7.2.1 Configuration Utility

The Configuration Utility (CU) provides the means to configure on-board hardware devices and
add-in cards. The CU consists of the standard PC-AT Setup utility (a.k.a. Setup), embedded in
Flash ROM, for configuration of on-board resources.

7.2.2 CMOS Configuration RAM Summary

The SuperI/O FDC37B782 chip on the baseboard contains battery-backed CMOS memory for
system hardware setup parameters.

7.2.3 Flash Memory Update Utility

The system BIOS is resident in partitioned Flash ROM. The device is in-circuit reprogrammable,
except for the recovery boot block, which is electrically protected from erasure.
To reload Flash memory, use a Flash update utility. The board ID must match with the one in the
load file or the utility will not reprogram the Flash. This prevents the utility from reprogramming
the Flash with BIOS for another platform. For more information, see Section 8 for information on
the Flash memory update utility.

7.2.4 Fail-Safe BIOS Extensions

The Fail-Safe BIOS extensions allow a remote user to diagnose and fix problems on a machine
which has not successfully booted the OS. The centerpiece of the Fail-Safe extensions is the
Emergency BIOS Console . The Emergency BIOS Console is a Flash ROM-resident utility that
redirects input and output over a serial or modem connection. This console is only available when
the system is set for "Appliance" mode via jumper J16 on the motherboard. For further
information see the section entitled Jumper Blocks.

7.2.5 System Flash ROM Layout

The Flash ROM contains system initialization routines and runtime support routines. The exact
layout is subject to change. All areas are 64 KB in size (symmetric flash). The complete ROM is
visible, starting at physical address 4 GB less 1 MB. The Flash Memory Update utility loads
BIOS components to blocks of specified length and location. None of the blocks are visible at the
aliased addresses below 1 MB due to shadowing. The BIOS alone needs to know the exact Flash
map. Intel reserves the right to change the Flash map without notice. All blocks in this flash part
are 64k (10000h) in length. The BIOS will adjust the size of each component to fit in a given
block.
