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.

share|improve this question the manual may be of help here. There's apparently USB headers. This is a really old system. Kinda odd that it uses AT connectors rather than PS/2 since they were common way before then. – Journeyman Geek Oct 26 '12 at 4:59

Have a look at this:

It looks like that there may be USB connectors.

Best of luck
