But instead of lamely asking "Does FreeBSD support MCA?" or "When will someone finish MCA support?" (which I suppose is still a valid question.) I will ask another question; "Anyone want to see what I've got so far?"

Granted, I'm still having problems getting the (until now ISA only) drivers working with these cards but if_ed_mca is able to send packets and complain about device timeouts and the if_ie_mca driver does manage to blow up somewhere inside of ieinit(). :) Basically, I believe that I've got all the pieces needed for FreeBSD to support MCA devices, should any device drivers actually be written. I've got a pile of stuff I'm trying to work through here so drivers should show up at some point (I think the 'aha' driver for the aha1640 will work out of the box but I don't have one to test that theory on. Yet.) I'm planning on committing this stuff to -CURRENT in a week or two, or when I actually manage to get a driver working, whichever comes first. I'd really like a few other people to try booting a kernel with this code on any of the MCA systems they happen to have laying around just to make sure that my changes do indeed work on other hardware than my Model 77. If someone has a ABIOS block device driver code hiding on their hard disk I'd really like to look at it (I already know about the Mach3 stuff). Thanks! -- | Matthew N.
