System startup refers to the procedure for starting the
computer software, namely the operating system, and other programs. System
startup does not refer to installing the system for the first time. (A separate
installation guide for your first loading of the new fundamental operating
software (FOS) comes with each FOS tape. See below.) Also, system startup does
not refer to turning on the power to the computer, disk drives, tape drives,
printers, or the system console. Normally, computer hardware remains powered on
continuously.
How System Startup is Carried Out
System startup involves several steps:
resetting the system placing system files on the system disk, if the files do not
already reside there starting the system using an autoboot or interactive
sequence
Starting procedures are administered and controlled through initial system
loader (ISL) utilities.
The initial system loader is software that provides a command-driven
user interface for accessing boot utilities or issuing commands
to display or change system startup functions. You can access ISL
by resetting the system. (Refer to Chapter 2 Initiating
System Activity for information on resetting the system.)
The START utility enables the system operator or system manager to
start (boot or initialize) the system after system files have been placed on
disk by the ISL INSTALL or UPDATE utilities, or after system
memory has been stored to tape or disk by the ISL DUMP utility.

NOTE: If you are installing the operating system for the first time, or
if you are updating your current system, please follow the instructions in the
HP e3000 MPE/iX System Software Maintenance Manual. This manual is
packaged with the FOS and system load tape (SLT) that you receive from
Hewlett-Packard.

There are two booting sequences available for the HP e3000 (Series 900):
autoboot and interactive. The autoboot sequence takes its utility commands from
an autoexecute file, also referred to as an autoboot file, and requires no
operator intervention to start the operating system. The interactive sequence
prompts the system manager or system operator for the utility commands and
options to start the operating system.
Autoboot and interactive sequences are discussed in detail in
Chapter 2 Initiating System Activity and
Chapter 3 System Startup Functions
