I'm not sure on this one. If qemu tells seabios to load a rom, I think it really should do that. If future versions of qemu will be changed to not request sgabios when sercon is enabled, then maybe the issue isn't large enough to worry about (it only affects no-graphics, new seabios, old qemu). If that's not safe, perhaps we should revisit how seabios enables sercon so there is no confusion. -Kevin _______________________________________________ SeaBIOS mailing list SeaBIOS@seabios.org https://mail.coreboot.org/mailman/listinfo/seabios
