BIOS 
The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the PCI and IDE 
auto-configuration utilities, and the video BIOS.  The BIOS is stored in the firmware hub. 
The BIOS can be updated by following the instructions in Chapter 3 on page 45. 
PCI Auto Configuration 
If you install a PCI add-in card in your computer, the PCI 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 add-in card. 
IDE Auto Configuration 
If you install an IDE device (such as a hard drive) in your computer, the IDE 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 an IDE device.  You can override the 
auto-configuration options by specifying manual configuration in the BIOS Setup program. 
To use ATA-66/100 features, the following items are required: 
•  An ATA-66/100 peripheral device 
•  An ATA-66/100 compatible cable 
•  ATA-66/100 operating system device drivers 
Security Passwords 
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 
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.
