don't worry about these warning messages.. you just need to recompile
with out cdrom support..

making a new link to the src dir will not help boot problems...
what you need to do is boot off a floppy... then you can go through the
make config again and don't use any cdrom support. you should probably
replace the kernel image (probably called /vmlinuz or /zImage or /zmlinux)
with an older one that works (if you have an older one).

if you do not have a boot floppy made after you compiled a new kernel(you
should make one at least when you upgrade to the 1.3.[78]*) boot off the
floppy you made to install. mount the root partition (unless /usr has its
own parttion, inwhich case you should mount it too), as in /dev/hda1,
then if you have an old image some where replace the new one with it.
then reboot and once back in, go do make config and don't include cdrom
support. :)

hopes this helps
