1.10.1.3.3 AGP Add-in Card Support
AGP is a high-performance interface for graphics-intensive applications, such as 3D applications.
While based on the PCI Local Bus Specification, Rev. 2.1, AGP is independent of the PCI bus and
is intended for exclusive use with graphical display devices. AGP overcomes certain limitations of
the PCI bus related to handling large amounts of graphics data with the following features:
• Pipelined memory read and write operations that hide memory access latency
• Demultiplexing of address and data on the bus for nearly 100 percent efficiency

1.10.2 Intel 815EP Graphics Subsystem
✏
NOTE
Install memory in the DIMM sockets prior to installing the AGP video card to avoid interference
with the memory retention mechanism.
The Intel 815EP chipset, used on the D815EPEA2 board, provides an AGP universal connector
which supports a 1x, 2x, or 4x AGP add-in card with either 3.3 V or 1.5 V I/O.
