7.3BOOT 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 can, if configured with a NIC with Preboot Execution Environment (PXE) option ROM, boot with a NetPC-compliant server.
