This page is for a triple-boot live/install/rescue disk image for Alpine Linux, OpenBSD, and Plan9front. It uses a GRUB 2 BIOS bootloader and contains the installation media for PCs.

You can download it here from me: B703 577F D8C3 FD01 348B 1752 7D56 0CF3 E56A 32EB.

Once the image is decompressed and written to a USB flash drive of at least 2 GB size, it should boot to a screen something like this:

From this screen you can select any of the three OS's installation media.

This is an example in qemu but it should work on any supported PC type computer:

qemu-system-x86_64 -enable-kvm -drive if=virtio,file=boot.x86.img,format=raw

Selecting Alpine Linux should boot about exactly the same as the official Alpine "Extended" ISO:

Alpine is a simply made, minimal, secure distro meant for people already familiar with Linux.

Booting OpenBSD is similar:

I had to manually mount the disk with the image on it to access the file sets for installation. OpenBSD focuses on security research.

9front took a bit more finesse to boot in qemu:

Plan 9 is intended for systems research into extending the principles of the Unix Philosophy of software design.
