TetanOS

An attempt at building an operating system, make sure you're vaccinated.

Build dependencies

• mise — pins the Rust toolchain and runs the build tasks
• nasm
• GNU ld
• grub-mkrescue
• xorriso

mise install

Build

mise run build

The bootable image is written to obj/tetanos.iso.

Build from Docker

The docker image used is available here.

docker run --rm -v "$PWD":/build tetanos/builder

Run with qemu

qemu-system-x86_64 is required to run this command.

mise run qemu

Flash a usb drive

Be careful with this command, it will format your usb drive.

dd if=obj/tetanos.iso of=/dev/diskX && sync

Note for macOS dev

GNU ld doesn't produce the ELF kernel binary on macOS, so build from Docker instead.
