Preupgrade/Anaconda problem - 3rd time a charm?

[Steve Blackwell]

I've posted this question twice before but have not received any
replies.

I want to use preupgrade to go from F8 to F9.
I ran preupgrade, selected F9 and downloaded the data. When I rebooted
to complete the process, Anaconda started, correctly detected my
graphics card and started X. Unfortunately, Anaconda used the wrong
setting for my monitor which results in a blank screen with a" "Out of
Range" message. I can <Ctrl><Alt><F1,2,3,4> to see the various messages
and logs but I can see nothing on <Ctrl><Alt><F7>.

Q1. Where does Anaconda get the settings for the video card from?

Q2. Can I tell Anaconda to use the existing xorg.conf file?

Q3. Can I tell Anaconda to run in text mode?

Any other suggestions? My only other option appears to be to download
an F9 respin and burn a DVD.

Thanks,
Steve
