So what you are essentially saying is any OS that you install on any machine, that you have to add drivers to, is not running that OS??
Not in the sense that you can say the OS 'works' on the hardware in question. You might say you can make it work if you add/replace parts.
Ok, I will say this is totally subjective. I will conclude by saying that my Macbook pro is running CentOS 5.4 just fine, with no hardware removal or replacement :) I have an older Toshiba satellite used just for a file server, and it has 5.3 on it. To me, and employees, they work just fine. Almost any OS, M$ Windows included, has needed drivers at some point. Cheers, Chris
