SystemZero GIF

A DOS-like operating system for the x86 CPU architecture. Has support for multiple IDE drives (IDE primary master is always the boot/system drive). Input is recieved from a PS/2 keyboard and output is given through 16-color 80x25 character VGA. A series of programs come with the operating system, they can also be loaded onto the virtual drive by the automake macro if you desire to run SystemZero inside a virtual machine.
