Chapter 7 BIOS ROM

7.3 BOOT

FUNCTIONS

The BIOS supports various functions related to the boot process, including those that occur during
the Power On Self-Test (POST) routine.

7.3.1 BOOT DEVICE ORDER


The default boot device order is as follows:

1. CD-ROM drive (EL Torito CD images)
2. Diskette drive (A)
3. Hard drive (C)
4. Network boot

The order can be changed in the ROM-based Setup utility (accessed by pressing F10 when so
prompted during POST).

7.3.2 NETWORK BOOT (F12) SUPPORT


The BIOS supports booting the system to a network server. The function is accessed by pressing
the F12 key when prompted at the lower right hand corner of the display during POST. Booting to
a network server allows for such functions as:



Flashing a ROM on a system without a functional operating system (OS).
Installing an OS.
Installing an application.

These systems include, as standard, an integrated Intel 82562-equivalent NIC with Preboot
Execution Environment (PXE) ROM and can boot with a NetPC-compliant server.
