If there were the official one, we wouldn't install the leaked beta You should be able to download it now as you have 7 posts.

I don't know, I asked the same question because there were many people in this thread who had problems after installing the unlocked bios ver 8.xx. I think it could be safe to install the unlocked bios ver 8.00 not 8.01. Can someone confirm that? The solution is few posts back: http://forum.techinferno.com/lenovo-ibm/2260-lenovo-y580-y480-unlocked-bios-versions.html#post69650

So firstly you should install the unreleased beta bios from here: http://forum.techinferno.com/lenovo-ibm/2260-lenovo-y580-y480-unlocked-bios-versions.html#post65166

If you install the unlocked BIOS, you can enable the virtualization in the BIOS. Yes, it's safe to flash that bios over original 2.07 bios and it doesn't matter whether it's i5 or i7 laptop. There will be no problems if you have the original WiFi card. Which version of BIOS do you have?

Yes, it's 100% safe. I've just used this beta to update my unlocked bios (2.07). Now I have new options in bios regarding the Safe Boot and few other things. In order to get rid of the safe boot message you have to choose the option "reset to factory key" in bios and of course have the Safe Boot and UEFI enabled. After a reboot you should have the Safe Boot status in bios changed to "enabled". The other good news is that now the laptop seems to start faster and there is no Win8 loading screen but a Lenovo logo. Unfortunatelly there's a white list again, no GPU OC and no advanced settings in the BIOS. So I have a question: is it safe to update this beta BIOS to the unlocked bios ver. 8.00 from the first page?

So nothing new with update from BIOS ver 2.07 to 8.01? I remember the OP asked if someone wants to test it.

I'm interested because I'm using Win8 with bios version 2.07.

I'm also interested (bios 2.07).

If you already have installed the 2.07 bios without mods you have to change the last word in the third line of the file "platform.ini" from "RESSEN" to "RESSDIS".

I found out that the Intel VGA BIOS in Y580 is outdated. I have a version 2137 but there's a new bios from January (version 2158) here with instructions how to install it. Is it possible to include this in modified bios?
