Protura
Protura is an OS Kernel and utilities, combining together to make a complete operating system. It is heavily inspired by the design of the Linux kernel and other various open source kernels and OS development information. Most of the existing parts of Protura are simplified versions of what is found in the Linux kernel, largely as a learning exercise.
Running the OS
The easiest way to run the OS is via the emulator QEMU. make debug can be used to startup a preconfigured debug environment in QEMU. It conveniently sets up TMUX with all the various commands already running, writes out to various logs, connecting up COM and IDE devices using the default compiled disk images.
In addition to QEMU, there is also VDI and VHD images which can be used to run Protura in VirtualBox or Hyper-V. For VirtualBox wire the VDI image up as an IDE drive in VirtualBox and choose a “Linux 2.4/2.6/3.0” machine upon creation (Though the choice here isn’t that important). You can then wire up extra devices like COM ports or a second IDE drive as wanted.
