A.1. Getting the Source Files
Download a fresh kernel from 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-<version>.tar.bz2.
 | 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 /pub/linux/kernel
directory on the 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
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.
