I implemented a little hack a while ago that let you download a payload via xmodem over serial: http://www.coreboot.org/pipermail/coreboot/2006-October/016120.html It looks like most of the code has since vanished, but the xmodemReceive() function is still there, and might be useful for some kind of last-ditch failover mechanism. --Ed -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
