3.7 Boot Options
In the BIOS Setup program, the user can choose to boot from a hard drive, removable drive, or the
network. The default setting is for the hard drive to be the first boot device, the removable drive
second, and the network third.
3.7.1 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 <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.
3.7.2 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
3.7.3 Changing the Default Boot Device During POST
Pressing the <F10> key during POST causes a boot device menu to be displayed. This menu
displays the list of available boot devices. Table 33 lists the boot device menu options.
