This is supposed to be a guide as to what hardware and what configuration was common for a given year. This is a work in progress and if you don’t agree with a specific configuration, please let me know. Each year shows an entry, mid- and high-end system configuration. It could be that the hardware listed was released at the beginning or at the end of the given year. So, it is not an exact…
Do you need help splitting BIOS files (Even/Odd or High/Low)? Do you need to combine two files into one? Or do you need to double the size of a BIOS image to fill the entire space of your EPROM chip? Then you can try one of the following tools! The tools are written in JavaScript and run in your browser.

The below list should aid as a lookup for anyone who needs to understand what device and model is behind a given Device ID. I also added a fuzzy search that also allows you to filter chips using regular…
