ah, well... I guess I need to make this alittle clearer.

you can't extract a ATI driver, without "Almost" installing it.

so take the driver you want to mod, and click on install.
what happens next is it will extract all the files to the ATI file in your program files.
then when it says what card you have and you want to install and all that, just click cancel. then all the needed stuff is extracted.
then you just do the guide from the start.

getting the files extracted is what I should have said.

so say you want to install catalyst 6.2 using a X1950XTX.
then you let the ATI driver extract all the files to the ATI Driver folder, but cancel the install when it asks you what you want to do next.
it will say are you sure and all that, just say yes.
from there, do the guide like normal.

you dont have the install a driver, but you do have to get the file extracted to be able to do this.

as for the X1950...

Only Catalyst 6.8 Beta, 6.9 Beta, and I think 6.10 Beta have the X1950 in thier driver.
theres no Official ATI driver that supports the X1950 yet.
so use the Beta drivers.
