How so? Which Unix are we talking about?

You would obviously want to copy it to RAM to avoid the slow CD access times, esp. for compiling stuff.

I think it was too fast for some pre-existing common apps, incompatible (push sp, pop sp), especially regarding the "pmode-only" approach (e.g. some stuff wouldn't run). You couldn't even run multiple DOS apps at the same time, which made Bill Gates (supposedly) call it "braindead". So it was a big switch. OS/2 1.1 was probably the last to fully support 286s. And WfW 3.11 was 386 only. For whatever reason, the 386 became much much more popular, even to the point of heavily eclipsing the 286 in software development (even for apps that didn't need that much RAM). You don't see a lot of 286 pmode assembly apps these days. (No free 286 DOS extenders that I know of.) With the exception of some Borland tools, I'm not sure it was ever that well supported (from my limited view in hindsight).

As far as PAE, it hasn't really taken off yet (except for server OSes??). We don't all have that much RAM (comparatively) yet. Maybe that's the way to go for keeping V86 + 16-bit stuff working even with high amounts of RAM. So who really needs x86-64? ;-)
