4.3.8 BIOS recovery
It is unlikely that anything will interrupt a BIOS update; however, if an interruption occurs, the BIOS could be damaged. The following

made bootable.

4.3.9 Boot options
In the BIOS Setup program, the user can choose to boot from a SATA optical drive, hard drive, USB drive, USB flash drive, USB Floppy
drive, or the network. The default setting is for the SATA optical drive to be the first boot device, the hard drive second, and a
removable drive third (such as USB drive, USB flash or USB floppy drive) and the network last.
NOTE
Optical devices, USB devices and network will only appear in the boot menu if they are enabled.
4.3.9.1 SATA optical drive boot
Booting from optical drive is supported in compliance to the El Torito bootable CD/DVD format specification. Under the Boot menu in
the BIOS Setup program, a SATA optical drive is listed as a boot device. Boot devices are defined in priority order. Accordingly, if there
is no bootable CD or DVD in the optical drive, the system will attempt to boot from the next defined drive.
4.3.9.2 Network boot
The network can be selected as a boot device. This selection allows booting from the onboard LAN or a network add-in card with a
remote boot ROM installed. Pressing the <F8> key during POST will display the boot device menu, then choose "PXE IPv4 Intel (R)
Ethernet Connection ... " to force booting from the LAN. To use this key during POST with a user password set, the User Access Level
in the BIOS Setup program's Security menu must be set to Full Access and the boot to Network option in the BIOS Setup prog
ram’s
Boot menu must be enabled.
4.3.9.3 Booting without attached devices
For use in embedded applications, the BIOS has been designed so that after passing the POST, the operating system loader is invoked
even if the following devices are not present:
• Video adapter
• Keyboard
• Mouse
