Anyone with an x64 with an agp port feel like testing something?

Win10 2016 removed agp support.
As we all know, that should simply mean the drivers were removed from the iso.

So what I did was grab the drivers from 1507,rename one inf file to avoid overwriting and edit the other to match.

Theoretically, that should be all that's needed for 10 and 11 to re-add agp support. It also seems to have several references to Isa, so that may do something.

Details/method:
1 agp.inf points to several sys files and machine.inf
2 grabed those
3 renamed machine.inf to legacymachine.inf
4 edited agp.inf references to machine.inf
5 zipped

To test, 2 options.
1 Slipstream into iso
2 install fresh w10/11 and use device manager to update whatever the agp port shows up as.

In theory, everything that used to work should work again. I doubt Ms made any deeper architectural changes.
Agp is just an extended pci port, and pcie is a pci port with a serial layer 1. So it's hard to imagine removing support went too deep.

This would be a good thing to ask on hardware bot. A lot of folks there have agp 775 and am2 boards

I had trouble running these drivers because of digital signature issues. I could only install 1507 and then upgrade to 11 23H2.

It works, but it's very glitchy. I had to turn off windows transparency because I couldn't see the new UI at all. So even though it was installed in the end, I can't recommend doing it.

dont blame on this agp driver, its the fault of the last ever driver from nvidia that works with Geforce 6000 and 7000 on windows 10.

I get the same problem when i install in the igpu's (6150, 7025, etc), even when they are on pci express motherboards. It started happening on Windows 10 1909

Interesting. What were the signature issues?
Did I forget a file? Or do the signatures expire?
