OSDev demos

A collection of specific examples for x86 platform hardware or OS development concepts that I've written or adapted.

All examples are licensed under the MIT license, see LICENSE for details.

Requirements:

• i686-elf GCC/G++ and binutils (build/install instructions from OSDev Wiki)
  • The CMake file toolchain-i686-elf.cmake will expect to find this toolchain in ~/opt/cross/bin
• grub-mkrescue (with PC/BIOS binaries)
• CMake
• (for testing) qemu or other virtual machine
  • To install qemu on Debian-based systems, run apt install qemu-system-x86

Building any demo:

mkdir build
cd build
cmake ..
make livecd

The resulting live CD image will be in build/myos.iso

There is also a bash script that runs the above instructions for each demo and places the iso files into a directory named iso-files, with each iso file named after the subdirectory it came from.

Testing any demo:

Using qemu:

qemu-system-i386 -cdrom build/myos.iso
