This section describes the BIOS Setup Utility options. You can run BIOS Setup with or without an
operating system being present. Onboard devices are configured with the BIOS Setup utility that is
embedded in flash ROM.
The configuration utilities allow you to modify the CMOS RAM and NVRAM. The actual hardware
configuration is accomplished by the BIOS POST routines and the BIOS Plug-N-Play auto-configuration
manager. The configuration utilities update a checksum for both areas, so potential data corruption is
detected by the BIOS before the hardware configuration is saved. If the data is corrupted, the BIOS
requests that the user reconfigure the system and reboot.
Because the BIOS code is the most often changed part of the motherboard design, the
BIOS information described in this section may be a little different compared to the actual
BIOS that contained in your motherboard.

This section describes the ROM-resident setup utility that provides the means to configure the platform.
The BIOS Setup utility is part of the system BIOS and allows limited control over onboard resources.
The user can disable embedded PCI devices through the setup menus. When these devices are disabled
through setup, their resources are freed.
The following embedded devices can be disabled through setup menus, making them invisible to a
plug-and-play operating system that scans the PCI bus:
Network controllers embedded in nVIDIA MCP55Pro and IO 55 (For 2U)
Onboard VGA embedded in Pilot SMC
