Look I apologise for my tone, I simply do not understand what the release 
notes are getting at. I am sure when I get it right it will seem stupid to me 
too.

I have a good command line background, but I have never needed to create my 
kernel tree. I have never even needed to recompile a kernel either, so 
understanding where to put things related to the kernel is obviously 
something I need to learn.
The only thing I use it for is modem drivers, which always ask for the 
sources.

I get up to step three with no errors, in step three it tells me which 
directory I should be in. however step four does not say if I must change 
directories or not, 
Since I am using the the stock 2.6.9-1.667 i686 kernel src, there must be a 
proceedure for doing this step by step, I can't see how a standard install on 
my PC will differ from anyone else's PC with a standard install. 
So even if you have a i586 kernel and I have an i686 kernel I am (believe it 
or not) smart enough to know that I am to replace your i586 with my i686.

So all I need to learn how to do, is install the kernel source tree as it was 
in the past with FC1 and 2 , the sources where in /usr/src/linux	and where 
installed from the kernel-sources rpm, which is no longer available.

So in a nut shell 
step 1
download the kernel src rpm  (done no errors)
step2 
install the kernel-<version>.src.rpm (done no errors)
step 3 
cd /usr/src/redhat/SPECS/ and run 
rpmbuild -bp --target=<arch> kernel.spec (done no errors)

[root at check39 SPECS]# uname -a

[root at check39 chadley]# rpm -Uvh kernel-2.6.9-1.667.src.rpm

[root at check39 SPECS]#

step4 
[root at check39 SPECS]# cd ../BUILD/kernel-2.6.9/linux-2.6.9/configs/
[root at check39 configs]# ls
kernel-2.6.9-i586.config  kernel-2.6.9-i586-smp.config  
kernel-2.6.9-i686.config  kernel-2.6.9-i686-smp.config
[root at check39 configs]#

The config I need is the kernel-2.6.9-i686.config which I must copy to 
somewhere as .config 
The question now is where.
I do not have a /usr/src/linux directory must I create one or is this 
different? Does it exist somewhere else or is it called something else!
locate does not find it either, I have run updatedb too.


what do I do now?

Thanks
