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