commit b2200da8136df56b0093cf6655423d0205b3aaf4 Author: Elyes HAOUAS ehaouas@noos.fr Date: Sat Jun 14 20:17:49 2014 +0200
New Board based NEC ECS 945G M4 (LGA775 i945GC i82801gx w83627ehg)
some changes on raminit.c in order to have all DIMM detected "properly".
To Fix: The system hangs on ERROR: CBMEM was not initialized yet. Could not migrate CAR data! ( please see http://pastebin.com/VbigRjfQ )
