USB(Universal Serial Bus) Ports and USB 2/3 Connector (CN11)
If you want to use a USB keyboard, you must
enable the USB keyboard support function in
BIOS's Integrated Peripherals menu (See Section
3-4). 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.
This board contains a USB Host controller and
includes a root hub with two USB ports (meets
USB Rev 1.0 spec.) and a connector for optional
USB Adaptor (USB2/3). Four USB peripherals or
hub devices are able to be connected.
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.
CPU Clock Ratio Jumper (JP9/JP10/JP11/JP12)
Set the clock ratio according to your processor's
specification.
