MrRetroGamer Posted February 23, 2009 Share Posted February 23, 2009 From a very old thread: First, you have to disassemble the 5200. There are screws on the bottom holding it together (six or seven I think). After you get the screws out turn it back right side up and the top should lift off.Next, you will need to remove the RF shielding. Use a pair of needle pliers and bend up the tabs holding the top portion of the shielding. Once they are all straight, it should lift off. Next comes the actual chip removal. You will need to find the bios chip, it is labeled CO19156 on the 4 port and CO19156A on the 2 port. If I remember correctly, it should be located near the center of the board. Assuming you don't have a chip puller, you will need a small flat bladed screwdriver. Carefully insert the blade of the screwdriver under one end of the chip between the chip and the socket and pry it up a little. Now repeat in the other end of the chip. After a few times of repeating this, the chip should pop out of the socket. Check all of the legs of the chip and make sure none of them are bent. If any are bent carefully straighten them.

Wow, that's sounds so familiar, almost like someone pulled those thoughts out of my head. Mitch Quote Link to comment Share on other sites More sharing options...
