I put "problem" and "solve" in quotes because I disagree that the problem that need to be solved is identified correctly. The correct problem to be solved IMO is writing Windows driver for the device. [VR] This one shouldn't be too complicated. Can be done on weekend. -- =09=09=09Gleb. _______________________________________________ SeaBIOS mailing list SeaBIOS@seabios.org http://www.seabios.org/mailman/listinfo/seabios
