    All links to already patched Lenovo T410s bioses are dead.
    So i tried it myself, using Yen's instructions.
    But i get an BIOSBOD06.ROM the same size (according to windows explorer both files are 56.651 Bytes) with some changes:
    Offset old -> new
    2B7A: F9 -> EB
    2B7B: EB -> 01
    2B7C: 06 -> F9
    Sadly Andy's PhoenixTool 2.7.3 failed to integrate BIOSCOD06.ROM "New BIOSCOD06.ROM Module is 3 bytes too big".
    What's the trick? This bios got already modified successfully.

    Thank you, Serg008 !
    Do you have an idea, why it doesn't work for me? I followed Yen's instructions, and i have checked: both files, old and patched, are equal size, unlike andy's PhoenixTool said, the patched one "3 bytes too big", that's not true.

    The original module size never changes since we patch some bytes to have other code like conditional --->unconditional jump, for instance.

    If the module is originally compressed, though, it can happen that the compressed size of the patched module is bigger now.
    Andy's tool reintegrates the module compressed when its originally compressed.
    At this particular module the patched and compressed module is 3 bytes too big and does not fit anymore.

    As solution you need to alter additional bytes (data, best some ASCII) to make it more compressible again.
