Anyway, I grabbed an old disk, put 2.2.7 kernel src on it, and then tried to play with this one. > > If the register set does turn out to be approximately that of the 14F, > then I'd like to coordinate driver things with you. > Sure. Yesterday (yesternight?) I checked the code between NetBSD, FreeBSD and Linux for similarities for the 24F (quite interesting, there are (slight?) differences in initialization, board reset etc), and tried to see what the ultra124.sys driver of NT 3.5 does (3.5, because there is also a ultra124.dbg !). The differences seem to be a bit larger than I thought, but I haven't checked the whole 'SCSI CDB to adapter command block' stuff. But the regs are way off the 24F locations. Still, if I'm right, I hope I'll get at least a few sparks from the board... I'd like to use a similar source organization as NetBSD: they split the files in a common part and 14/34 and 24 specific 'stubs'. This is, anyway, cleaner than the current situation. In addition, looking at the differences in the Linux drivers for Ultra 14/34 might be interesting, too. And there is also the possibility that NT's Miniport model is similar to CAM, but I first have to delve into that a little. Let's see... But... > I've been swamped with other things and haven't had the time to spend > on them. Sounds terribly familiar...
