You need to know that, in all likelihood, the driver will not install, or even if it does, will not work on Windows 8.
I have an old Toshiba notebook that uses the Intel 915GM chipset and I've already tries all the tweaks to try to get that driver to work -- and it won't. Problem is that driver is an XPDM driver, written without WDDM support. Back in Win7, MS supported XPDM drivers, so it would both install and work. But, MS removed XPDM support from Win8, so it won't work anymore.
