Sata Auto Configuration; Pci*/Pci Express Auto Configuration; Bios Security Passwords - Intel DQ67OW Product Manual

Intel Desktop Board DQ67OW Product Guide

SATA Auto Configuration

If you install a SATA device (such as a hard disk drive) in your computer, 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
SATA device. You can override the auto-configuration options by specifying manual
configuration in the BIOS Setup program.

PCI*/PCI Express Auto Configuration

If you install a Conventional PCI or PCI Express add-in card in your computer, 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 Conventional PCI or
PCI Express add-in card.

BIOS 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.
For instructions on resetting the password, go to Clearing Passwords on page 60.
