I have recently installed SCO Xenix 2.2.1 on a 286 box which has an 
Everex I/O card (which used to be in a PC XT).  I have tried several
times to activate the lp system and cannot get anything to print out 
properly.  The problem occurs as follos:

I set up all the required stuff, activate the scheduler and enable the
printer.

I submit a print request and the printer begins to print the banner page.

After about 10 lines the system says:
interrupt from unknown device  vec=2
panic: unknown interrupt

** safe to power off **   (etc)

At first I thought this problem was related to the lp syste, but I also
get it when I "cat <file> > /dev/lp1".

There are no other parallel ports in the box.  All the documentation
I find on interrupt vector 2 states that this is a general hardware fault.

The parallel port works fine under DOS

Any Ideas ?  (email is fine)

thanks,

PS, I have installed this release of SCO Xenix on many 386 systems and had
no problems.
