Fixed bug in GDT length calculation in bootloader. Kernel now loads its own GDT so it doesn't clobber itself while touching memory. ATAPIO now loads its own copy of the boot sector so it isn't reliant on 0x7000 being mapped. Removed debug printf statements from a lot of places.

Fixed paging fully now. Kernel is loaded with virtual memory enabled. Just need to write an allocator and make kernel use virtual memory addresses for its stuff. Restructured codebase to be less messy. Updated Makefile to put binary files under build/ rather than in root directory

Completely changed how XnoeOS boots, organised the code somewhat, renamed kernel32 to kernel, now uses the 9 sectors after the boot sector to store a 32 bit stage2 loader. No longer spends unnecessary time in real mode. Updated atapio to properly account for the reserved sector count.
