From what I can see from the minimized JS, it: - Loads the linux binary and the root memory disk image into 'memory' at the expected addresses (0x100000 and 0x400000, respectively) - Sets the interpreted x86 CPU's EIP to the kernel's entry point - Initializes additional requisite register state - Starts execution. Take a look at load_binary() and start() functions. [edit] rickard already discussed this here: http://news.ycombinator.com/item?id=2555552 http://news.ycombinator.com/item?id=2555552
