Flashrom v0.9.6.1-r1564 BIOS reading fail on HP EliteBook 8560p
by Marc-Alexandre Espiaut 30 Nov '12

30 Nov '12

Here's the log you're asking for. I haven't installed dmidecode since it prevents flashrom from running on a laptop for security reasons. Replacing the current BIOS on this laptop would be a blast. HP/Compaq BIOS prevents the user to change the hardware to what they want. For exemple, replacing a Mini PCI-e Wifi card that requires proprietary drivers with one that can use FOSS drivers. Hope that helps, feel free to contact me for further informations about my laptop. Regards, Marc-Alexandre Espiaut

Ok thanks for the info. In my case the BIOS file is smaller than the chip size. So I need to blow it up. Are there some information about that somewhere? I couldnt find anything?
