[flashrom] IBM SurePOS 700 4800-783 support

[Jason_Vannest at abercrombie.com]

Sorry if this is a flashrom noob question.  But I want to make sure that I 
understand correctly what your saying.

It sounds like this Renesas H8S2116 controller is something that nobody on 
the flashrom dev team has worked on yet?

>From reading your very fine and very detailed web site (congrats on that 
BTW), specifically the section on adding support for laptops "
http://www.flashrom.org/Laptops" it sounds like a little bit of a 
challenge to add support for a new chipset like this?  Is that a correct 
assumption on my part?

We've spoken with IBM and of course all of their current stuff is DOS 
based / bootable from USB key.  Of course for a fee they would be willing 
to help us out and develop a Linux based program to update the BIOS..... 

Does anyone have thoughts on how much time and effort it would take to do 
this?  IBM is hardly ever the cheapest solution, so I'm guessing we would 
more likely find a more reasonable price from the Open Source 
community....

Thanks again for your assistance.

So the chipset in your POS machine is, at the moment, not recognized by 
flashrom.

Note: flashrom can never write if the flash chip isn't found 
automatically.

According to this IBM web page [1] there is a "Service Processor Renesas 
H8S2116" [2] present.
