Hi. I bought a M/B from ebay. I turned on this motherboard. It asks for password. I shorted the cmos contacts while power supply is disconnected. Still, the request for password appears. I connected the BMA port to my firewall, and let the hoping the dhcp server will assign it an ip address, but the BMA's mac address is nowhere to be found. I assigned it permanently, still, it doesn't work. The motherboard reaches EFI shell though. Nothing else can be done. Any ideas?
