About this document</H1 ><P >When I first started the switch from APM to ACPI I didn't realize the kernel needed to be patched. My problem (insanely loud fan) was fixed just by upgrading to 2.4.20 (Debian packaged kernel with an earlier patch from <A HREF="http://acpi.sourceforge.net" TARGET="_top" >acpi.sourceforge.net</A >). Unfortunately after the first upgrade I wasn't able to <B CLASS="command" >halt</B > my computer without using the power switch to power-down my computer. It wasn't until later that I realized I had an old, ineffectual ACPI patch. This HOWTO was written to summarize the install process for myself, and hopefully help others who are also having a hard time finding information about ACPI. Please note: the main article outlines <A HREF="http://www.debian.org" TARGET="_top" >The Debian Way</A > of doing things. There is also generic information in the <A HREF="nodebkernel.html" >Appendix B</A > for those of you who prefer ... the generic way.</P ></DIV ><DIV CLASS="NAVFOOTER" ><HR ALIGN="LEFT" WIDTH="100%"><TABLE SUMMARY="Footer navigation table" WIDTH="100%" BORDER="0" CELLPADDING="0" CELLSPACING="0" ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" ><A HREF="index.html" ACCESSKEY="P" >Prev</A ></TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="index.html" ACCESSKEY="H" >Home</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" ><A HREF="copyright.html" ACCESSKEY="N" >Next</A ></TD ></TR ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" >ACPI: Advanced Configuration and Power Interface</TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" > </TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" >Copyright and License</TD ></TR ></TABLE ></DIV ></BODY ></HTML >
