Dear all,
I successfully flashed a notebooks GPU BIOS SPI Flash Pm25LV010 using flashrom. I don't know why but I used Flashrom 0.9.4 and not the latest one and therefore had to add the WREN feature flag that is already present in 0.9.7.
I used the bus pirate with 120kHz SPI mode.
Notebook is fine again and a friend of mine happy :) (He flashed some non-mobile gpu bios from within windows using another tool... Don't ask)
Regards,
Matthias
