! 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) !
