Before I reply to the mail below (on useable irq's) let me make an
important point. I am positive that it is IMPOSSIBLE to get an
irq/port scheme that will work on ALL laptops. The engineering
choices are then not to produce a workable pcmcia system or to
produce a system that works on MOST laptops. I would choose the
latter and I think that it is not too hard to come up with irq/port
choices that will allow most laptops install netbsd 1.3.

We might add 3 [No reason that the install floppy needs to support 2

And not passed by some ibm laptops.

I think that the pcic could be 10 not the pcmcia -- this would work ok.

I'm sure that some laptop will have trouble with 11.
