Got older hardware through the Sierra 10.12.6 install process, but no luck with old Nvidia GT220 video card. Only getting generic graphics.

Specs:

Processor: Intel Core 2 Duo E7500, 2.9 ghz

Motherboard: Gigabyte EP45-UD3L ATX LGA775 (BIOS)

Video: Nvidia GeForce GT220 <---only getting generic graphics

Audio: Realtek ALC888 <---not recognized

Wifi dongle: Linksys WUSB600N <---not recognized

Drive: 2tb SATA

RAM: 8gb DDR2

I've tried running with and without nvidia inject, tried a couple different versions of NVDAStartup.kext, tried telling Clover to use nvidia web drivers, all to no avail - still only getting generic graphics.

I thought it might be because I'm running the monitor through the VGA port and not DVI since the monitor I'm using has no DVI port, but to test this hypothesis, I hooked up another monitor that has DVI and it didn't change anything.

The last time I did a successful MacOS install on this machine, it was 10.6 or 10.7, and I've forgotten a hell of a lot of the basics, such as where relevant config.plist files are kept, how best to edit them, how best to install kext files. I installed TinkerTool and kextbeast, but kextbeast seems pretty clumsy and unclear.

Oh, it seems that the Clover USB key must be present at every boot of the MacOS now? Is there any way to remedy that inconvenience?

Thanks!
