Weird, I've never seen that problem. Do you have any other dram modules
you can try? Can you send me the specs (or a link to the datasheet would
be best) on the module you're currently using? I have some comments I
need to put in about some important bits, but haven't had the time or
ambition lately to do it. Eventually those bits should be set up
automatically, but I'm running up against ROMCC's limitations.
