Instead of using 'make zImage' when you're at that last step, try using
'make bzImage'. Bzipped files are MUCH smaller than their zipped
counterparts. That's what the error message means when it says use
bzImage, btw. And also, just in case you don't know what to do to get your
kernel working after it has been compiled and such, there are still some
more steps left over. What you'll want to do is issue the command:
# cp /usr/src/linux/arch/i386/boot/bzImage /boot/bzImage
and then use your fav. editor (vi, emacs, joe, whatever you like) to edit
the file /etc/lilo.conf so that it points to your new kernel instead of
the one it points to now. That should get you going; any more questions
and let me know, I'll be glad to answer them (if I can....) Good luck!
