13.03.2009: In progress
Finding a PC with a proper LPT port could be challenging these days. In my household the only option was this headless Linux server. I had to use this guide to create a bootable USB stick with DOS and BD32 to flash the ECU while watching the progress on a projector screen, no less ;]

[..^ up ^..]

Here's a brief guide on how to connect a BDM interface to a Trionic7 ECU.

BDM (stands for Background Debug Mode) is an electronic interface for debugging microcontrollers and other embedded systems. It allows direct access to circuit components. In our case, we will be using it to overwrite the flash memory on the Trionic ECU. Normally, connecting via the CAN bus is a more convenient way to flash it, but if that process fails, you end up with a dead ECU. The only way to revive it is by attaching a BDM controller. Guess what happened to me ;].
