Patje's method is probably a lot easier.
The hardway:
First Post, anyway I had problems installing Ati's lame drivers "Try switching to Standard VGA" bla bla bla.
I used Omega drivers just for the small comfort of reading "Mobility" in the title.
To install go to
display apapter properties->update Driver->Ill pick source->have disk->find the *.inf file ati unpacked into the C:\ati\whatever folder by default and open and you'll get a list of all the vid cards.
Pick yours (I don't think stock drivers have Mobility in the title, pick radeon 9600 or whatever I guess).
Sorry if this is old news, but I assume everyone has this problem and thought it was worth mentioning. Please e-mail me
tikill@hotmail.com if you want better instructions.
