Serial Flash Memory Chip

The 24C02 is a serial flash memory IC manufactured by many firms such as Samsung, National Semiconductors, and Atmel. As a result there will be a prefix code to the chip, KS for Samsung, BN for National Semiconductors, and AT for Atmel. The last two digits represent the memory capacity in kilobits; and they can be 01, 02, 04, 08, and 16. This chip comes in many packages such as TSSOP8, SO8, and PDIP8 to name a few.

This is an 8-pin PDIP package. Simply solder a wire to pin 3 and another wire to pin 6. Temporarily join these wires whilst the laptop is booting to bring it into manufacturing mode, during which time it will allow access to the BIOS through the BIOS Setup option.
