As mentioned earlier, the Initial System Loader (ISL) is run after the PDC. You would normally just run an "autoboot" sequence from ISL, however, there are a number of commands you could run from the ISL prompt.

Picking up where we left off in the preceding example, we have chosen to BOot off of 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> ?      HELP          Help Facility      LS            List ISL utilities      AUTOBOOT      Set or clear autoboot flag in stable storage      AUTOSEARCH    Set or clear autosearch flag in stable storage      PRIMPATH      Modify primary boot path in stable storage      ALTPATH       Modify alternate boot path in stable storage      CONSPATH      Modify system console path in stable storage      DISPLAY       Display boot and console paths in stable storage      LSAUTOFL      List contents of autoboot file      FASTSIZE      Sets or displays FASTSIZE      800SUPPORT    Boots the s800 Support Kernel from the boot device      700SUPPORT    Boot the s700 Support Kernel from the boot device      READNVM       Displays contents of one word of NVM      READSS        Displays contents of one word of stable storage      LSBATCH       List contents of batch file      BATCH         Execute commands in batch file      LSEST         List contents of EST (Extended Self Test) file      EST           Execute commands in EST (Extended Self Test) file  Enter 'LS' to see a list of the ISL utilities.  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 preceding 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:
