To hardware-flash a BIOS chip, you need two main pieces of hardware: a Raspberry Pi and the appropriate Pomona clip for your chip. The Pomona clip actually clips over the top of your chip and has little teeth that make connections with each of the chip’s pins. You then can wire up the other end of the clip to your hardware-flashing device, and it allows you to reprogram the chip without having to remove it. In my case, my BIOS chip had 16 pins (although some X200s use 8-pin BIOS chips), so I ordered a 16-pin Pomona clip on-line at almost the same price as a Raspberry Pi!
