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
