NAME
      
setup - setup devices and file systems, mount root file system

SYNOPSIS
      
#include

      
_syscall0(int, setup);

      
int setup(void);

DESCRIPTION
      
setup is called once from within linux/init/main.c.  It calls initial-
      
ization functions for devices and file
systems  configured  into
the
      
kernel and then mounts the root file system.

      
No user process may call setup.
Any user process, even a process with
      
super-user permission, will receive EPERM.

RETURN VALUE
      
setup always returns -1 for a user process.

ERRORS
      
EPERM  Always, for a user process.

CONFORMING TO
      
This function is Linux specific, and should not be  used
in  programs
      
intended  to  be
portable,  or  indeed in any programs at all.  Since
      
Linux 2.1.121, no such function exists anymore.  The calling
sequence
      
varied: it has had a single parameter void * BIOS and at other times a
      
single parameter int magic.

Linux 1.2.9                       1996-05-03                         SETUP(2)
