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"
