Hi,
I am using qemu to emulate win2k on FreeBSB-6.1. I particularly wanted to run
some proprietary software requiring a dongle on the parallel port and made
the patch attached. It seems to work for me so I thought it might be useful
to others. (I haven't attempted to print anything but win2k installed an
attached printer.)
Cheers,
Rob Jenssen
