Gabriel Majeri has created “biors”, a BIOS implementation written in Rust! It is only a few days old, does not appear to be ready for use yet.
biors – The Basic Input / Output Rust System
This repository contains an x86 platform firmware implementation – more commonly known as a BIOS. It is written in Rust, and is designed for modern x86_64 processors. Similarly to CoreBoot, it is designed to deliver a “payload” – this could be a PC-AT compatible BIOS, or a UEFI implementation. BIOS is pronounced “BY-oss”, this project is pronounced “BY-orss”.[…]

PS: Gabriel has also written C++ bindings for UEFI! 😉
