HALT Command Detect (Why disabled by default ?)

I own an MSI K7T266 PRO, Windows 2000 Professional SP2 and a TBird C series 1GHz.
I downloaded a program named WPCREDIT and documentation regarding PCI Configuration
Registers for the KT266/KT266A chipset from http://www.viahardware.com/download/viatweak.shtm

Specifically I point to the information about the register 95. Setting it from the default
of 1C to 1E my cpu temperature at idle went down from 49C to 33C. Incredible output !!!

The documentation of the plugin to use with wpcredit and KT266/KT266a unveils that the STPGNT
Detect is located at Register 92 and enabled by default in the MSI 6380. What is not enabled
is HALT Command Detect, located at the Register 95. Setting the Register 95 to 1E enables
HALT Command Detect.

16C down is very attractive and many users I have contacted are obtaining the same results.
Using other mobos (not MSI) they have to enable STPGNT Detect besides HALT Detect, the MSI has
it allready enabled.

So my questions are:
Is there any official information regarding this ?
Is there any reason why is 1E not set by default at Register 95 ?
Are there any side-effects of setting Register 95 to 1E (ie hardware damages, data corrruption) ?
Any idea will be very appreciated.
