FC6 install failure; insert disk - 99 error

[Jude DaShiell <jdashiel@xxxxxxxxxxxxxx>]

I used a text install and did media checks on all disks first.  All disks 
passed media checks with ok to use.  So I try to run the rest of the 
installation and fail.  After package selection I left at defaults the 
system gets ready to install the first package and this message comes up 
claiming the install media is corrupt and telling me to insert disk - 99. 
I have no clue what to try after that other than a kickstart file or a 
telnet install.  Might there be another way to salvage the situation for 
an install using text?  I tried this on an old Dell and a new AMD Athelon 
K7 machine with identical results.  Can anyone explain what I ran into and 
is it likely to still be a feature of FC7?  I'm not the only one with this 
problem either, though I use a speakup modified Fedora, I read about 
another blogger over in India who didn't use a speakup modified Fedora and 
ran into the same problem.
