The process of replacing the motherboard began with removing the old motherboard. Now it's time to compare the old motherboard with the replacement motherboard to see how the physically match. I've pulled the I/O core shield out of the back of the case, and I've placed it on the I/O core of the old motherboard. You can see (if the flash isn't blinding you:-) that the old I/O core didn't have a game port or integrated sound, which the new motherboard supports. New motherboards should always ship with their own I/O shield, but with a second-hand replacement like we're using here, you have to make due. Fortunately, the old I/O shield has punch-outs in the proper locations.
