Ideapad Z580 Windows 8.1 64-bit BIOS version

I have a lenovo Z580 pre-loaded with Windows 7 Home Basic that I upgraded to Windows 8 around 2 years back and then subsequently to Windows 8.1. Yesterday, I saw that the page for my product was showing a BIOS update for Windows 7 and 8. Thinking that it would run on Windows 8.1 also, I downloaded it and installed it, but alas I was wrong, and as soon as the update happened my system stopped booting and was stuck on the boot menu and kept on asking which device to boot from. I then changed the Boot Mode from the BIOS to Legacy and was able to boot into the system, but as we know the boot process becomes slow. The new BIOS version 5FCN95WW. While updating I did not take note of the previos BIOS version and nor did I take a backup of it. If anyone has the same specification as my laptop, please tell me the current version of BIOS. And also if you have not changed your BIOS version please upload a copy of your .WPH file.
