By the way, ATI doesn't make drivers for it's Mobility series of video
chipsets available on its web page. You are forced to download the drivers
from the vendor that made the laptop.

Ati does make the mobility chips, but many system makers, lke Sony, Toshiba
and IBM are known to modify it in some ways, so that standard ati drivers
doesn't work.

However, in most cases, you can get ATI catalyst to work on your mobility
card. Just download a little tool called "mobility modder" from
driverheaven.com and it will do the rest.

You can also try Omega Drivers, they work with most mobility chips available
on market.
