Hi,   I have installed Debian 3.0 r3 on PReP and got 2 questions:   First when the system boots it asks the prompt: Linux/PPC: I always need to type root = /dev/sda3, otherwise system will not boot. Which file do I need to edit, so that I do not need to type these words every time the system boots at the prompt? And the second question is how to reconfigure the XServer, because during installation I guess I have configured something wrong because it does not start now, so what command  I need to use to reconfigure it?   Thank you, Vladimir
