What Is System Startup?
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 note 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 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 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 3000 MPE/iX Installation, Update, and Add-On
Manual (36123-90001). 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 900 Series
HP 3000: 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
and Chapter 3 .
