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 button 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
autoboot
sequence by entering any character. Text resembling the following is displayed on the console:

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.

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, simply
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 messages, and
