Video Port
The main and front panel boards provide a video port interface with a standard VGA-compatible, 15-pin
connector. Only one port is enabled at a time through auto detection of a connected monitor. Onboard
video is supplied by an ATI Rage XL video controller with 8 MB of onboard video SDRAM.

Universal Serial Bus (USB) Interface
The main board provides a double-stacked USB port and the front panel board provides two single
USB port connectors. These built-in USB ports permit the direct connection of four USB peripherals
without an external hub. If more devices are required, an external hub can be connected to either of
the built-in ports.
