AeroOS

• OS made from scratch in Zig with EFI support.

Note

• The library I created in order to make this has been turned into an actual library, located here: https://codeberg.org/Land/zig-efi-lib

Usage

Downloading

1. Go to latest build action at https://codeberg.org/Land/AeroOS/actions.
2. Download the iso.zip artifact.
3. The ISO is contained in the downloaded zip.

Running with QEMU

1. Install QEMU/KVM and edk2-ovmf.
   • Arch Linux: pacman -S qemu-desktop edk2-ovmf.
2. SIZE=4G. Replace 4G with how much memory you want to give the Virtual Machine. 4GB is way more than enough.
3. qemu-system-x86_64 -bios /usr/share/ovmf/x64/OVMF.fd -cdrom AeroOS.iso -device virtio-rng-pci -m $SIZE.

Building

Native

1. Install deps
   • Arch Linux:
     • pacman -S make git mtools xorriso dosfstools cdrtools.
     • yay -S zigup-bin (or any other AUR manager)
     • zigup --path-link ~/.local/bin/zig 0.13.0
   • Debian: apt install make git mtools xorriso dosfstools.
     • Note: Zig must be installed manually (there is no debian package).
2. git clone https://codeberg.org/Land/AeroOS && cd AeroOS.
3. Building
   • Arch Linux: make all.
   • Debian: make all prog="xorriso -as mkisofs".
4. ISO is built to ./AeroOS.iso.
