I'm trying to set up my MAME PC, and am having a problem with the motherboard. Its a SuperMicro P4DC6 with dual Intel Xeon processors. When I turn it on, four small red LEDs light up on the motherboard, and I get a repeating tome out of the PC speaker. The best way I can describe it is as a "dee doo dee doo dee doo dee doo" sound. I never actually get any picture on the monitor. I did test the video card on another computer, and it works.I have searched google to no avail. Any ideas?
