To prevent the duplicate messages from SeaBIOS, one can set the SeaBIOS debug level to 1 and set the "etc/screen-and-debug" setting as described at: http://www.coreboot.org/SeaBIOS#Adding_sgabios_support This wont prevent duplicates from grub, but if sgabios works properly then you may be able to disable grub serial. > However, in one of my latest e-mails I suggested that SeaBIOS should not > control serial input in memtest since memtest has its own code for serial > input handling.

I'm not familiar with memtest internals, so I can't help here. -Kevin -- coreboot mailing list: coreboot@coreboot.org http://www.coreboot.org/mailman/listinfo/coreboot
