It comes with commands for scanning for available video modes, unzipping gzip'ed files, and a kernel interface that allows it to call back into 16-bit real mode for BIOS calls, etc. Some debugging facilities are also provided, such as default trap handlers and the ability to set a hardware breakpoint. The initial console I/O can be redirected over a serial port for headless systems.
