The simple answer is to change the I/O address in your CMOS on the LPT1
port to something other than 378.  If this is not possible in your CMOS or it
will not stay changed, sometimes Windows will reset a CMOS setting for
I/O ports such as LPT1, (printer ports are LPT1, LPT2, LPT3... ).

In this case, it is easier to open the computer and remove the secondary LPT
printer port card.  Then move the jumper on the card from I/O 378 to a non
conflicting address.  I recommend removing the card, starting Windows and
in Device Manager determining which I/O addresses are available the correspond
with addresses on the LPT printer port card.  Then setting the jumper on the
card to an empty I/O address and LPT2.  Turn off the computer and install
the card.  When Windows95/98/NT restarts it will find the card and set it up
with the new configuration that does not conflict.

I hope this helps.
