FC7 live pen drive?

[William Murray <W J Murray rl ac uk>]

  Hello guys,
            I am trying to make the FC7-T2 into a live pen drive.
Three partitions, 0=normal pan 1=fc7-t2 2=boot
The boot area has grub on it, and I booted knoppix fine.  For FC7t2
I have tried:

title=FC7t2 live
        root (hd0,1)
        kernel /isolinux/vmlinuz ro quiet
root=CDLABEL=Fedora-7-Test2-20070226.1-LiveCD rootfstype=iso9660 livecd
        initrd /isolinux/initrd.img

which starts to boot, i.e. it reads the isolinux area, but does cannot
find the root file system. Can anyone suggest how this might be fixed?
 Thank you,
 Bill
