1. About this document
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
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 The Debian Way
of doing things. There is also generic information in the
Appendix B for those of you who prefer ... the generic way.
