Re:kernel development
imho, the most interresting stepping is:
1. make sure you have a working IDT, with handlers for both common interrupts and exceptions. Also make sure you have enough information displayed on exceptions (kind of "panic" message).
2. give your kernel a small memory allocator so that you can more easily create and manage dynamic variables.
From there, it's up to you to define if you want to continue with multitasking, devices like floppies and hard disk, etc. But i would say that the earlier you'll introduce multitasking, the cleaner it'll be.
