Academic research about ReactOS

Hi,

My name's Luis, I'm from Brazil and I've been interested in ReactOS for a few years (though not actively participating in the project). This semester, I'm having Operating Systems subject in my university (I'm doing a major in Computer Science), and I've chosen to make a presentation about ReactOS.

Where can I get documentation about the following parts of the ReactOS system, and, most importantly, its differences to MS Windows?

* Process management (e.g. scaling algorithms)
* Memory management
* File systems (it uses FAT, right? But are there any differences to MS Windows)
* I/O device management

BTW, sorry for my poor English and writing skills. :)

Thanks in advance and kindest regards,

Luis Andrade
