    It's just a question of interest: is it possible to integrate a bios password into the .wph/.rom file?

    Well the profit of this would be: if someone steals your notebook and removes the CMOS battery the password would still remain.

    They would just use fn+b to restore a regular bios..

    I think password is stored in another BGA (no legs) eeprom, not cmos like on regular desktop motherboards

    I think if eeprom has password, update any bios will still 'ask' for password.
    (unless that checked is patched, then you do an fn+b restore)

    You have to ask andyp for his "pheonix bios editor", 1.0 RC1 (not released yet so I can't comment, I don't have it also)

    He knows more about bios like Yen does..

    Thanks for the info.. but is the Fn+B a hardware thing or is it implemented in the BBL of the bios itself?

    Its the recovery bootblock, so its in the beginning *or* end of the flash chip.
    Software based.

    offtopic:
    I am also asking anyone with dead HP with defective nvidia chip to test if the Fn+B works or not.. if it works, someone can make a special bios that will allow it to boot off an external pci-e card,..etc
