Windows 7: help me fix my 3850

WARNING: ANYONE RUNNING NVIDIA NFORCE3 OR BELOW FOR SOUTHBRIDGE CHIPSET CAN NOT USE HD CARDS BY ATI IN THEIR MACHINE ON WINDOWS 7 OR WINDOWS VISTA. IT IS IMPOSSIBLE. This is true?
i have Asrock AM2NF3-VSTA and Sapphire 3850 AGP
this config will not work??

Sorry, it is not within my control. There is absolutely nothing I'm empowered to do to help with your situation. NVidia has dropped support. This is why.

Here is a link to your motherboard. You can see that, in fact, it does use nForce 3.

There seems to be a possible workaround, but it is not a very practical. I refer you to this to do with it as you may.

This advice helped : BSOD on boot with 2x2GB sticks of RAM, but fine with 1x2GB stick?? - Windows 7 Forums
THX :-) :*

After many attempts, I was finally able to get my ATI Radeon HD 2600 AGP working in Windows 7 32-bit using the method described by Jack006 here: x1950 agp, nforce3, x2 athlon 4000 -problem

I have an MSI K8N Neo2 Platinum (nforce 3) with an AMD Athlon X2 4800+ (dual core). I also ran "bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS" to disable driver signing. I used the latest Catalyst 10.6 driver hotfix. I was not working until I ran the Nvidia 5.11 GART driver.

Now I have a CCC icon in the Windows 7 system tray and I have dual monitor working.
