Write an INT 0x10 fake engine that forwards the requests over a serial line. It probably needs to keep track of the ``screen image'' in some buffer. This might turn out to become a mini-curses... ...and then, hope the best the setup utility is actually using the BIOS functions, as opposed to write directly to the screen buffer. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
