You have to tell coreboot where to route LPC post codes to. It defaults to "None", but you can choose PCI or LPC. I have never tried to print post codes with coreboot, though. I would try using the serial port though, as it is more practical for debugging than post codes. > Thanks for your help > Keith > _______________________________________________ > coreboot mailing list -- coreboot@coreboot.org > To unsubscribe send an email to coreboot-le...@coreboot.org Best regards, Angel Pons _______________________________________________ coreboot mailing list -- coreboot@coreboot.org To unsubscribe send an email to coreboot-le...@coreboot.org
