This is very interesting. Would you be willing to share your expertise in how you got things working? We currently are using an Advantech SBC. But it has so much more than we require. This translates to additional cost we can't justify. (We use RTLinux to manage some sampling and closed loop temp control. It communicates to some system management code written in Java via a big chunk of shared memory. We did use FIFO's, but it was much too problematic when mixed in with the Java.) Doing a minimal system would be perfect. The only 'peripherals' we would add would be serial and ethernet. When you mention M=systems, are you referring to their flash IDE drives? Or some other flash based product. Which CPU are you using? The Elan? So many questions... :-) I gave up on this path early on. I mistakenly thought that we'd have to provide a BIOS. But I'm getting the message from your work that the minimal components required are: 1) A 386/486/... 2) A compatable interrupt controller configuration 3) Some boot device, i.e. flash ram 4) Some dram. Any info you can share would be very appreciated! Regards, Jim.
