IDE operating modes:
1.10 Keyboard, Mouse and USB Interface
PS/2 keyboard, PS/2 mouse, and USB connectors are located on the
back panel of the P6F104 mainboard. The 5V line to the PS/2
Keyboard and PS/2 Mouse connectors are protected with a
PolySwitch circuit that acts like a self-healing fuse which will re-
establishing the connection after an over-current condition is
removed. While this device eliminates the possibility of replacing
fuse, you still need to be sure to turn off the system power before
connecting or disconnecting a keyboard or a mouse.
The P6F104 mainboard has a dual USB connector to support two
USB ports. The USB is a serial bus interface standard that is
designed to bring the “Plug and Play” concept to the outside of the
computer system chassis. The bus allows devices to be attached,
configured, used and detached while the host system is in operation.
The USB will allow as many as 63 devices to be daisy chained in
any combination per port. With up to 12Mbits/sec transfer rate, USB
is suitable for devices such as keyboard, mouse, digital joystick,
game pad, fax/modem, scanner, printer, ISDN and telephony device.
