【 BIOS Chip Connection Method and Chip Pin Map 】: Because the BIOS chip of a tablet is not directly plugged in and out like a desktop computer, it is important to pay attention to the corresponding pin positions when connecting the BIOS chip with the SOP8 test clip. Reversing the connection and burning the chip will not be worth the loss. The BIOS chip of this machine has a pin with a small circular dot on pin 1. Generally, there is a colored wire on the test clip cable, which is the first wire. Let this wire correspond to pin 1 of the chip. This way, only check whether pin 1 on the test clip and the programmer correspond to each other to ensure accuracy. Attention should also be paid to whether the pins on the test clip and cable connection adapter board are plugged in correspondingly.
【 Programming software flashing BIOS 】: After confirming that the chip is connected correctly, connect to the computer. Open the programming software and check if the chip information has been read. 2-- Erase, the process is slow, taking several tens of seconds. 3- Check empty, confirm empty. 4- Open and select the bin file. 5- Programming, about a few minutes. 6- Verification is required.
After completing the above steps, you can solder on the power supply and turn it on to check. When there is no power, a few lines of English letters will appear, which is also successful. After charging for a while, it can be turned on normally and enter the system normally.

Operation process of 341A programmer
Do not activate the software automatically, manual operation is required
Firstly, identify the chip model
2. Click Read again to save the program in the original chip that needs to be retained.
3 and then erase
4. Open a new file again
5 clicks to write (programming)
After writing the entry, the software will automatically validate it
Just close the software or unplug it directly
