Routine Description:
This is the main routine that controls the loading of the NT operating
system on an ARC compliant system. It opens the system partition,
the boot partition, the console input device, and the console output
device. The NT operating system and all its DLLs are loaded and bound
together. Control is then transfered to the loaded system.
Arguments:
Argc - Supplies the number of arguments that were provided on the
command that invoked this program.
Argv - Supplies a pointer to a vector of pointers to null terminated
argument strings.
Envp - Supplies a pointer to a vector of pointers to null terminated
environment variables.
Return Value:
EBADF is returned if the specified OS image cannot be loaded.
