Boot into windows, install this driver.
Download NVidia driver from their website for your gpu, do not install it yet.
Disable Windows update. Shut down.
Plug in Amp. Turn on PC.
Boot into Windows. You should see Microsoft Basic Display Adapter in divice manager.
Install the Nvidia driver. IIRC, the AGA will not show up as a device in device manager, just look for the display adapter and make sure it is running correctly.
I'm not sure it can function with a dead 1060 though. Could be some underlying things the 1060 would still assist with, but I am not sure.
Highly suggest you sell the laptop, AGA, and GPU and put them towards a new laptop. 3060 laptops start at $1000, between the 1660S, AGA, and moderately functioning 13 R3, you can easily be over half way to the new laptop. 2060 equipped laptops were $600 just this week, so that is an option too.
