Managed to compile my kernel.  I have now run into another problem.  When 
I run 'lilo' it complains with

/vmlinuz  too big.

WHy is this happening, do I have to 'scale down' my options to get a 
smaller kernel??

thanks in advance
Glenn

I do a "make zImage" and it creates a compressed kernel in the 
boot/i386.../zImage.  The directory is shows as one of the last
"leaving" lines when you do the make zImage...

You are using the wrong kernel image. The image that you want is  
src/linux/arch/i386/boot/zImage. Move this zImage to your /vmlinuz
(rename the old one first just in case). when you have done this 
run lilo. This zImage is the compressed kernel image that lilo uses
to boot. This is in the README in the src/linux directory.

hope this helps.

Are you attempting to install the image contained in /usr/src/linux or the
one in /usr/src/linux/arch/i386/boot.

The second path contains the real compressed boot image.

I usually compile the kernel with `make zlilo`.  This installs the correct
image for you.

o
Sounds like you are using the kernel in the bottom of the source tree.
This is uncompressed.  the zImage kernel is in arch/i386/boot I believe.

But look for it in the /arch/i386 directory tree.

Now try a "make boot". I just finished 1.2.1 and "make zImage"
actually made "vmlinuz" while "make boot" created zImage. You 
have to do both. I'm using loadlin/zImage.

I haven't seen the original posting, but you can get the message
complaining about the size of the newly installed kernel from Lilo.
This happened to me when I forgot to reconfigure Lilo after kernel
compilation (or after you install a different kernel from some
distribution).
