I'm attempting a Coreboot port to another Poulsbo board (the Kontron nanoETXexpress-SP) at the moment, so I've been following your thread with great interest. So far I've had about as much success as you, though. Svante Ekholm M.Sc. student, Uppsala university, Sweden. Located at CrossControl, Alfta, Sweden.

Hi all, I am sorry that this could look like a double post which I asked under the "Getting serial output from w83627hf?" topic but couldn't get any reply. So I thought it is better to ask it in a separate mail, being really a different matter. Well, I need the Intel System Controller Hub(SCH), Chipset Microcode(CMC) state machine binary as it is stated in the src/southbridge/inte/sch/Makefile.inc file as: #We don't ship that, but booting without it is bound to fail So how can I get this binary? Does it lay in the proprietary bios that I can extract from maybe? There is something I didn't get as well, is it the same thing with the CPU Microcode? (I have Atom Z510 processor) I did lots of googling but couldn't find it:( would be grateful if someone can help on this. Thanks in advance, Alp
