How I Built a BIOS Programing Tool for Any Motherboard (SPI/TPM Method)

In this video, I show the custom tool I built that allows you to program or flash a motherboard BIOS directly through the TPM or SPI header.
This method makes it much easier to recover dead boards, fix corrupted BIOS chips, or update firmware without removing the chip.

I walk through the full build, wiring, pinout, testing, and a full BIOS programming demo so you can see exactly how it works.

🔧 What’s Included:

Why I built this tool

Understanding TPM & SPI headers

Wiring and pinout explanation

Connecting to the BIOS chip safely

Flashing a BIOS using an external programmer

Testing the board after programming
