Boot Sequence
This feature allows users to change the sequence of devices from which the computer boots.
Option Settings
l Normal — (Available only for the current boot process.) The computer attempts to boot from the sequence of devices specified in system setup.
l Diskette Drive — The computer attempts to boot from the floppy drive. If the floppy disk in the drive is not bootable, or if no floppy disk is in the drive,
the computer generates an error message.
l Hard Disk Drive C: — The computer attempts to boot from the primary hard drive. If no operating system is on the drive, the computer generates an
error message.
l CD Drive — The computer attempts to boot from the CD drive. If no CD is in the drive, or if the CD has no operating system, the computer generates an
error message.
l Integrated NIC — As the computer boots, it prompts you to press <Ctrl><Alt><b>. Pressing this key combination causes a menu to display 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 computer attempts to boot from
the next device in the boot sequence list.
l USB Flash Device — Insert the key into a USB port and restart the computer. When F12 = Boot Menu appears in the upper-right corner of the screen,
press <F12>. The BIOS detects the key and adds the USB key option to the boot menu.
Changing the Computer Boot Sequence for the Current Boot

from the hard drive when the diagnostic tests are complete.
