The Kernel
Remember to choose "F" for full when you download your kernel source. http://www.kernel.orgDebian-ized kernel
maxx's pre-patched 2.4.20-8 kernel source package. For more information see maxx's notes. http://people.debian.org/~maxx/kernel-source-2.4.20/ACPI kernel patch
You'll need to pick the version that exactly matches the kernel you're using. http://sourceforge.net/project/showfiles.php?group-id=36832acpid

If you are using a 2.4.x series kernel, the kernel will need to be patched
before you can add ACPI support. Although ACPI is included in the 2.6.x
series kernels you should check to see if any patches have been released to
fix bugs. You can find this information on the ACPI4Linux site.
A.1. Getting the Source Files
Download a fresh kernel from [http://www.kernel.org] www.kernel.org. You need
to make sure you get a full kernel. Find the "latest stable version of the
Linux kernel" and click on F for FULL. Wait patiently. A bzipped kernel is
about 26M. If you're feeling particularly geeky you could also wget http://
kernel.org/pub/linux/kernel/v2.4/linux-.tar.bz2.
Tip You may or may not want the latest stable version. For more information
read the Section 7.1 section of this document. If you decide to use a version of the kernel that is not published on the front page, use the [http://www.kernel.org/pub/linux/kernel/] /pub/linux/kernel directory on the [http://www.kernel.org] kernel.org site to find the kernel you'd like.While you're waiting, grab a copy of the patch as well. For the 2.4.20 kernel
use the 2.4.20 patch. It's dated 2002.12.12. You'll need to know that number
later when we check to make sure the patch worked. If you are using a
different kernel version make sure you take note of the date of your patch.
Your numbers will differ slightly from the one I use later on.
Once you've got those two files (the kernel and the patch) unpack them and
patch the kernel.
A.1.1. Patch
Now we're going to actually patch the kernel. I take one extra step from
[http://acpi.sourceforge.net/download.html] the instructions at ACPI4Linux.
Instead of gunzipping and patching in the same line, I use two lines. This is
purely a matter of preference. When you patch the kernel you want to make
sure there are no error messages. (There is no "yay" line, instead look for
the absence of errors.)
* cd /usr/src/linux
* cp acpi-20021212-2.4.20.diff.gz /usr/src/linux/. (Your patch filename
will be different if you're not using the 2.4.20 kernel.)* gunzip acpi-20021212-2.4.20.diff.gz
* patch -p1 < acpi-20021212-2.4.20.diff (this is the actual patching
part)Once you've finished patching your kernel, continue reading at Section 10.
