See Section 2, “System Configuration,” for information on resetting the port through the BIOS
Setup Utility. See Section 9, “Specifications,” for the serial interface specifications.
Serial interface signals are output through the system board’s 9-pin, D-subconnector. The
connector is located at the rear of the system unit.
USB Interface
The Universal Serial Bus (USB) ports allow USB serial devices to be added without having to
open the system. One USB device can be plugged into each USB port for direct system
connection. With a hub and the proper cabling, up to 127 USB devices per port can be addressed
by the system.
The USB determines system resources for each peripheral and assigns them without user
intervention. Boot support for a USB keyboard is present so the system can be booted with a
USB keyboard instead of a standard keyboard.
Accelerated Graphics Port
The system board contains a direct integrated accelerated graphics port (Direct AGP) on the
system board that supports graphics-intensive, 3D applications. The Direct AGP supports
133-MHz data transfer rates, allowing 33 MB of data to be transmitted per second. The port is
connected to the VGA-compatible connector on the back of the system.
Connect a monitor to the board’s VGA connector on the back of the system.
Graphics Controller
The graphics controller, part of the Intel 82810E chipset, is specifically designed for graphics-
intensive operations, including 3D and 2D effects, texture mapping, text and color pixel
amplification, and video acceleration. The controller minimizes bus traffic by off-loading the
tasks normally performed by the processor, providing 64-bit, high resolution performance for
demanding True Color displays and other sophisticated graphics functions.
Motion Video Controller
The motion video controller on the 82810E chipset integrates a Windows graphical user
interface (GUI) engine and motion video playback hardware. Features include:
!
Hardware Motion Compensation to improve soft DVD video quality
!
MPEG-2 for lifelike video and audio.
