The author details 'nanokrnl', a functional Windows-like kernel written in Rust, and 'nanox', a custom 64-bit WebAssembly emulator designed to run it in a browser. Unlike existing solutions like v86 which fail with this specific kernel, nanox allows the OS to boot and reach a command prompt while occupying only about four megabytes of memory.
Background
Running complex operating systems in web browsers typically requires lightweight emulators or virtualization, often limited to 32-bit environments or simpler kernels due to performance and size constraints.
