    Just downloaded the oldest BIOS and the newest BIOS of 6730s and they do both not have double SLIC entry. Additionally these are EFI BIOS and may be completely different from the BIOS we are trying to update.

    hi,

    Yes EFI bios's are out of scope.

    The memory patch will not work, as by then the flag had already been read by the flashing program.

    And the "downgrade" also must be possible (after all the newer BIOS did NOT make changes to hardware!, it is still the same), it must be another flag or date inside the .bin file

    So it is "only" to find what it is... (easier to say than do)

    Something like a HPIB103 Hewlett-Packard Interface Bus ?

    hi guys,

    many thanks to you for learning a lot of bios during the last day while reading your posts for finding a solution for my hp 8710p.
    But now I tried wow7, it worked and w7 is activated.

    But for me is still one question - why don't you succeed with SLIC 2.1 for hp 8710p bios F.0F and wow7 does it?

    If I understand corectly with a loader the bios is still SLIC 2.0, the loader just POKE the memory on the fly , you you have a virtual 2.1

    It is like asking why the sun is yellow.

    WOW7 is software only mod, BIOS mod is to write the software (.bin file) to the hardware (BIOS chip)

    And this last action proves impossible so far with HP Business laptops (some of them)

    the MODDED BIOS of HP must be packed to .cab before flash.
