Additionally we need to hook the sercon code only into a few subcalls, and with the exception of 00h (aka set-mode) none of them are useful for software which wants program vesa modes. So, yes, I think that could work. I'll go have a look, starting with old linux xorg+x86emu. Do you remember which windows versions have problems too? cheers, Gerd _______________________________________________ SeaBIOS mailing list [email protected] https://www.coreboot.org/mailman/listinfo/seabios
