I've built an 8088 replica (Sergey's Xi 8088) and I'm having great fun with ELKS. https://github.com/jbruchon/elks https://github.com/jbruchon/elks ELKS is a Linux subset designed for the 8088, along with a complete toolchain (gcc-ia16). It's also actively maintained and comes with QEMU images and a dockerfile for fast, reproducible builds. Best to test it on live hardware, it's more rewarding and more fun a toy Unix than xv6. edit: typos
