Quarterdeck QRAM only did that with NEAT or LEAP chip sets from Chips &
Technologies, by using the shadow RAM mapping, and required 1MB on the
motherboard, not 640K. I didn't think that was a significant enough
market share to mention.
It would also work with a LIM 4.0 EMS board as I mentioned earlier.

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.
