FOSDEM 2007
At FOSDEM 2007, Aleksey Bragin made an appearance to represent the ReactOS project. While there was an introduction to the project, the presentation focused on the ReactOS kernel and boot loader (FreeLoader). In the presentation, Bragin discussed the parts and procedures of the kernel and boot loader, placing emphasis on the compatibility (or lack thereof) to the Windows NT implementations.
A video of the presentation is available here.
