It's possible that there is a mux in the way that needs to be set up correctly to allow you to read the DIMMs on the other CPU. > If I move all four DIMM's to CPU0 then coreboot detects 2GB but > hangs when initializing the memory. That sounds like a different problem. Maybe the mux idea isn't right. > The same thing happens if I use two > 1GB DIMM's. I'd start by enabling the debugging output CONFIG_DEBUG_SMBUS. I haven't had to dig very much in that part of the code. Thanks, Myles -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
