Attempting to implement a bare-metal OS, for the x86 processor architecture, from scratch. This project is just for fun, and so will not provide much (if any) value for folks looking for a more serious reference to OS design.
If you are looking for the most basic, hello world, type OS impelmentation then refer to the barebones folder.
[One time setup] make build-docker-image or docker build --platform linux/x86-64 -t moos . do this once to build a docker image. This image will be used to perform builds.
make docker or docker run --rm -v "$(pwd)":/moos --platform linux/x86-64 moos build a bootable iso with GRUB as the bootloader via docker. You can run the iso via a virtualization / emulation tool of your choice. Refer to the 'Makefile' for examples of virtual box and qemu.
A basic shell with the ability to execute some commands.
Just some window movement, doesn't offer any real functionality.
Some scripts / commands to help with the development workflow.
dd if=/dev/zero of=disk.img bs=256m count=2 create a disk 256MB (min for FAT 32) in size
mformat -F -i disk.img :: format disk with FAT32
mcopy -i disk.img example.txt :: copy text file into image
mdir -i disk.img :: list files in root
