Changing the Boot Sequence
The boot sequence allows you to specify the order of the devices from which the system attempts to boot.
1. Press <Enter> to access the Boot Sequence option's pop-up menu.
2. Press the up- and down-arrow keys to move through the list of devices.
3. Press the spacebar to enable or disable a device (enabled devices appear with a check mark).
4. Press plus (+) or minus (–) to move a selected device up or down the list.
Option settings:
l Diskette Drive A: — The system attempts to boot from the diskette drive. If the system finds a diskette in the drive that is not bootable, an error
message appears. If no diskette is in the drive, the system attempts to boot from the next device in the list.
l Hard Drive — The system attempts to boot from the primary hard drive. If the system does not find an operating system on the drive, it attempts to
boot from the next device in the list.
l CD-ROM Device — The system attempts to boot from the CD drive. If the system does not find a CD in the drive or if there is not an operating system
on the CD, the system attempts to boot from the next device in the list.
l MBA (Onboard NIC) — The system prompts you to press <Ctrl><Alt><b> at the Dell logo screen during boot. A menu appears that allows you to select
a method for booting from a network server. If a boot routine is not available from the network server, the system attempts to boot from the next
device in the list.
