But not many machines have physical memory in the hundreds of megabytes ranges.. so regrettably, I doubt that this would work in practice. Use virtual memory you say? Well.. in that case a 386sx will do the exact same internal translation as a 386dx, producing no observable differences either. Better luck next time. -- ___Mark S.
