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 [http://acpi.sourceforge.net] acpi.sourceforge.net). Unfortunately after the first upgrade I wasn't able to halt 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 [http: //www.debian.org] The Debian Way of doing things. There is also generic information in the Appendix B for those of you who prefer ... the generic way.
