When GRUB finally loads a kernel, I found put that the CPU is using already using 32-bit flat addressing and all segment registers start at 0 and have limits of 4GB - 1. I also was able to find out that paging is not enabled. Right now I'm wondering what mode the CPU is in once control is passed over to the kernel. I could check the PE register but right now I'm at work and wont be able to get back to my dev system until Wednesday evening... Thanks

32-bit protected mode
You should reload the GDT, however... use your own.
And the IDT isn't defined at all, so you'll have to do that as well.

Cheers,
