3.8.2
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 <F12> key during POST automatically forces boot from the LAN.
3.8.3
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
3.8.4
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 (as set in the BIOS setup program
’
s Boot Device Priority
Submenu).
Table 21 lists the boot device menu options.

3.9 Fast Booting Systems with Intel
®
Rapid BIOS Boot
These factors affect system boot speed:
•
Selecting and configuring peripherals properly
•
Using an optimized BIOS, such as the Intel Rapid
®
BIOS
3.9.1
Peripheral Selection and Configuration
The following techniques help improve system boot speed:
•
Choose a hard drive with parameters such as
“
power-up to data ready
”
less than eight seconds,
that minimize hard drive startup delays.
•
Select a CD-ROM drive with a fast initialization rate.
This rate can influence POST
execution time.
•
Eliminate unnecessary add-in adapter features, such as logo displays, screen repaints, or mode
changes in POST.
These features may add time to the boot process.
•
Try different monitors.
Some monitors initialize and communicate with the BIOS more
quickly, which enables the system to boot more quickly.
