This is not easy to do on most 286 machines. If you have 256K chips (most
likely) then you MUST have 18 of them installed to maintain a 16bit data
path, this implies a minimum of 512K. An 80386 is even worse, you must have
memory in 32 bit increments meaning that 1Mbyte is the minimum for 256k chips.
Now if your machine uses 64K chips (I don't think one exists, not a 286 or 386
anyway) then this wouldn't be a problem.
