    It;s RSA signed bios. Modified bios can't be flashed in any way

    Hi!
    ..I tried it on my own..and it WORKS! :)

    I modded the dump.bin with PhoenixTool 2.66 - Method - Module

    Serg008 may you could explain me short, what is the difference in the Methods Module or Dynamic?
    ..there are just minimal information around for PhoenixTool..

    thanks

    - Dynamic - an existing SLIC and any OEM/Table ID strings are updated
    - Module - a pubkey and marker are inserted as two new modules with a typical GUID. In addition for EFIs, if it is not already present, the SLPSupport module (GUID 4C494E55-5849-5342-4554-544552212121) will be added.
    (look Readme.pdf for Phoenixtool utility)

    add.
    As I said, I tried this method (from recovery) for R170D5 bios (Sony Vaio SVE1512H1RW), but with negative results - the modified BIOS was not flashed.
