I know literally dozens of people (including myself) who would try this. It is, however, extremely unlikely that it'll actually be *required* anywhere. Is there a specific reason it doesn't work (i.e. architectural features that no longer exist on AMD64, like lack of third-party DMA on LPC bus, though I know that's not a CGA/EGA/MDA thing), or is it just a highly unlikely scenario? - Dave
