FC6t2 rescue CD not usable?

["Robert P. J. Day" <rpjday@xxxxxxxxxxxxxx>]

  just for fun, i tried to boot into rescue mode of a FC6t2 rescue CD
on my FC5 system.  after selecting language, keyboard and CD-ROM, i
got the error that a Fedora Core CD was not found in the drive.

  hints?  is this a known issue?  thanks.
