Android-x86 - Porting Android to x86
This is a project to port Android Open Source Project to x86 platform, formerly known as "patch hosting for android x86 support". The original plan is to host different patches for android x86 support from open source community. A few months after we created the project, we found out that we could do much more than just hosting patches. So we decide to create our code base to provide support on di

Motherboard Chipsets and the Memory Map
I’m going to write a few posts about computer internals with the goal of explaining how modern kernels work. I hope to make them useful to enthusiasts and programmers who are interested in this stuff but don’t have experience with it. The focus is on Linux, Windows, and Intel processors. Internals are a hobby for me, I have written a fair bit of kernel-mode code but haven’t done so in a while. Thi
