I used to have F9 on my HP pavillion dv8000. I have been trying to install F10 (and even CentOS 5.3) on it and, during the installation process, when I choose the keyboard layout (english) it doesn't go on. Weird because I am using the same disk I succesfully used to install F10 on my desktop. What could it be? The same problem happens when I make the installation process in text mode...
