    billdh2k,
    I'm sure not.
    Your assumption about tools needed is also correct.
    I don't think that old 775-socket boards are UEFI-compatible, that is why you need MMTool v3 or other similar utilities (depending on original BIOS vendor, which is not Intel AFAIK) to work with them.

    Thank you CodeRush. At least there is hope o_O. Saw some YouTube videos on SPI programmers, in process of figuring out to build Arduino or buy from China. Am good with building electronics components. Too much effort for changing 1 byte of code though :confused:.

    Edit: Under $20 for clip and programmer shipped on ebay. Buying it is but a month to receive it.

    keepclubbin, it's normal to have this type of errors, no reasons to worry.
    g5, you need unpacked version of exe file, then run extractor from commandline like this "extractor iflash.exe bios.bin", if bios.bin file is produced - it's your extracted image.

    Thanks for replying. I'm still having problems. when i type in
    "extractor iflash.exe bios.bin" i get "input file cannot be open no such file or directory".
    But when put in "extractor insydeflash.exe bios.bin" it says "Insyde BIOS image signature not found in input file"
    Is my insydeflash not compatible?

    It isn't possible to decrypt 2nd gen RSA encrypted HP bioses yet.

    Hi Tito,
    this is not properly true as there is a way to Decrypt HP RSA Sign Bioses 1st and 2nd :

    Flashing Original Bios It leaves always a Decrypted copy into HP_BOOT partition

    The problem is to re-Crypt It, but seems that Donovan has got a solution !
    Regards

    Yah I know. But I'm talking about our own de/encryption routine; without using HP's flasher. For example, it is impossible to get the decrypted bios on another PC because it can't be flashed on that one.
