Hey svl7 thank you so much for all your effort so far! I bought myself a Y580 last week with no OS pre-installed, the BIOS version it was shipped with is 2.0.7. I know someone already asked for a modified version of 2.0.7 a week ago, I just wanted to check if you found the time of doing a modified version or if you are still planning on doing so? Thanks in advance! Edit: I flashed the "Lenovo_Y480_Y580_-_BIOS_V.206_[unlocked][no whitelist]" BIOS and my Intel Ultimate-N 6300 was working just fine. Yet I sadly had big problems with the NVIDIA GPU: - The NVIDIA driver and 3D programs kept crashing constantly - Artifacts in 3D scenes After flashing the modified BIOS I just loaded the setup defaults and didn't change anything. Anyone else experiencing similar problems? After reverting back to the stock Lenovo 2.0.7 (5DCN40WW) BIOS everything was working just fine again.
