Hi there. I've been thinking about flashing your BIOS, but I have one doubt. Is the BIOS version kinda related to a OS ? Do I need a special BIOS version depending what OS version laptop i got ? I see there are two basic versions: 2.0x and 8.0x I don't want to brick my laptop so I need to be sure. I've got 2.07 BIOS (from Lenovo website) and originally my Y580 was without an OS. Now I am on Windows 8.1, So what BIOS version should i flash ? 'Lenovo Y580 / Y480 BIOS v2.07 (5DCN40WW) -> unlocked, whitelist removed, Nvidia 660m @ 1GHz default 3d clocks,' this one ?
