Chris, I tried to read the printing on the processor chip. it is not
readable, processor is soldered to the downside of the board...

the BIOS summary tell that I use a Intel ATOM Z550, the modell is a
POKINI Z manufactured by exone company. ( the current description
from the internet tells the the pokiniZ has a ATOM Z530 build in).

I hope this helps.
regards
hjl
