Motherboard layout with the BIOS chip shown in the upper part of the picture
Replacing the Basic Input Output System (BIOS) chip on a CI56 helps when there are unexplained errors occurring on the system that involve known good components that function improperly. The BIOS of any computer allows the basic hardware to interface with the operating system during the initial boot phase. This function is replaced by operating system drivers once the computer has booted and the drivers have loaded. The BIOS often gets updated, and occasionally during the update procedure, a problem occurs with the BIOS that requires the BIOS chip be replaced. Static electricity can also cause severe BIOS damage.
Instructions
1. Create a full backup of your computer to an external optical disc, a USB Flash drive or a network location.
2. Power down the CI56 computer system, and disconnect the power cable from the wall.
3. Remove the case cover, and attach the alligator clip end of the anti-static wrist strap to a portion of the metal case that has not been painted. Connect the other end to one wrist.
4. Insert the chip puller under the surface of the BIOS chip on the motherboard in a way that seats the pulling surface of the chip puller fully under the edge of the chip. Ensure a tight connection by gently squeezing the chip puller together toward the edges of the chip, and then pull the BIOS chip out of the socket in a slow, steady motion without tilting it in either direction.
5. Install the new BIOS chip into the socket as indicated by the Pin 1 notch cut into one end of the chip. It's a small, U-shaped depression that matches the shape on one end of the socket. Or align Pin 1 as marked on the chip with Pin 1 as marked on the socket.
6. Press the new BIOS chip slowly into the socket, being careful not to bend any of the pins on the chip. Push firmly until the chip is fully seated.
