Initial System Loader
Picking up where we left off in the previous example, we have chosen to BOot off device p0 and interact with IPL as shown in the following example:
Main Menu: Enter command or menu > bo p0 Interact with IPL (Y, N, or Cancel)?> y Booting... Boot IO Dependent Code (IODC) revision 1 HARD Booted. ISL Revision A.00.38 OCT 26, 1994 ISL> ?

 | Issuing a ? produces a list of ISL commands that we could issue. Issuing the DISPLAY command shows the boot and console paths and LS lists the ISL utilities available, as shown in the following example: |
ISL> display Fastsize value is 0000000F Autoboot is ON (enabled) Autosearch is ON (enabled) Primary boot path is 0/0/1/1.2.0.0.0.0.0 Primary boot path is (hex) 0/0/1/1.2.0.0.0.0.0 Alternate boot path is 0/0/2/0.2.0.0.0.0.0 Alternate boot path is (hex) 0/0/2/0.2.0.0.0.0.0 System console path is 0/0/4/0.0.0.0.0.0.0 System console path is (hex) 0/0/4/0.0.0.0.0.0.0 ISL> ls Utilities on this system are: filename type start size created ==================================================== ODE -12960 584 1216 00/01/21 16:45:48 HPUX -12928 3480 800 99/10/28 15:23:53 ISL>
DISPLAY produced the information we expected based on what we had seen in the previous section produced by PDC. LS produced two utilities available to us: ODE and HPUX. ODE is the Offline Diagnostics Environment. The following example shows listing the ODE utilities available on the system by running ODE, the HELP command, to see what commands are available, and LS to list the ODE utilities:

When we ran ODE in this example and issued LS the three utilities at the end of the example were listed. I always load ODE as a part of system installations to help in the event of a possible system hardware problem that an HP CE may need to diagnose.
Next we'll proceed with the boot process by running the HPUX utility:
