Use the "TTAV" one. "readme-laska.txt" gives you a howto about creating nowhitelist bios from original Lenovo files. You can use it to create a patched bios image yourself (don't forget to share new nowhitelist bios to other people and update readme-laska.txt if needed)
A very big Thank You! Yup...just flashed my BIOS and it worked perfectly...my Intel 6230 is now working...now all I have to do is figure out how to enable bluetooth...
I have no idea how to turn it on/off in Windows. Windows is too complicated for me, so i use Linux. In Linux i just need to click on bluetooth icon in tray.
