The real solution would be TXT from new intel chips. This can provide runtime secure boot so the chain of trust is _really_ short. In fact only the cpu, northbridge and the signed module provided by intel. I've tested it with an intel executive DQ45 motherboard and a q9550 cpu. It works though requires a good deal of work (patching included). http://sourceforge.net/projects/tboot/ michael -- It's already too late!
