Although all of the operations and options of
hpux can be used from isl interactively, they can also be
executed from an
autoexecute file. In the examples below, user input is the remainder of the line
after each ISL> prompt shown. The remainder of each example is text displayed by the system. Before
going over specific examples of the various options and operations of
hpux, here is an outline of the steps
taken in the automatic boot process. Although the hardware configuration and boot paths shown are for a
single server machine, the user interfaces are consistent across all models. When the system Reset but-
ton is depressed,
pdc executes self-test, and assuming the hardware tests pass,
pdc announces itself,
sends a BELL character to the controlling terminal, and gives the user 10 seconds to override the
auto-
boot sequence by entering any character. Text resembling the following is displayed on the console:
Processor Dependent Code (PDC) revision 1.2
Duplex Console IO Dependent Code (IODC) revision 3
Console path = 56.0.0.0.0.0.0 (dec)
38.0.0.0.0.0.0 (hex)
Primary boot path = 44.3.0.0.0.0.0 (dec)
2c.00000003.0.0.0.0.0 (hex)
Alternate boot path = 52.0.0.0.0.0.0 (dec)
34.0.0.0.0.0.0 (hex)
32 MB of memory configured and tested.
Autosearch for boot path enabled
To override, press any key within 10 seconds.
If no keyboard character is pressed within 10 seconds, pdc commences the autoboot sequence by load-
ing isl and transferring control to it. Because an autoboot sequence is occurring, isl merely
announces itself, finds and executes the autoexecute file which, on an HP-UX system, requests that
hpux be run with appropriate arguments. The following is displayed on the console.

ISL booting hpux
hpux then announces the operation it is performing, in this case boot, the devicefile from which the load
image comes, and the TEXT size, DATA size, BSS size, and start address of the load image. The following
is displayed before control is passed to the image.

Finally, the loaded image displays numerous configuration and status messages, then proceeds to init
run-level 2 for multiuser mode of operation.
isl must be brought up in interactive mode to use the operations and options of hpux. To do this, sim-
ply enter a character during the 10 second interval allowed by pdc. pdc then asks if the primary boot
path is acceptable. Answering yes (Y) is usually appropriate. pdc then loads isl and isl interactively
prompts for commands. The following lines show the boot prompt, the Y response, subsequent boot mes-
sages, and finally the Initial System Loader (ISL) prompt that are sent to the display terminal:
Boot from primary boot path (Y or N)?> y
Interact with IPL (Y or N)?> y
