Also, do you, or anyone know anything about the pci-device_10de_0141.fs?

I have one of these cards( Geforce 6600 ). It’s an Apple OEM with an nVidia Fcode Option Rom. I am trying to enable it for PCI Passthough, mostly for Openbios so I can use it in the Mac OS, however I have Fedora 27 installed in a qemu pseries power8 virtual machine, and the GUI is tearable slow, so it would be nice to get a little graphics accretion working.

Tho for linux, the nouveau driver will let me load the PC Bios option rom for this device, and I should be able to get it to work that way, even if SLOF doesn’t.

Just poking around in the code for SLOF, it seems there is some support for reading the option roms of pci devices, and when I look at the properties of my card, it seems at least the rom gets an address, but it doesn’t seem SLOF is trying to use the Fcode off the card at boot time.
