I found 2MB worth of 256x4 DRAM for my 2091 and it made a huge difference in
loading times compared to the same board and drive with no ram at all. Best
place to find it is on old ISA/VLB video cards where it can be found
socketed for easy removal (and can always be put back in the video card if
needed).
