The alarm processing circuit is for detecting the system errors using MDF accessing method and for alarming the errors by audible sound. The circuit comprises a power state detector for detecting the state of system driving power, a temperature detector for detecting the temperature of a system, an error input unit for inputting detected values, major and minor errors, and board states, an error cutoff selector for inputting error cutoff state signal, a decoder for decoding output signals of the temperature detector, the error inputting unit, and the error cutoff selector, a display for displaying output signal of the decoder, and an alarm unit for generating sound according to the output signal of the decoder.
