I found this project on GitHub and it was dead quiet. After digging in, I think it deserves attention. Comments URL: https://news.ycombinator.com/item?id=48939596 Points: 3 # Comme…

The runtime commit above is the authority for boot.bin, kernel.bin, shell.bin, root.bfs, HELLO.BEX, SELFTEST.BEX, and ECHO.BEX. Documentation commits after it do not alter the verified runtime bytes. BONEBOX-01 is a native x86 real-mode operating system built from its own boot sector upward. It is not Linux with the visible parts removed. It is not a RAM-disk trick. It is not an ELF loader hiding behind firmware services. It boots through legacy BIOS, installs a resident nucleus, loads a transient shell from disk, reads a real filesystem, executes native external programs, and returns to a fresh shell by replacing the same 4 KiB arena. The point is not to pretend that fewer bytes automatically mean better software. The point is that every important byte has a named owner, a bound, and a verifier. Full setup, raw-image boot commands, ISO usage, and troubleshooting are in docs/USAGE.md. BEX1 is a fixed 16-byte executable header followed by a flat real-mode image. There is no relocation table, dynamic linker, import table, or resident process structure. SELFTEST.BEX proves segment setup, initial SP, BSS zeroing, writable BSS, and private stack use from inside a normally loaded external program. ECHO.BEX proves that bounded command-tail bytes survive shell replacement without entering the resident mutable block.
