Hello, I have a OutBack Guidance S3 GPS system for farming that I corrupted the bios on trying to update it. It runs Windows XP embedded and their is zero support for the S3 systems anymore. I have an identical one that works, how can I copy the bios from the working on to the old one. The only way I can communicate through it is with serial port. Keep in mind, it has a complete custom motherboard that I don’t have access to any parts for and no information for on the internet. I would just re flash the bios chip with the original BIOS, but that file is no where in existence since the company stopped supporting it many years ago. Any help would be great!!!
