F7 install CDROM unrecognized

[Gerry Reno]

I've been trying to install Fedora 7 today from DVD on a couple 
workstations and also in a QEMU Guest on an FC6 machine.  The install 
gets stuck everytime when I OK the CDROM installation type screen.  It's 
not recognizing the CDROM drives for some reason and just keeps 
prompting for driver selection for this install type.  Is there some 
parameter that I need to pass in?  I've been working on this for hours 
and no luck on either machine or with QEMU.
