The present invention discloses a debugging device using an LPC interface and capable of recovering the BIOS functions and a debugging method therefor. The debugging device comprises a firmware hub, an LPC interface, a decoder, and a display unit. The LPC interface electrically connects to the decoder, the firmware hub, and a computer system. The decoder receives a POST code of the computer system to monitor a startup state of the computer system through the LPC interface, and then decodes and provides the decoded POST code to the display unit for showing every startup step of the computer system. When the original BIOS of the computer system is damaged, the firmware hub provides a backup BIOS for the computer system to start up, and recovers the original damaged BIOS. The present invention improves the stability of the computer system, and saves the cost and time of recovering the BIOS.
