Back in the day, IBM published technical documentation (and assembly source? It's been a while) on the 5150 Personal Computer BIOS. The first PC clone BIOSes were created by having a team re-document how the BIOS worked from IBM's docs, and then having an entirely separate team create new code from that documentation.

How useful would this technique be to the ReactOS and Wine teams? Are there things that they don't know how to make work correctly that this source leak could help them with?
