Conway's Game of Life in boot sector

Sep 21, 2026

Boot sectors are not only for loading operating systems.

They can be much more fun than that.

Over the weekend I built BootLife - Conway's Game of Life running directly from a 512-byte x86 boot sector, using VGA memory as the simulation grid.

Just BIOS, VGA memory, and a little bit of assembly.

Not everything we build has to be useful. Sometimes programming should just be fun 🪁
