Current BIOS version (from BIOS setup): P01.A3

Latest BIOS verson available: P11.A4

OS: Windows 7 Home Premium 64bit

 

BIOS update attempts fail with the following message:

   AMI Firmware Update Utility  v3.03.01

   Copyright (C)2012 American Megatrends Inc. All Rights Reserved.
   Reading flash ............... done
   3 - Error: ROM file size does not match existing BIOS size.

 

I run a current version check and get the following message:
   AMI Firmware Update Utility  v3.03.01
   Copyright (C)2012 American Megatrends Inc. All Rights Reserved.
   30 - Error: Problem opening file for reading.

    How can i understand which version i need to download?

    Laptop versions:
    1.xx can only be updated using 1.xx versions
    2.xx can only be updated using 2.xx versions (normally 2.xx version are labeled "not for upgrades")
     
    Desktop versions:
    P01.xx can only be updated using P01.xx versions
    P11.xx can only be updated using P11.xx versions (normally P11.xx version are labeled "*not for upgrades")

    "L" BIOS versions are Linux OS dedicated (example P01.xxL)
     
    * what does it mean "not for upgrades"?
    During the windows 7 to 8 transition, some PC models had different BIOS versions from factory, related to the installed OS.
    Windows 8 PC got an UEFI BIOS
    Windows 7 PC got a "Legacy" BIOS

    So PC with Windows 7 installed from factory can't use the "not for upgrades" BIOS version, even if they were upgraded to Windows 8 or 10, since the factory BIOS was a different version compared to PC with Windows 8 from factory.

    Thank you. There is no information in the downloads section to enlighten a seeker, so your response is appreciated.
