EEPROM 3 read/write methods:
1. Directly desolder the chip from the motherboard and solder it onto a small board (the purple dot is the chip position; the six solder pads can be soldered in any position, but only one chip can be soldered at a time). Connect the small board to a box via an extension cable, then connect the box to a computer. Use software to read, erase, and write data.
2. Jump wires from the points on the motherboard to the numbered positions 1–6 on the small board to read, erase, and write data.
3. Without using the small board, directly solder six wires (the red wire is the first from the left, numbered ④) to the test points on the motherboard according to numbers 1–6 to read, erase, and write data.
