I ran a 2842 along with my 1542 for a few days while getting the 2842
to work under NetBSD.  I suspect there will be a little difficulty
finding where the bios for each card will go (unless PCI takes care of
that -- I know next to nothing about PCI) but they will work with each
other.

However, the 294x series uses the ahc driver, not the 154x's aha
driver.  You will need to add that to your kernel.

Also, the ``ultra'' I don't think is supported as an ultra card (the
2940uw is ``ultra'' I think) and I don't know if it will work as a
plain old card.  FreeBSD's aic7xxx.c and sequencer code is different
than ours is -- I was going to compare them and experiment, but then
classes started.  :)
