My balls weren't big enough to try it :-) Maybe today, with all of the
documentation, it might be fun to explore. But with emulators all the
rage with the kids these days, exploiting LOADALL means that your
program would only run on the real thing.

To be honest, they were right. If you wanted
more than 640K on a 286,
it was easier and faster to work with a hardware LIM EMS board than it
was to try to do it yourself via protected mode. (I'm talking about the
period before HIMEM.SYS and the formalized XMS standard, but even then,
XMS copies RAM in and out of the 640K-space, whereas EMS would just
slide the window around which was a hell of a lot faster.)
Yes and no--if you were savvy enough to know how to use LOADALL, things got
somewhat simpler.
