I tried using INT 2 on my Archive controller, too, and never could get it
to work, so I took out a parallel port card, and used INT 5.  Then, later,
I had trouble with a WD 8003 ethernet board, and needed to run it on INT 2,
but luckily the documentation with SCO TCP/IP specifically mentioned that
if you set the hardware for INT 2, that you had to tell the software INT 25.
I wish the Archive installation docs had mentioned this, my headache back
then would have been much less severe.
