Worked on it last night, and got this card to work. Showed it off this morning.
The download I used was:
It's the driver only; 2.68gig; extracts to 6.0gig; there is no setup.exe; there is an inf.
Go into Device Manager - Update Driver - and direct D/M to the pci_ven subfolder.
After it installs, reboot - and voila! In parentheses next to RADEON 9250 is (Microsoft Corporation-XDDM); driver version is 220.127.116.1106; driver date is 8/15/2006.
Full screen, stable, no BSOD's on shutdown. Stuttery on YouTube which suits the boss just fine. Runs all his apps. Able to surf the net okay (again, no videos). In his office environment, it's good enough.
On my Google search, I came across some Vistaheads that found this (or modded it) and got it to run successfully. Type it in to the search bar; I believe it was the first listing that had it - **************. The 4shared site claimed that M/S made them remove it.
