NAME
     newboot - load boot programs onto the hard disk boot  parti-
     tion

SYNOPSIS
     /usr/sbin/newboot    [-y]    /usr/lib/boot    /usr/lib/mboot
     boot_special

DESCRIPTION
     newboot copies the named  boot  programs  to  the  specified
     boot_special hard disk partition;  unless the current direc-
     tory is /usr/lib, you must specify full  pathnames  for  the
     boot  programs.   The boot_special section of a hard disk is
     typically the first 100, 512-byte blocks on the device,  and
     has  a  file  name  of the form /dev/rdsk/c?d?s7;  it can be
     identified using prtvtoc and looking for the partition  with
     the  tag  of  1  (BOOT)  and  size  of 100 blocks.  You must
     specify the raw (character) device name.  If the  -y  option
     is  not  specified, you are prompted for confirmation before
     the boot_special partition is overwritten.  The  mboot  pro-
     gram is the 512-byte micro-boot file loaded by the boot dev-
     ice firmware;  its main function is to load and execute  the
     larger  boot  program.  The boot program is the boot program
     for hard disks that loads and executes the bootable  operat-
     ing system (unix).

NOTES
     Installing bad boot programs  may  make  the  affected  disk
     unbootable.  Be sure you have a good backup copy of the disk
     before newboot is run.

DIAGNOSTICS
     newboot returns an error if the specified boot programs  are
     not  found.   Either change directory to /usr/lib or use the
     full  pathnames  of  the  programs  (i.e.,   /usr/lib/mboot,
     /usr/lib/boot).
