences, order the devices
under these categories so that the highest-priority con-
troller is at the top of the Device Controller Priority
category and the highest-priority device is at the top of
the Boot Device Priority category. Order the remainder of
the devices in the Boot Device Priority category accord-
ing to your preferences. Move any devices that you want
the system to ignore during start-up into the Exclude
From Boot Device Priority category.
NOTE: The system defines drive C in the Boot Device
Priority category as the first hard-disk drive attached to
the highest-priority device controller. Therefore, if you
have a SCSI adapter installed in your system and you
want the SCSI drive 0 to be drive C, you must move the
SCSI adapter item to the top of the Device Controller Pri-
ority category.
To change the order of the devices, press <Ctrl> and the
up- or down-arrow key. If you want to revert to the
original Boot Device Priority category settings, press
<Ctrl><Del>.
NOTE: If you exit the Device List option by pressing
<Esc> or <Alt><b> without making any changes, the
Boot Sequence category is set to the Device List option.
CAUTION: Only a technically knowledgeable person
should change the settings in the Device List screen.
