Kernel boot code
The kernel boot code
sets up tables
initialises hardware
starts an `init' process
cleans up after itself
Notes:
The kernel boot code does whatever
is necessary to set up its own data
areas and the devices and resources
it manages.
This normally involves setting up tables
in memory, putting hardware devices
into known states, and so on.
After this is complete, the kernel starts
an `init' process (on Unix) or a DOS
command.com, and cleans up any
remains of the boot process.
