While I haven't bothered to install 8.1 on any of my machines here, I have to say that Mandrake 7.2 and Mandrake 8.0 are great at detecting hardware.

On both my Compaq M700 lappy and my home-brewed Athlon system I have only seen Mandrake get the video card wrong during the install on the laptop. Fortunately, I knew what the correct card was and corrected it before it became an issue.

As our "old friend" Brett G. would say, YMMV.
