After a MENMON update, the hardware revision displayed by MENMON will most probably be different from the actual hardware revision of your CPU board, because MENMON follows duagon's hardware revision updates.

• Unzip the file "menmon_EM3.zip" into a temporary directory.
• Connect a terminal emulation program with the COM1 port of your target board and set the terminal emulation program to 9600 baud, 8 data bits, 1 stop bit, no parity, no handshaking (if you haven't changed the target baudrate on your own).
• Power on your target board, and press "ESC" immediately.
• In your terminal emulation program, you should see the "MenMon>" prompt.
• Enter "SERDL MENMON". You should now see a "C" character appear every 3 seconds.
• In your terminal emulation program, start a "YModem" download of file "menmon_STD.smm" (for example, with Windows Hyperterm, select "Transfer|Send File" Protocol="YModem").
• When the download is completed, reset the target CPU board.
