3. make install

If you get an error that the linker cannot be found, configure your linker in ~/.cargo/config.toml or something similar.

[target.x86_64-unknown-none]
linker = "/opt/homebrew/opt/llvm/bin/ld.lld"

run on qemu

1. Copy qemu's OVMF for x64 to var/ovmfx64.fd.
2. Follow the build instructions to finish the installation.
3. make run

run on real hardware

• Copy the files in the path mnt/efi created by the build to a USB memory stick and reboot your computer.
• You may need to change settings such as SecureBoot.
