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 follow-
ing is displayed before control is passed to the image.
Boot
: disc(0/5/1/0.0;0)/stand/vmunix

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

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, all user input follows the ISL>
prompt on
the same line. Subsequent text is resultant messages from the ISL.
Default Boot
Entering
hpux initiates the default boot sequence. The boot path read from pdc is 0/5/1/0.0, the
manager associated with the device at that path is disc, and the object file name is /stand/vmunix.
ISL> hpux
Boot
: disc(0/5/1/0.0;0)/stand/vmunix
3288076 + 323584 + 405312 start 0x11f3e8
Booting Another Kernel Configuration
In this example, hpux initiates a boot operation for the saved kernel configuration myconfig.
ISL> hpux myconfig/vmunix
Boot
: disc(0/5/1/0.0;0)/stand/myconfig/vmunix
3288076 + 323584 + 405312 start 0x11f3e8
Booting From Another Disk
Only the hardware path and file name are specified in this example. All other values are boot defaults.
The object file comes from the file system on another disk.
