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.)

I belive OS/2 1x did this. IBM insisted on
OS/2 supporting the 286 while
Microsoft wanted to skip it and support the 386 and above (this was one
disagreement between IBM and Microsoft that lead to the split between the
two).
