I am not sure, but I would expect that you would need BIOS support for
something like that.  Personally, I would stick with serial ports as
long as possible, because they are much more simple than any

What do you hook up to that serial port, anyway?

Sorry I can't be more helpful, but I wanted to make sure you got
*some* help.

Good luck.
