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 and Network 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.
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.

3.8.2 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
3.9 Fast Booting Systems with Intel
These factors affect system boot speed:
Selecting and configuring peripherals properly
Using an optimized BIOS, such as the Intel

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.
