I tried this a couple of ways.  If I add just the kernel file, and not 
the parameters, like so:


It starts booting, but then dies with:

Kernel panic - not syncing: Attempted to kill init!

If I add the "ro root=/dev/VolGroup00/LogVol00" to the kernel line, I 
either get a kernel not found message (if the parameteres are inside the 
quotation marks), or an invalid parameter message (if outside the 
quotes).  I tried adding:


(with and without a "ro" at the end), and it still boots the kernel but 
then panics.  Which is what I'm starting to do! :)

Thanks again.  Full console output from a boot below, in case it helps.
