another BIOS update is performed. If a flash failure occurs, the BMC will switch back to the 
BIOS on the other partition, thus affecting a “Roll Back” as mentioned above.  
  
Unlike IFLASH / On-line updates, a recovery method will continue to change the BIOS on the 
primary partition. 
 
6.20  BIOS and System Setup 
Two utilities are used to configure the BIOS and system resources, the BIOS Setup utility and 
the System Setup Utility. On-board devices are configured with the BIOS Setup utility that is 
embedded in flash ROM. BIOS Setup provides enough configuration functionality to boot an 
operating system image or a CD-ROM containing the System Setup Utility. The System Setup 
Utility is used to configure the IRQ assignments on PCI add-in cards. The System Setup Utility 
is released on diskette or CD-ROM. The BIOS Setup Utility is always provided in flash for basic 
system configuration. 
The configuration utilities allow the user 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. 
6.20.1 
BIOS Setup Utility 
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 on-
board resources. The System Setup Utility must be used for configuring the on-board devices 
and add-in cards.  
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: 
• 
Embedded SCSI 
• 
Embedded video  
• 
Each embedded NIC (2) 
• 
Embedded ATA RAID 
• 
ICH3 USB Controller 
Note: The BIOS options described in this section may or may not be present in pre-production 
versions of the system BIOS. This section describes the BIOS utility as it is planned to be at 
production and is subject to change. Option locations in a given menu of the BIOS setup utility 
as described in this section may be different from those observed on any one pre-production 
version of the system BIOS.
