I am trying to build a image to boot into ram via tftp to another machine, but when I go to boot the machine I get

Warning: unable to open a inital console
Kernel Panic: no init found try passing init=option to the kernel

I built the kernel to support a ram disk, and i am useing FC3

label 0
kernel vmlinuz-2.6.12
append initrd=rootfs.gz ramdisk=65537 root=/dev/ram

The ramdisk needs to hold a minimal root file system
Any help would be appeciated.
