 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    [Toc]    [Back]

       setup always returns -1 for a user process.

ERRORS    [Toc]    [Back]

CONFORMING TO    [Toc]    [Back]

       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.
