   There is only few mobos which *really* do shutdown looking
to Athlon chip diode (in particular, one mobo from Fujitsu-Siemens).
And I know only about 1-CPU mobos :-(
Tyan don't say nothing simple because their mobos don't do this :-(
Beginning from July 2002 AMD certifies only mobos having
this feature, but Tyan mobos, as I understand, were developed
before this date.
