<P>athcool is a small utility, enabling/disabling Powersaving mode for =
AMD=20
Athlon/Duron processors. </P>
<P>Since enabling Powersaving mode, you can save power consumption, =
lower CPU=20
temperature when CPU is idle. </P>
<P>Powersaving works if your kernel support ACPI (APM not work), =
because=20
athcool only set/unset "Disconnect enable when STPGNT detected" bits =
in the=20
Northbridge of Chipset. To really save power, someone has to send the =
STPGNT=20
signal when idle. This is done by the ACPI subsystem when C2 state =
enterd.=20
</P>
<P><STRONG>WARNING</STRONG>: Depending on your motherboard and/or =
hardware=20
components, enabling powersaving mode may cause: </P>
<UL>

<LI>a slowdown in harddisk performance=20

<P>If you met those problems, you should not use athcool. Please use =

<STRONG>AT YOUR OWN RISK!</STRONG> </P>
<H3>Supported Chipsets</H3>
<P>I have tested VIA KT266A (EPoX EP-8KHA+) and nVIDIA nForce2 (EPoX=20
