Hi Ward

Thanks for your updated build description on the wiki. I think there is a list 
of build instructions on the list, where your description is not linked?

Also the description of the filo payload still postulates that filo doesn't 
load sata disks. Which it does according to your build instructions.

I know i am a little biased... :-) but i think my proposed solution has some 
advantages over desoldering the flashrom. First desoldering with a heat gun 
poses the risk that you simple blow some of the tiny resistors away and 
second it is pretty easy to switch between the two flashroms which is quite 
neat in comparing register settings...

I think thats inb for byte access and inw for word access (16 bit). You need 
to be root to do this though. The addresses can be taken right from the
