8.3 BOOT FUNCTIONS
The BIOS supports various functions related to the boot process, including those that occur during
the Power On Self-Test (POST) routine.
8.3.1 BOOT DEVICE ORDER
The default boot device order is as follows:
1. IDE CD-ROM drive (EL Torito CD images)
2. Diskette drive (A)
3. MultiBay device (A: or CD-ROM) if applicable
4. USB device
5. Hard drive (C)
6. Network interface controller
The order can be changed in the ROM-based Setup utility (accessed by pressing F10 when so
prompted during POST). Entries are displayed only if the actual device is attached, with the
exception of the USB device, which is always displayed even if a USB storage device is not
present. The hot IPL option is available through F9 during the POST routine. The order defined
by the Setup (F10) can be overridden once by pressing the F9 key during the boot process.
8.3.2 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:
