NOTE
The Desktop Boards D845EPT2 and D845EBG2 are 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. The boxed desktop board comes
with an integrated AGP card retention mechanism (RM). For information about installing the
AGP card, see Chapter 2 on page 21.
Communication and Networking Riser (CNR) (Optional)
The optional CNR provides an interface that supports various features such as audio, modem,
and LAN.
BIOS
The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the PCI and IDE
auto-configuration utilities. The BIOS is stored in the Firmware Hub.
The BIOS can be updated by following the instructions in Chapter 3 on page 37.
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.
