Motherboard Description
System and video BIOS shadow RAM
Plug-and-Play (PnP) BIOS feature
A built-in PS/2 style keyboard connector and a built-in PS/2 compatible
mouse connector
Two serial ports (one built-in connector and one optional pin header) and one
built-in parallel port
The following are manufacturing options:
Wake up LAN connector
Wake up Ring connector
Management extension hardware
Chassis security connector
System fan controller connector
TheAccelerated Graphics Port(A.G.P.) isahigh-performance
interconnect for graphic-intensive applications, such as 3D
applications.A.G.P.is independent ofthe PCI busand is intended
for exclusive use with graphical-display devices.
The motherboard has two USB ports; one USB peripheral can be
connected to each port. For more than two USB devices, an external
hub can be connected to either port. The motherboard fully supports
the universal host controller interface (UHCI) and uses
UHCI-compatiblesoftwaredrivers.
