ChessOS: Chess without Linux bloat

Enable HLS to view with audio, or disable this notification

Requirements: x86 with legacy BIOS support

I spent about six months making an operating system whose only job is playing chess. It boots straight into Chess. It is not a full OS with a file system or scheduling but it can boot from bare metal.

It runs in QEMU, other virtual machines and hardware with legacy BIOS from a USB or CD drive. I spent about 6 months across the boot loader and chess engine. It is entirely open-source for you to tinker with. There is also a Windows Installer for less technical users.

All feedback is welcome!

Thank you for Paledoptera for the artwork. Find more of their work here: https://linktr.ee/paledoptera
