Working on an Atom D500/NM10 system, trying to get some info on memory init. Everything seems to go alright up to when it starts pulling SPD data from the SMBus, but for some reason, the stock BIOS performs an SMBus read at 0x60, checks and sees that the read completed successfully, clears the success bit, and then, without reading the data, tries 0x64, and does the same thing. It then moves on to 0x9c, 0xd3, and 0xd2. I've attached a log file, don't mind my notes. Any ideas what might be causing this, and how to work around it?
Hmm could be probing to see if devices are present at those addresses? Is there anything there? Thermal sensors?
