I have a BIW1B ver 1.0 mother board with 5 pin DIN key board Port. But now it is not working. I replaced a new port and soldered it back. Still no response. It does not have any ps/2 port or usb port. may be some connector on the board, but I could not locate it. But there is a serial port to use serial mouse. Can we use this serial port for both ps/2 KB & MS. Please guide me.
Have a look at this:
It looks like that there may be USB connectors.
Best of luck
