After reading this page  I understood why my monitor doesn’t “show” image until the OS has booted. Is there some tool for Linux that does the same job as the page says? I’d use nvflash to do it, but not sure what BIOS I should use.
I currently have a GTX 970 with vBIOS 84.04.1F.00.2A
Unlikely. You probably just have an integrated intel gpu that’s still enabled as primary graphics adapter. You would then have to connect a monitor to it, enter bios and disable it or set the pcie graphics card as primary.
luckily i have a dual monitor setup where the second one is connected via DVI, which doesn’t have any problem. Still, I would be nice to have this firmware updater/tool available on linux.
they have a big collection of bios files.
Yeah, just need to find “the right one”
None will be right, the firmware patcher was released 2018 and there hasn’t been a firmware added for the 970 since then, so no patched firmware available.
Well, that’s part of the “why” I came here to ask. Maybe they can develop or somehow provide a firmware for the cards.
More, afaik, that site provides the bios files that were uploaded by users, so, maybe no one updated their card and dumped it and uploaded to the site. ;)
