 | 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...

LS produced two utilities available to us: ODE and HPUX. ODE is the Offline Diagnostics Environment.
