Intel Desktop Board DH61WW 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 52.

Trusted Platform Module (TPM) Support

Intel Desktop Board DH61WW provides a header to connect to an external TPM. The

header is shown in Figure 1, P on page 12 and the header pinout is listed in Table 8 on

page 45. TPMs are designed to enhance platform security by providing a

protected

space for key operations and other security critical tasks. Using both hardware and

software, the TPM protects encryption and signature keys at their most vulnerable

stages—operations when the keys are being used unencrypted in plain-text form.

TPMs shield unencrypted keys and platform authentication information from software-

based attacks.
