The stomping problem is still there in that case. If there's any stack, it can be stomped on by the code executed from the option ROM. I can see two ways out, both not really nice: - checksum all important code and data, then compare the result - reload all code, checksum only the data - reload all code, preserve no data (which would include BIOS tables) Regards, Carl-Daniel -- http://www.hailfinger.org/ -- coreboot mailing list [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
