Hi! Where I can get low-level info about so-called "Long Mode"? I need descriptor table specs, virtual-to-physical address conversion scheme an so on - I'm going to plan my own little 64-bit OS for memory test purpose.

Check out the AMD64 Architecture Tech Docs:

They include a bunch of programmer manuals that may contain the info you are looking for. You can download the pdf's, or order them online.
