I sent a note to Averatec about this, and they asked me to post it on the
Linux forums, which I'm doing happily so that Google users can find it.

I wound up with an Averatec 6250 laptop machine for various reasons. They're
quite nice, built-in DVD player without the computer turning on and wastingg
battery, decent size screen, reasonably speedy Athlon CPU's, nice for
traveling and games. Unfortunately, I had to scrub it when I took it from my
old job. So for speed of installation, I tried to put Fedora Core 3 on it.

The screen does..... fairly odd things that interfere with doing the
anaconda based Fedora installation steps, even in text mode. The easy work
around is to hang an external monitor on the VGA output, enable that with
Fn-F8, and use the external monitor to do the installation with, which is
now smooth as silk. Turn off the external monitor with Fn-F8 when you're
installed, and you have a nice working little box.
