As shown in the drawing, use an ROM extractor to clamp both sides of the ROM, then pull the ROM upward vertically.


This should be done very carefully to avoid bending the pins of ROM. If the pin of ROM was carelessly bent, use a pincher and bend it lightly back to its original vertical shape.

    

After taking out the ROM you can see that there a half-moon dent at the exposed side of ROM socket that is the same as the half-moon dent of ROM indicating the direction.

Or use the asterisk symbol on the sticker on RD1 as the direction of key.) Install the key of RD1 at the same direction as the key of socket on the motherboard. Pay attention to both sides of 16 pins and make sure that all the pins are inserted in the socket.

If you cannot locate the half-moon mark on RD1, locate C2. The half-moon mark is beside C2. Make sure that the 16 pins at both side of ROM should be totally inserted in the 16 pins at both side of RD1.
