REBOOT(8)							     REBOOT(8)

NAME
       reboot - UNIX bootstrapping procedures

SYNOPSIS
       reboot [ -d ] [ -n ] [ -q ] [ -s ]

DESCRIPTION
       UNIX  is	 started by placing it at the beginning of physical memory and
       transferring to the entry point.	 Since the system is not  reenterable,
       it  is  necessary to read it in from disk or tape each time it is to be
       bootstrapped.

       Rebooting a running system.  When a UNIX is running  and	 a  reboot  is
       desired,	 shutdown(8)  is  normally  used.   If there are no users then
       reboot can be used.  Reboot causes the disks to be  synced  and	allows
       the system to perform other shutdown activities such as resynchronizing
       hardware time-of-day clocks.  A multi-user reboot (as described	below)
       is  then initiated.  This causes a system to be booted and an automatic
       disk check to be performed.  If all this succeeds without incident, the
       system is then brought up for many users.

       Options to reboot are:

       -d     option  forces  a	 memory	 dump to the swap area (see crash(8v))
	      before rebooting.	 This can be used if the system is in a	 funny
	      state that you would like to ``snapshot'' and analyze later.

       -n     option avoids the sync.  It can be used if a disk or the proces‐
	      sor is on fire.

       -q     reboots quickly and ungracefully, without shutting down  running
	      processes first.

       -s     option reboots to single user mode.

       Reboot  normally	 logs the reboot using syslog(8) and places a shutdown
       record in the login accounting file (see utmp(5).   These  actions  are
       inhibited if the -n or -q options are present.

       Power fail and crash recovery.  Normally, the system will reboot itself
       at power-up or after crashes.  An automatic consistency	check  of  the
       file  systems will be performed, and unless this fails, the system will
       resume multi-user operations.

       Cold starts.  On an HP300, the boot procedure uses the boot rom to load
       a  boot	program	 from  an  LIF format directory at the beginning of an
       attached disk.  The /usr/mdec directory contains a  disk	 boot  program
       ``bootrd''  which  should  be  placed  in  a  new pack automatically by
       newfs(8) when the ``a'' partition file system on the pack is created.

       This boot program finds the corresponding  file	on  the	 given	device
       (vmunix	by  default), loads that file into memory, and starts the pro‐
       gram at the entry address specified in the program header.

       The boot program can be interrupted by typing `^C' (ctrl-C).  This will
       force  the  boot	 program to interactively prompt for a system to boot.
       If not interrupted, it will boot from the device from  which  the  boot
       program itself was loaded.

       The file specifications used for an interactive boot are of the form:

	      device(unit,minor)

       where  device is the type of the device to be searched, unit is 8 * the
       hpib number plus the unit number of the disk or tape, and minor is  the
       disk partition or tape file number.  Normal line editing characters can
       be used when typing the file specification.  Currently, ``rd''  is  the
       only valid device specifier.

       For  example,  to  boot	from the `a' file system of unit 0 on HP-IB 2,
       type “rd(16,0)vmunix” to the boot prompt.  For tapes, the minor	device
       number gives a file offset.

       In   an	emergency,  the	 bootstrap  methods  described	in  the	 paper
       ``Installing 4.3bsd on the HP300'' can be used to boot from a distribu‐
       tion tape.
