... I have driver version 188.8.131.5247 on a ATI Mobility Radeon 7500. ... Are there any Windows Vista or Windows 7 drivers for this display adapter, or is there a fix for this?
There are many of us running Win7 successfully on T40-T42 models with ATI 7500 GPUs. I have run with no graphics problems with the driver listed below for 1.5 years with Win7.
You will want to find driver version :
ATI MOBILITY RADEON 7500 (Microsoft Corporation - XDDM)
This driver is hard to find. There are references to this driver in other threads in these forums, but all of the links seem to be dead now. You may be able to find the driver at some of the driver sites where you must sign-up in order to get to the driver downloads. There have also been discussions that the Radeon 9000 driver (still 184.108.40.20606) will also work ... but that might require modifications that I am not knowledgeable of in order to get it installed on a 7500.
The folder that I have kept is approximately 5.85mb. It does not contain an installer and the driver is 'forcibly' installed manually.
