Autobooting the System
Autobooting allows you to boot the system from the primary boot path without the need to make any keyboard entries. Boot messages vary slightly depending on whether autoboot is enabled. The following examples show some typical boot sequences and illustrate use of the material covered up to this point (resetting the system, system self- test, and using I/O paths). Autobooting a system is usually accomplished by enabling autoboot with the ISL AUTOBOOT command, resetting the system, and following the system's prompts. For information on the AUTOBOOT command, refer to Chapter 3 "System Startup Functions" Even when autoboot is disabled (or you have interrupted an enabled autoboot sequence as described in the next section), the system still allows you the option of autobooting by issuing an Interact with IPL (Y or N)?> message. (Bypassing a disabled autoboot flag setting to autoboot a system is discussed later in this chapter.) Example 2-3 demonstrates autobooting an N-Class system. The example is a partial listing of an uninterrupted autoboot (autoboot enabled) sequence. The screen may contain a different boot path display and additional information, depending on the system you are using. Example 2-3 Autobooting an N-Class System

If not, you get the message Cannot find an autoexecute file. AUTOBOOT ABORTED. For information on turning on autoboot, refer to Chapter 3 "System Startup Functions" For information on replacing autoboot files using SYSGEN, refer to Chapter 8 "Modifying System File Configurations"
Interrupting an Autobooting System
Even with the autoboot sequence in effect, you can override it to select an alternate boot medium (for example, a tape drive or another disk drive), to activate a different ISL utility, or to enter a different set of options. This is accomplished by pressing any key within 10 seconds after receiving the message that autoboot has been enabled. Example 2-4 provides a partial listing of an interrupted autoboot sequences for an N-Class system. Other systems may display different messages and boot paths.

When the sequence is interrupted, you are asked to select
whether the system should boot from the primary system disk or from
a system load tape on the alternate boot path. A third prompt allows
you to enter a different boot path interactively. As another option,
if you enter a "?" at the Enter boot path, command, or ?
prompt, you see a menu of boot command options.
The menu and boot command options can differ depending on
your system. Example 2-5 shows the menu for an N-Class System.

If you enter an improper boot path, forget to place the boot
device online, or if the disk or tape medium is defective, the system
displays a boot device status along with one or more four-character
boot error codes on the system console. Example 2-6 demonstrates
a system's possible response to an improper boot path.

An N-Class system was used in example 2-6. Other HP e3000
systems perform similarly, although their boot paths may be different
from the example shown. For an explanation of boot error codes,
refer to MPE/iX Error Message Manual Volumes I, II, and III.
The message Interact with IPL (Y or N)? gives you an additional chance
to autoboot even if you previously indicated an autoboot override (or have
autoboot disabled). Answering NO to the Interact message
returns the system to attempt an autoboot.
Interactively Booting the System with Autoboot Disabled
Interactively booting the system with autoboot disabled allows you to select a particular boot path or to activate ISL from the keyboard. The initial interactive sequence is similar to the initial autoboot sequence, except in the interactive sequence, the system does not prompt the user with the option to override the process. Example 2-7 demonstrates the interactive boot sequence for an N-Class system. The screen display may contain a different boot path and additional information, depending on the system you are using.

In this example, the system halts at ISL and then waits for the operator to
issue an ISL command. For more information on ISL and ISL utilities,
refer to Chapter 3 "System Startup Functions"
Bypassing the Disabled Autoboot Setting
Answering NO to the prompt Interact with IPL (Y or N)? causes the system to ignore a disabled autoboot flag setting and attempt to autoboot. Example 2-10 demonstrates bypassing a current disabled autoboot flag setting in order to autoboot. Example 2-8 Bypassing the Disabled Autoboot Setting When Booting a System
