3.8 Boot Options 
In the BIOS Setup program, the user can choose to boot from a diskette drive, hard drives,  
CD-ROM, or the network.  The default setting is for the diskette drive to be the first boot device, 
the hard drive second, and the ATAPI CD-ROM third.  The fourth device is disabled. 
3.8.1 CD-ROM 
Boot 
Booting from CD-ROM is supported in compliance to the El Torito bootable CD-ROM format 
specification.  Under the Boot menu in the BIOS Setup program, ATAPI CD-ROM is listed as a 
boot device.  Boot devices are defined in priority order.  Accordingly, if there is not a bootable CD 
in the CD-ROM drive, the system will attempt to boot from the next defined drive.

Pressing the <F12> key during POST automatically forces booting from the LAN.  To use this key 
during POST, the User Access Level in the BIOS Setup program’s Security menu must be  
set to Full.
