AMD GPU dual-bios, one won't boot.

[MrN1ce9uy]

Got a new Sapphire RX 570 8GB Nitro+ Hynix card yesterday. I flashed the bios and now it won't boot. The flash was successful. I can switch bios and it will boot. I can then switch back to other bios once booted, flashed original, but still won't boot unless on unflashed bios.

I did get a message saying bios is too small when saving it for the first time. I've seen that before and didn't have this issue afaik.

Any help would be appreciated.

You might be using an old version of Polaris bios editor. Try the one below. Also, backup the working bios or use the one you backed up before flashing (if you did) and reflash it.

Boot into windows with the working bios, flip the switch yes with windows running and flash with the working bios.

That may be true, I'm using Polaris Bios editor from almost a year ago.

Btw, I don't see one below.  

*Edit: I downloaded a new version (Aug, 2017) and it's working.

Thanks!
