The desktop board supports the following: 
•  One PCI Express x16 add-in card 
•  One PCI Express x4 add-in card (routed to the physical x16 connector)  
•  One PCI Express x1 add-in card 
•  Four PCI bus add-in cards 

For information about installing the PCI Express x16 card, see page 37 in Chapter 2. 

The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the PCI and IDE 
auto-configuration utilities, and the video BIOS.   
See Chapter 3 on page 59 for more information about the BIOS. 

If you install a Serial ATA or IDE device (such as a hard drive) in your desktop board, the auto-
configuration utility in the BIOS automatically detects and configures the device for your computer.  
You do not need to run the BIOS Setup program after installing a Serial ATA or IDE device.  You 
can override the auto-configuration options by specifying manual configuration in the BIOS Setup 
program. 
When booting from a Serial ATA device, Serial ATA connector 0 is the first boot device and Serial 
ATA connector 3 is the last boot device by default. 

If you install a PCI/PCI Express add-in card in your desktop board, the PCI/PCI Express auto-
configuration utility in the BIOS automatically detects and configures the resources (IRQs, DMA 
channels, and I/O space) for that add-in card.  You do not need to run the BIOS Setup program after 
you install a PCI/PCI Express add-in card. 

The BIOS includes security features that restrict whether the BIOS Setup program can be accessed 
and who can boot the computer.  A supervisor password and a user password can be set for the 
BIOS Setup and for booting the computer, with the following restrictions:   
•  The supervisor password gives unrestricted access to view and change all Setup options.  If 

only the supervisor password is set, pressing <Enter> at the password prompt of Setup gives 
the user restricted access to Setup. 

•  If both the supervisor and user passwords are set, you must enter either the supervisor 

password or the user password to access Setup.  Setup options are then available for viewing 
and changing depending on whether the supervisor or user password was entered. 

•  Setting a user password restricts who can boot the computer.  The password prompt is 

displayed before the computer is booted.  If only the supervisor password is set, the computer 
boots without asking for a password.  If both passwords are set, you can enter either password 
to boot the computer.
