No it doesn't; the only bit that _needs_ BIOS to work is BIOS HD/FH driver (d'oh) - if flash is mapped to 186's memory there's no need for such a driver, slightly modified ramdisk driver will do the trick. Other bits (serial, parallel, direct console) don't need BIOS to work, they just get port addresses from it (but these can be hardcoded anyway) .. and console driver will be replaced with serial console in embedded application.
