Select the appropriate directory- v2.0 if you are running a 2.0.x
kernel, or v2.2 if you are running a 2.2.x kernel.

If you are looking for earlier versions of the kernel (such as 1.2.X),
these are kept in <A

>Old Linux kernel source directory</A

>Choose the appropriate kernel - usually the most recent one
available is what you are looking for. Retrieve this and put the source
tar file in <TT

<EM
>Note</EM
>: a 'tar' file is an archive - possibly compressed (as are the
Linux kernel source tar files) containing many files in a number of
directories. It is the Linux equivalent of a DOS multi-directory zip file.&#13;</P

<TT

>Now, <TT
CLASS="LITERAL"
>cd /usr/src/linux</TT
> and read the README file. This contains
an excellent explanation of how to go about configuring and compiling a
new kernel. Read this file, (it's a good idea to print it out and have a
copy handy whilst you are compiling until you have done this enough
times to know your way around).</P
