Infrared Connector (IR1)
If you enable the COM2 Mode in BIOS's Integrated
Peripherals menu the COM2 port will support IR
functions. (See section 3-8)
PS/2 Mouse and Keyboard Ports
If a PS/2 mouse is used, BIOS will automatically
detect and assign IRQ12 to the PS/2 mouse.
USB(Universal Serial Bus) Ports
If you want to use a USB keyboard, you must
enable the USB keyboard support function in
BIOS's Integrated Peripherals menu (See Section
3-8). USB is an open industry standard, providing
a simple and inexpensive way to connect up to
125 devices to a single computer port. Keyboards,
mice, tablets, digitizers, scanners, bar-code readers,
modems, printers and many more can all be used
at the same time.
USB is a dynamically reconfigurable serial bus
with an elementary data rate of 12Mbps. Based
on off the shelf, low cost micro-controller
technology, its modular layered software protocol
supports sophisticated devices and application
programs.
This board contains a USB Host controller and
includes a root hub with two USB ports (meets
USB Rev 1.0 spec.). Two USB peripherals or hub
devices are able to be connected.
