I have an M5-581TG. Its BIOS version is 1.12. I found in the support section there is a new version 2.11. Its description says "BIOS - UEFI for Windows 8 (Not for Upgrades)". I don't know what it means. I'm not running Windows 8. I am running Windows 7 and soon will upgrade to Windows 10.

 

The question is : should I install BIOS version 2.11? Thanks.

    You can't mix BIOS versions.

     

    BIOS 1.x can be updated only with 1.x BIOS versions

    BIOS 2.x can be updated only with 2.x BIOS versions

     

    not for upgrades, means: if your system has windows 7 from factory your BIOS is 1.x and can't use 2.x BIOS versions.

     

    Windows 10 can run also under BIOS 1.x
