    Hello.
    Tell me what to do.
    After modifying the BIOS from Insyde, a proprietary tool from hp refuses to write it back, ending with an error rsa-signature.
    How to package a modified BIOS to the image suitable for firmware?
    Thanks.

    (OP)
    Netbook HP Mini 210-3001er (with disabled VMX bit) :(

    Decrypt of the original image is produced by setting an option in the configuration file platform.ini utility from HP.

    >[BackupROM]
    >Flag=1
    >FilePath=c:
    >FileName=image_old.bin

    To unpack the binary image ROM-files I used phoenixtool.
    Next, I made the necessary modifications to the code (msr register 0x3a), but after unloading the modified code, the utility of HP firmware fails RSA signatures.
    Tell me what to do?
