    HP has started shipping a new model for the DM1Z Zacate-based netbook, model release 3200.
    This comes with Insyde Bios vers F.12

    It seems that in the process they have disabled access to the Advanced Bios mode, usually triggered via F10 followed by A at boot time.

    I suspect that they disabled the F10+A key combination but there is another one, if only for their support technicians.

    My questions would be:

    1) Are there other "known" key combinations to trigger the Advanced Bios for Insyde?

    2) Are there tools/techniques to scan a Bios binary file to "discover" unpublished key combinations

    3) Is there a third party tool that would allow us to flash a prior Bios version? (the HP tool does not allow downgrading from F.12)
