DeathOS

Boot loader written in assembly, checks for 64 bit support and then checks for long_mode

File/Folder navigation

  • src/impl/kernel/main.c This is the main kernel file, this gets ran after the boot loader
  • src/impl/x86_64/print.c This contains all of the printing functions, including printf
  • src/impl/x86_64/boot This folder contains all the files for when the os boots, including the 32 bit boot loader & 64 bit version, and the header

Setup

  • docker build buildenv -t deathos-buildenv

Load env

  • Linux/Mac: docker run --rm -v $pwd:/root/env deathos-buildenv
  • Windows cmd: docker run --rm -it -v %cd%:/root/env deathos-buildenv
  • Windows PS: docker run --rm -it -v "${pwd}:/root/env" deathos-buildenv

Build

  • make build-x86_64

Emulate

Personally, I use qemu, but you can feel free to use something easier such as Virtual Box

Real hardware/Barebones

This is a pretty basic thing still if you've ever installed an OS before.

  • Download rufus
  • Open rufus
  • For boot selection, select kernel.iso inside \dist\x86_64
  • Set partition scheme and select MBR
  • For target system, select BIOS (or UEFI-CSM)
  • Leave the rest as default, then just click START

Please note: Your CPU requires intergrated graphics since there is no graphics card driver
