Why Ur Laptop may Not Work with Vista

A very common component in laptops is Intel integrated graphics. In his blog, Blake Handler reports that the widely used Intel 915 Graphics chipset is physically unable to run
Vista’s Aero/Glass interface:

Intel’s Chuck DeSylva, explains “The WDDM Vista driver spec came out long after the 915 design was complete and in production, and even though it has advanced features like Pixel Shader 2.0, there is a missing hardware feature, called the Hardware Scheduler, that 915 lacks, and without that, it doesn’t meet the WDDM spec from Microsoft, and we (Intel) can’t release a WDDM driver for it.”

Now I know why my Thinkpad can’t run
Vista.
