When a Charon-HPA instance is started, the first interface visible to the user is the PDC (processor dependent code) console of the emulated system (i.e., the firmware of the system). It provides some important function that will be described below:
PDC Main and Configuration Menus
At the console prompt Main menu: Enter command or menu > the user can enter either one of the available commands directly or display the main menu by entering menu:
Commands can be entered by typing the full command or the abbreviation indicated by the uppercase letters. The commands can be entered in lowercase or uppercase letters.
There is an overlap between menus, as shown by the configuration menu (type co or more letters of the command) below:
Important general commands that exist in both menus:
| Command | Description |

BOOT ALT | Boot from the alternative boot device. |
BOOT device | Boot from device with specified device path. Example device path: 0/0/1/0.0.0 |
PATH PRI | Display primary boot path. |
PATH ALT | Display alternative boot path. |
PATH <PRI | ALT> path | Set the boot path. If neither PRI nor ALT is specified, the primary path will be set. |

ODE MAPPER2 Program
The MAPPER2 program can be used to report all the emulated hardware of the emulated HP3000 or HP9000 system.
To start it, perform the following steps:
- Start the Charon instance.
- At the PDC menu, enter
BOOT PRIto boot from the main path. - At the prompt
Interact with IPL (Y or N)? >, enterY. - At the
ISL>prompt, enter the commandODE. - At the ODE> prompt, enter
RUN MAPPER2.
The program will display the hardware found on the system. A partial output is shown below:
After the program has completed, type exit at the ODE prompt to return to the ISL prompt, or type exit in the hppa console to stop the emulator.
