Enabling A20

[Triumph]

Hi!

Ive started this group of people, who would like to develop an OS over the next looong time
However, as ive been using Bona-Fide OS Development as documentation and tutorials for coding an OS, there doesnt seem to be any good tutorials for enabling A20, except copy+paste code.
And when i code an OS, i would like not just to know what the code does, but also how it works (What does the processor do, and how does it affect the code coming later on...?)
