I agree it is something related to the BIOS. My understanding
is that there are these small routines built into each adapter
in some interpreted language that the PCI BIOS runs for each card 
to set it up and that code is what I always figured had the problem.

The OS could probably move things around by writing to
the adapter's registers though.

If you have an Adaptec card, put it last and see what happens.
I always get conflicts with my network card. The 3940W in
particular is nasty because it uses two interrupts...

Any HW people out there who know how it really works?
