I made a similiar post about this in the Windows forums. I would like to have a deeper understanding of operating systems and all the components and processes that make them work. I have seen videos of Gentoo linux builds from scratch. However, I don't want to just follow a guide that would train me on the steps of building an OS. I would like to know what all of those components actually do? I want to know why and how it works on a foundamental level.
My question is. Can anyone point me to some really good books or videos that will help me understand this. I imagine this will be easier with linux than windows. Because you really can't build windows from scratch.
