TLDR In this article we will go through setting up paging structure and enabling protected mode with paging. This is not the same as segmentation in real mode. When paging mode is switched on, CPU will remain in segmentation mode. This segmentation is not used a lot today and long mode uses paging exclusively. After going through this process (and reading a bit of Intel manual) I hope that you will be able to set up 3, 4 or even 5 level page tables.via the TL;DR App
