Building new kernel does boot, kernel panic, need help,thx

[Laurent Klefstad]

I'm trying to make a new kernel on my linux station, but each time i
boot whit it
i've got the following message:
"kernel panic unable to mount root fs"

Can someone tell me what I missed in the configuration kernel ???
I'm making:
make config
make dep; make modules;make modules_intall;make zlilo

my lilo.conf look likes:

boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
linear
default=linux
 
image=/boot/vmlinuz-2.2.14-5.0  <-- original Redhat 6.2 kernel, works
fine
        label=linux-old
        read-only
        root=/dev/hda2
 
image=/vmlinuz
        label=linux         <-- my new kernel
        read-only
       
root=/dev/hda2                                                                                  

Thx.
