Welp, Thats not sure fire proof.. But I do *sorta* agree.
irq conflicts can be quite strange.. :)

Whoops.. Yup it was. I try not to re-read my messages before
sending, I get to blabbling when I do.. :( (Like now :)

Welp, That didn't help. How does one find the LPT's IRQ usage under 
FreeBSD?? Someone please.
(Geuss I should of looked at mine before asking. :( )

What are your cards physically set at as far as irq's??
I'll *assume* lpt0=7,lpt1=5, But what about lpt2??


-Enjoy
