【BIOS Chip Connection Method and Chip Pinout Diagram】：Because the BIOS chip of a tablet is not as easily removable as that of a desktop computer, it is very important to pay attention to the correct placement of pins when using a SOP8 test clamp to connect the BIOS chip. It's not worth the risk of reversing the pins and damaging the chip.The BIOS chip of this machine has a small dot on pin 1.There is a colored wire on the general test clamp line, which is the first wire. Match this wire to chip pin 1, and then it's fine to just check if the 1st pin on the test clamp and programming device matches. This ensures accuracy.When testing the connection of the test clamp to the connector board, it is also important to ensure that each pin on the connector board is correctly plugged in.
