Intel Desktop Board D975XBX Product Guide

PCI and PCI Express* Auto Configuration

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.

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 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.

Chassis Intrusion

The desktop board supports a chassis security feature that detects if the chassis cover has been removed. The security feature uses a mechanical switch on the chassis that can be connected to the chassis intrusion header on the desktop board. See Figure 28 on page 48 for the location of the chassis intrusion header.

Power Management Features

Power management is implemented at several levels, including:

•Advanced Configuration and Power Interface (ACPI)

•Hardware support:

⎯Fan connectors

⎯Suspend to RAM (Instantly Available PC technology)

⎯Resume on Ring

⎯Wake from USB

⎯Wake from PS/2 keyboard/mouse
