So...if you are trying to run a four-chip solution, you may be disappointed. So far, no one has had luck with it. I have the chips on hand to debug this, but I haven't had the time to build a slug with them. I don't think that the memory bank size is really important as the sdram init code is supposed to figure that all out. Tell me exactly how your hardware is put together. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
