hi just thought I would help im a newbie as well I have only just started to figure out some of the MBM settings my self is that the line from MBM3 in the LCDC setup menu which refers to AMD ?, I have the same CPU all I did was change the line to read P4 seems to have worked, its well worth popping back into MBM5 to make sure you have assigned the CASE /CPU correctly for your second question
I hope this helps
