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 Drive — 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 PXE — (Available only for the future boot process) As the computer boots, it prompts the user 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 system attempts to boot from the next device in the boot sequence list.
l USB Flash Device — Insert the memory device 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 device and adds the USB flash option to the boot menu.
