PC BIOS's probably still all have code to deal with BIOS-less mono video cards; why not just decode the video memory range and update internal state with the memory writes, then convert them into VT100 codes (or, rather, the card should have a downloadable termcap in NVRAM so that I can plug in my tvi925!...) Don't forget that during the "pre-boot" phase you need to pretend to be a keyboard, too, not a serial port, or else you can't run setup. Bill
