It is widely known that the bridgeboard doesn't work with a V20, at least
in a plug-n-play mode.  Many PC's will, so perhaps your friend was over-
generalizing or guessing.  V20's have different clock requirements, so that
typically you need a faster V20 than the nominal 8088 speed,also the bridgeboard
may be sufficiently 8088 dependent to frustrate all efforts - dual port ram
designs can be fun...
