I don't have experience with T400, but on older models still it was very much the case that the BIOS image had some information in it, which was compared with the actual hardware at runtime, and in case of mismatch the platform did not boot.
I always assumed that it's a handshake between BIOS and the AT24RF EEPROM which includes some extra special functionality. On platforms with ME it wouldn't surprise me too much if all that moved into the ME, or even disappeared completely, but I *have* had the problem in the past. I didn't research exactly what information it is, or exactly what the handshake is, I always worked around the problem by flashing the backup. //Peter -- coreboot mailing list: coreboot@coreboot.org https://www.coreboot.org/mailman/listinfo/coreboot
