On a 286, you could use various LIM 4.0 compliant

Quarterdeck also had a program that would expand available
memory on a 286 above 640K called QRAM. I used to have it
many moons ago, but got rid of it when I was cleaning
house. Somehow, it also would map memory into the A000-AFFF
on a mono card, but would also make more memory available
even with the EGA card. Can't remember how though.
