I have finally managed to make the ethernet card work. I installed the Marvell drivers and now it works fine. Thanks for the help.
I have installed the SMP kernel from within synaptic by the way.
The only problem that i face now is that the 3d accelleration of my ati radeon x600 pci-express graphic card doesn't work. Below is the graphics section of the xorg.conf file :
Identifier "ATI Technologies, Inc. RV370 5B62 [Radeon X600 (PCIE)]"
Identifier "ATI Graphics Adapter 0"
Option "VideoOverlay" "on"
Option "OpenGLOverlay" "off"
KDE works fine but I cant play any 3d games such as quake4.
I would appreciate any help on this as I havent found anything helpful so far over the forums.
Thanks in advance
