Thanks again Clay :)

But, Ive done what you suggested to (that's what I said above).  I retried with _exactly_ the method you described right above, same bad result: black screen, white pointer, totally locked up (this is when boot from live KU 910 cd).

It's curious how we have the exact same laptop, & different behaior.  Not to say you've forgotten [ ;) ], but have you done that _exact_ procedure (which you just described) with a KU 910 live cd, on that laptop, recently?  Perhaps something is working differently now.

Any further suggestions you have will be appreciated. :)
