There are Well, if motorola was so stupid that you can kill it by mistake...

AMD's PowerNow at least will not let you overclock and/or overvoltage. You are free to undervoltage, but that's crash-only. Its true that HP Omnibook xe3 probably can be damaged, provided that its CPU fan fails and there's just enough airflow to keep thermal protection from kicking in. Its harddrive overheats in such case. I guess that's uncommon enough. Pavel -- Horseback riding is like software... ...vgf orggre jura vgf serr.
