Hi Stephan -

Using Flash Image Tool (FITC) to verify dumped data and comparing it with a fellow who has the same laptop and was able to dump their bios via spipgm.  Was hoping to get it working with bus pirate + flashrom combo.

Thanks!

How do you know that the chip contents are not all FF where you get
these results?
