A DOS-like operating system written purely for demo purposes

WDOS

A batch operating system.

For the sake of demonstrating how to write a basic OS on x86.

Features

• a bootloader
• a kernel
  • a VGA console w/e keyboard functionalities

Building

Build disk image:

make

Run w/e QEMU:

make qemu

Run w/e Bochs

make bochs

To test WDOS on real computers, burn disk.img on a usb drive with the help of Win32DiskImager or dd, then instruct BIOS to boot from that usb drive.

Acknowledgements

WDOS is developped on QEMU, should run on most PCs with a legacy BIOS but not guaranteed.
I am not responsible for anything that happens to your computer.

Bootloader part is sparsely based on JOS, a predecessor of xv6, written by MIT educators to teach operating system.
