exDOS

I decided to write an operating system from the ground up,  
in x86 assembly and C.
 
The idea is to have a boot loader on a DOS formatted floppy. 
This boot loader loads the kernel (kernel.bin) into memory,
and transfers execution to it.
  
The kernel is going to be primarily a scripting engine running in
ring zero, both user level scripts and binaries running as fast as
possible.
      
I have a boot loader and a basic kernel working. 

You can rawwrite floppy.img to a disk, and boot that, or
you can load floppy.img with an emulator. I use bochs for development.
     
The project is assembled using NASM, and compiled with gcc.
     
Currently working:
* Boot loader
* Protected mode
* A20 gate
* Interrupts
* Video driver
* Keyboard driver
* FLoppy driver (read only)
* Fat12 driver (read only)
* Memory manager
* Command shell
* Memory manager
* Directory browser
* Preemptive multitasking 

  It looks basically like a dos/unix hybird.

 Kernel files

Use rawwrite or dd to copy floppy.img to a floppy disk, and boot 
off of that.
