Pyr0 is an attempt to make a python based Operating System, it means that we use language feature to provide security instead of using hardware as in a classical operating system.

The project is composed of two different parts: the core (which is a classical kernel that manages memory, interrupts...) and the runtime (which manages tasks, user programs...).

Another great idea of this project, is to have a plain-text userland. Indeed, there is no binary in the root tree (except kernel :P), only python scripts.

• qemu (for emulation)
• libisoburn (for video)
• perl (for some scripts required by compilation)
• gcc/make (for compiling)

• ./configure
• make

For interpreter mode:

• make boot-i

For file mode:

• make boot

or if you want a specific python's script:

• make boot PYR0_ROM=path_to_python_script.py

Example: make boot PYR0_ROM=root/python/prime.py

• math: very light math module (TODO)
• os: os information
• sh: shell builtins

• cpuinfo: cpu information
• smbios: various bios information
• pci: pci devices list

• mem: memory debug module

• morse: morse sound module (only on real hardware)

To try on real hardware (with usb key or cdrom), just dd the iso:

• dd bs=4M if=pyr0s.iso of=/dev/your_device

There are quite a lot of bugs, but of course, if you find a bug, please just open an issue.
