I just happen to have 2 machines on my home network that are Intel D525MW motherboards, with dual core intel atom 1.8 GHz cpu's. They run flawlessly from powerbump to powerbump, on an rtai patched but now elderly kernel, a kernel that says its for an i686-pae. Not an AMD64. gene@shop:~$ uname -r 3.4-9-rtai-686-pae gene@lathe:~$ uname -r 3.4-9-rtai-686-pae This kernel is in fact not a pae kernel, because the rtai patches disable that, we found that out after the fact, but those 2 machines only have 2GB of dram, so the lack of pae is moot. Enabling pae on those wrecks the context switching latency anyway. And that is far more important for what they are doing (running linuxcnc) than anything else they may be asked to do. Yes, they are also 32 bit kernels, again because the context switch time for a 32 bit kernel is 1/2 the context switching time for a full 64 bit kernel. So its possible we may be compareing apples to oranges. What is for sure is that this mobo is the fastest mobo ever to come out of silicon valley for running linuxcnc, by a factor of at least 2/1 over the next best. I would have several more of them if Intel hadn't disco'd it about the time it was discovered by the linuxcnc people. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
