Hi, have a problem to update bios on Aspire L5100 (sn 92GJG9ZR7P8120971F2707).

Current bios version is R01-B0 (01/29/2008). I have download actual bios from https://www.acer.com/ac/en/GB/content/support-product/337?b=1 R02-A1 (09/12/2008). But when I run the included winflash utility, and select the bios file, I get a "Please select correct BIOS" message! 

Any ideas?

    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:
    R01.xx can only be updated using R01.xx versions
    R02.xx can only be updated using R02.xx versions

    "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.
