Need RST Driver For ICH9R

I need a Vista32 RST driver ... version 9.6 or later ... for the 82801IR/ICH9R controller hub. The latest version listed in the download center is 11.2.0.1006 but because of the ambiguity in its readme file I'm not sure this is the right driver.

Of the chips listed, one is listed as "Desktop/Workstation/Server Express Chipset SATA AHCI Controller" ... is this the ICH9R?

Thanks!
