Sorry COLGeek, but AMD provides drivers for mobility HD2000/3000/4000etc. but only for Windows Vista and Windows 7, but not for Windows XP (try to search a driver for Mobility HD 4000 i.e. for Win7 and then for WinXP on the AMD website!)... why damned AMD?!? While Nvidia provides drivers for every operating system!!
And the Mobility Modder v22.214.171.124 Final Version (latest version updated to May 2009) is unable to mod 10.x series Catalyst Drivers...!
I tryed also with the latest Catalyst 10.7... not working!! >=(
I can't believe that... why AMD has intentionally forgot to support an operating system that's still used by the 70% of the PCs?!?
Nvidia has a more serious behavior from this point of view... =(
Nvidia doesn't suffer the same problem... they recently (from about 5-6 months) have added the support for mobile GPUs, in fact is possible to download from their website the drivers for GeForce Go 7000 Series and further (8000, 9000, 100, 200 etc. series - Nvidia Verde Notebook Release) also for Windows XP, so you don't have the problem with your Dell.
My GPU is an ATI Mobility HD 3650, I have tryed different ways to update drivers via Mobility Modder .NET but the latest drivers I was able to mod were the Catalyst 9.3 (more than 1 year ago!)... has anyone tryed with the latest Catalyst drivers releases? Please help me...!
