Desktop Board Features

Expansion Slots

Desktop Board D845PESV has the following add-in card connectors:

•Six PCI bus add-in card connectors (SMBus routed to PCI bus connector 2)

•One AGP connector

Accelerated Graphics Port (AGP)

✏NOTE

Desktop Board D845PESV is only compatible with 1.5 V AGP cards.

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 connector supports 1.5 V AGP 4X and 2X add-in 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 39.

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
