How do I start learning how to use Protected Mode (32-bit)?

Question about which tools to use, bugs, the best way to implement a function, etc should go here. Don't forget to see if your question is answered in the wiki first! When in doubt post here.

  • Drive number in register DL is saved to an undefined memory location (segment register DS).
  • Direction flag is undefined (STOSD and LODSB).
  • A20 enabling strategy should be reconsidered.
  • DAP should be aligned.

Not to sound like a broken record or anything, but I still would like to know which wiki pages (or any other sources) Starmanz was referring to. We already know that the wiki has problems with lack of clarity in many places; knowing what is leading the OP astray might help us pin down and fix some of that.
