I was just in the process of looking for an AM2 board with AGP a few weeks ago, I could have used a nice concise list like this 😀

I ended up getting a trio of ASRock's AM2NF3-VSTA boards, sold as defective on ebay and explicitly described as not working at all. I figured I'd be able to fix one of them with the spare parts from the other two; or maybe if I was really lucky, one of them wouldn't even be defective in the first place. But then all three turned out to work just fine, so no idea how the seller was testing them 😀. Anyway, can confirm this particular board works mostly fine with Windows 98SE and Windows ME, using nvidia's unified nforce drivers. I'm still experiencing some stability issues, mainly in the form of windows hanging during boot up or shutdown, but that may simply be down to me using 1 GB of memory for now (still waiting on some lower capacity DDR2 sticks to arrive).

I have the Biostar K8M800 Micro AM2 board. Bought it new back in the day from Newegg as a budget computer for my son. Still works great today running Linux Mint with a Athlon 64 x2 4200 cpu and Ati 1650 agp card.

I have one as well. with a PhenomII-X4 and 4GB of RAM, running Linux. It's quite a bit slower than I would expect for the specs (possibly limited Linux nF3 chipset support?), but otherwise rock-solid.

What happens with Windows 10 on an AGP system? If you have an older version does it warn you before installing 1607? Can you run userbenchmark?

Sorry to answer my own post, but I did find a decent answer.

I have the same issue on two AGP systems as of the August 2 Windows 10 update (version 1607 build 14393) coming from version 1511 (build 10586 fully up to date prior to the anniversary update). The issue with this update is that the CPU to AGP controller reverts to a PCI-to-PCI Bridge upon upgrading from build 10586 to 14393. This means that NVIDIA cards work but are restricted to PCI bus speed which slows them down to near unusable performance, and AMD cards present you with a Code 43 error and don't work at all.

The solution in that thread is in Russian on page 5 and google translate produces a response that's not quite intelligible.

What is the text?

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\AGP]
"102B0520"=hex:80,00,00,00,00,00,00,00
"102B0521"=hex:80,00,00,00,00,00,00,00
"102B0525"=hex:80,00,00,00,00,00,00,00
"10DE0100"=hex:00,01,00,00,00,00,00,00
"53338C10"=hex:00,01,00,00,00,00,00,00
"53338C12"=hex:00,01,00,00,00,00,00,00
"53339102"=hex:00,01,00,00,00,00,00,00

Please note that you do not have the .reg and delete it.

Change the driver to most PCI-PCI or use the AGP chipset on Windows 15 11 in package

C:\Windows\System32\DriverStore\FileRepository\agp.inf......

Has anyone gotten AGP working correctly with Windows 10 1607 or newer?

Well, it says to create a .reg file with the text below, and execute it:

1Windows Registry Editor Version 5.00
2
3[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\AGP]
4"102B0520"=hex:80,00,00,00,00,00,00,00
5"102B0521"=hex:80,00,00,00,00,00,00,00
6"102B0525"=hex:80,00,00,00,00,00,00,00
7"10DE0100"=hex:00,01,00,00,00,00,00,00
8"53338C10"=hex:00,01,00,00,00,00,00,00
9"53338C12"=hex:00,01,00,00,00,00,00,00
10"53339102"=hex:00,01,00,00,00,00,00,00

Then reinstall the driver for the PCI-PCI Bridge (that was actually the CPU-AGP controller) from your chipset driver, or from the following file of a Windows 10 version 1511 install:

C:\Windows\System32\DriverStore\FileRepository\agp.inf

What mean "limited support for nForce3" for Vista and above? It's reference to information from https://www.asrock.com/support/note/AM2NF3-VSTA.html#Phenom ?
And what it mean? Only specified cards will work, or all cards should work, but specified cards requires special treatment?
