Intel Desktop Boards D865GRH Product Guide

Accelerated Graphics Port (AGP)

NOTE

Desktop Board D865GRH is only compatible with 0.8 V and 1.5 V AGP cards.

The AGP connector is keyed for 0.8 V and 1.5 V AGP cards only; the connector is not mechanically compatible with legacy 3.3 V AGP cards. Do not attempt to install a legacy 3.3 V AGP card.

AGP is a high-performance interface for graphics-intensive applications, such as 3D graphics. AGP is independent of the PCI bus and is intended for exclusive use with graphical display devices.

The AGP 3.0 connector supports 8x, 4x, and 1x AGP cards.

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 53.

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.
