Additional info on the Vista SP1 compatibility issues

There has been a fair amount of discussion about issues with Vista SP1 having conflicts with some hardware configurations and various drivers. Some additional details have recently surfaced about the incompatibilities, and it is pretty damning of Intel. The gist of it is that the Intel 915 chipset is the problem. Microsoft initially didn't plan to support it on Vista and it was added in to the OS late in the development cycle because Intel had a ton of inventory and was still trying to sell the boards to make their numbers that quarter. So they bullied Microsoft into supporting the platform, and sold a ton of the boards to HP and Lenovo for use in their computers. And now those are the systems that don't take SP1 very well. Once Microsoft decided to support the hardware they probably should've planned on supporting it indefinitely, rather than just through the RTM stage, but this is still a pretty interesting look at the behind-the-scenes efforts in getting an OS out the door. Symantec is involved as well, with their Endpoint Protection driver, but the main issue seems to be Intel.

So much for the "Wintel" synergies, I guess.
