xOS is a graphical operating system written for the PC entirely in assembly language. It aims to be modern and fully functional, yet be fast, small and simple.
- Graphical: Features a true-color compositing windowing system.
- Lightweight: Can boot using less than 32 MB of RAM, and the binaries are less than 1 MB.
- Networking: Features a functional TCP/IP stack.
- Self-hosting: Can assemble itself under itself.
- CPU: Practically any x86 CPU with SSE2 support.
- Storage: IDE and SATA hard disks.
- Graphics: VESA 2.0 or newer.
- Input: PS/2 and USB mice and keyboards.
- Networking: Realtek 8139 and Intel PRO/1000 cards.
- Others: PCI, ACPI, and other basic PC hardware.
- USB: Add support for USB 2.0 and 3.0, as well as USB mass storage devices.
- Networking: Rewrite the networking stack, and write/port drivers for more ethernet cards (Realtek 8169 and AMD PC-NET).
- Sound: Write drivers for common sound cards (AC97 and Intel HDA) and a basic WAV player. (Bonus task: add MP3 player too.)
- General applications: Write a text editor and a file manager.
xOS is provided as a disk image. disk.hdd in this repository is the latest unstable build. It can be used with QEMU or VirtualBox, but it performs best on VirtualBox. Stabler builds are in the Releases tab. For networking, use one of the Intel PRO/1000 options in VirtualBox settings. To run in QEMU, run make run. Instructions for running stabler builds are provided with their readme files.
