Da habe ich noch was gefunden:
8. I have installed my M825L but it doesn't post or boot, nothing, why
Firstly check to see if the cmos clear jumper is set correctly. This gets most people. Also, the newer M825Ls have a socket labeled CPUPW1 which requires a Pentium 4 type power supply. Without a P4 PSU, this board won't even boot. This is the first AMD board I have heard of that requires a P4 CPU. The earlier rev 1.2a did not require this.?
