There have been success reports with SeaBIOS booting Windows 8, so it's not a general win8 problem. If possible, try to pull the disk image into a QEMU VM and see if it has the same crash when running QEMU with a native instance of SeaBIOS. Also, make sure the problem is still present with SeaBIOS debug level 1 - very high debug levels are known to cause issues with some software. -Kevin _______________________________________________ SeaBIOS mailing list SeaBIOS@seabios.org http://www.seabios.org/mailman/listinfo/seabios
