As someone stated, you may have to change the BIOS to set the correct type of
parallel port. Also, I noted that the LPT port pinout on the k1ea website says
that pin 11 is ground. I looked at it the other day and it wasn't. Maybe one
version of the software sets or resets that bit to ground and one doesn't. If
your interface uses pin 11, you might want to switch to some other ground pin,
such as 18.
