-/**
- * Memory mapped interface to the system console. This device
- * represents a shared data region between the OS Kernel and the
- * System Console Backdoor.
- *
- * The system console is a small standalone program that is initially
- * run when the system boots. It contains the necessary code to
- * access the boot disk, to read/write from the console, and to pass
- * boot parameters to the kernel.
- *
- * This version of the system console is very different from the one
- * that would be found in a real system. Many of the functions use
- * some sort of backdoor to get their job done. For example, reading
- * from the boot device on a real system would require a minimal
- * device driver to access the disk controller, but since we have a
- * simulator here, we are able to bypass the disk controller and
- * access the disk image directly. There are also some things like
- * reading the kernel off the disk image into memory that are normally
- * taken care of by the console that are now taken care of by the
- * simulator.
- *
- * These shortcuts are acceptable since the system console is
- * primarily used doing boot before the kernel has loaded its device
- * drivers.
