If that is the model number, it is probably a Lucky Star. The manual can be downloaded from http://www.lucky-star.com.tw/technical/manual/intel.htm#SLOT-1%20M/B. I think they could do with a better translation:
On power on, the system make beep sound to offer different messages. If the system is configured correctly, it prompts a short beep to show correct the devices configuration is done correctly. When VGA card and DIMM modules are not plugged well, the system makes longer and constant beep sounds. "
