!		Bootstrap Help File - BOOT.HLP
!
!	This file describes the 4BSD UNIX bootstrap procedures.  
!	
!	In a normal reboot, the system checks the disks and comes up 
!	mult-user without intervention at the console.  Such a reboot can be 
!	stopped (after it prints the date) with a ^C (interrupt).  This
!	will leave the system in single-user mode with only the
!	console terminal active.
!
!	If booting from the console is necessary, the command
!
!		BOOT
!
!	will boot from the default device.  On an 11/780 the default
!	device is determined by a 'DEPOSIT' command stored on the
!	floppy in the file 'DEFBOO.CMD'.
!
!	There are other boot files on the floppy that allow booting
!	the system from other devices in multi- or single-user mode:
!
!	Command		Runs File	Action
!	----------------------------------------------------------------
!	BOOT 		DEFBOO.CMD	Boots multi-user from default device.
!	BOOT HPS	HPSBOO.CMD	Boots single-user from RP06, RP07,
!						RM03, RM05, RM80
!	BOOT HPM	HPMBOO.CMD	Boots multi-user from RP06, RP07,
!						RM03, RM05, RM80
!	BOOT HKS	HKSBOO.CMD	Boots single-user from RK07
!	BOOT HKM	HKMBOO.CMD	Boots multi-user from RK07
!	BOOT UPS	UPSBOO.CMD	Boots single-user from SMD-type disks
!	BOOT UPM	UPMBOO.CMD	Boots multi-user from SMD-type disks
!	BOOT ANY	ANYBOO.CMD	Interactive single-user boot (prompts
!						for boot device)
!
!	The choice of device and boot action is determined by parameters
!	loaded into general registers R10 and R11 at boot time, by the
!	boot command files.  The inputs to the BOOT program are:
!
!	R10  -  Device to boot from (0=HP, 2=UP, 3=HK)
!	R11  -  Action on boot (0=multi-user, 1=auto-reboot, 2=single-user,
!				3=prompt for device, single-user)
