I didn't see the source, only the 50 meg distribution file. I'll check out
the path you posted.

I'm not sure if the IIvx is an exception to the rule, or what, but the video
sits in Slot 0. I've been looking at other drivers and they seem to do a lot
more hits on the NuBus-type space. It seems like there's three different
types of video:

1. Card based video
2. Slot "E" type video
3. Proprietary Slot "0" video.

I know the IIvx falls in 3. Doesn't the IIsi fall into that category too?
What I need to do is run a survey and get some information.

I'll have to take a look. These are prob. the types of physical addresses
I'm looking for.
