root= for Fedora 17 pxeboot?

Sun Feb 26 18:00:37 UTC 2012

I have been using the following for the "default" file in tftpd.
It has worked until Fedora 17, which needs a root= phrase.
However I can find no information on what that phrase should be.
What should it be changed to?

prompt 1
default linux
timeout 100

label linux
kernel vmlinuz
append initrd=initrd.img ramdisk_size=9216 askmethod noselinux
