I'm currently working on updating my PNY GTX 690 with UEFI support. I found a tool supposedly from Inno3D that allows you to do that, and after confirming with Inno3D that it is in fact from them, I'm going to use it. I've hit a snag though. Note that my card reports NVidia being the subvendor - it's the same for MSI, Galax, Zotac, ASUS, etc. cards as far as I'm aware.
The GTX 690, being a dual-GPU card, has a PLX switch on board. A PEX8747 switch. This allows both GK104 dies to have "full" PCIe 3.0 16x connectivity. To give the 690 full UEFI support, I'll need to flash three files - two for the GPU dies, and one for the PLX switch.
I can flash the GTX 690 dies fine, but I can't access the PLX switch at all - not through nvflash, not through the tool, not through GPU-Z, etc. I can't see the PLX switch at all. The only reason I know it exists is because I saw it on the PCB.
I also don't know how I would go about flashing a new BIOS file to it. Would I have to buy a CH341A or similar programmer, tear the card down, clip it on to the PLX ROM, and flash it that way? Or is there a piece of software that can do it that I can't find?
This brings me to my other question - where is the UEFI-supporting PLX ROM/module? I can't find it.
Why UEFI support? I'd like to turn off CSM. I don't need it to boot Windows anymore as I had to reinstall as GPT (my old install was MBR, upgraded from W7), and the only thing limiting me is my graphics cards. Turning off CSM will also fix the weird resolution I get while running OpenCanopy, the GUI for OpenCore (I Hackintoshed my computer). It's scaled weird and doesn't look right, and turning off CSM does fix this.
EDIT:
If you need more info I'm happy to provide, if possible.
