Mainboards where the BIOS chip is soldered onto the board (and not in a socket) are usually problematic for coreboot developers and especially users, as one incorrectly flashed image will render the board unusable.
Requirements
- A board with soldered-on (PLCC) chip
- Soldering iron
- A PLCC socket (SMD type)
- Desoldering station or heat gun
- Tweezers
- ...
-
...
Preparation
- Take a picture of the board and ROM chip. You might need that later in order to add the socket in the correct orientation.
Desolder or cut away the ROM chip
Clean the pads on the board
Prepare the PLCC socket
