From 5dd4a20b96f2bb563ae724c4eaf2524529bc46d0 Mon Sep 17 00:00:00 2001 From: Marc Jones Date: Fri, 20 Mar 2009 16:36:05 +0000 Subject: Add Supermicro h8dm3 mainboard. This is mostly a copy from the h8dmr. The one issues is the SPD address switch for the second CPU. That means that the memory must be an exact match on each CPU.
