Kernel Compile error

[Jon <j_dabrowski@sprynet.com>]

I am newbe trying to compile kernel 2.3.99pre9 on a mandrake 6.0 box running
kernel 2.2.9 and I keep getting this error message:
[root@localhost linux]# make zimage
make: *** No rule to make target 'zimage'. Stop.

What am I doing wrong?
I did make config, make dep, and make clean. and I still get the error
message
Then I tried to recompile the 2.2.9 kernel and I got the same error message
when i tried make zimage

Thanks for the help
Jon
