	Step	Description / Command
1	Start the emulator.	`# /opt/charon/bin/charon-par -f </path-to/configuration-file>`
2	Enter menu mode.	At the prompt Main Menu: Enter command or menu > type menu. This will display the available menu options.
3	Enter the configuration menu.	Type `CO` to enter the configuration menu. This will display the available configuration options.
4	Activate autoboot.	Type `auto boot on` to enable autoboot (or use the abbreviation `au bo on`). Autoboot is now enabled for the next boot.
5	Restart the emulator.	Stop the emulator: enter the exit command at thepa3>, pa9-64>,orpa9-32>prompt and hit Enter. Start the emulator again as shown in step 1.

...

	Step	Commands
1	Boot the system and log in as the Manager. Then copy the supplied autoboot file, and load the virtual tape file on LDev 7. LDev 7 is preconfigured in SYSGEN as device 0/0/1/0.6.0 (virtual tape MKA600 using container ldev7.img in the example). Wait for the message " `Vol (unlabelled) mounted on LDEV# 7` " to appear on the console, and continue.	`:HELLO MANAGER.SYS` `:COPY AUTOBOOT.CHARON, AUTOBOOT.PUB` `:DEVCTRL 7;LOAD=ONLINE`
2	Use sysgen to specify the new autoboot file and write the SLT. The line with the ? is a prompt asking for the tape number and a PIN. The PIN is represented in the sample here by the string XXX. Use the number shown in place of the XXX.	`:SYSGEN` `sysgen> sysfile` `sysfile> aauto autoboot.pub.sys type=disc` `sysfile> hold` `sysfile> exit` `sysgen> tape` `?19:00/#S2/XXX/ LDEV# FOR "SYSGTAPE" ON TAPE (NUM)?`
3	Respond to the prompt.	Press CTRL-A. This will display an `=` character. Type `REPLY XXX,7` after the = character replacing XXX with the number displayed in the prompt. Confirm with the Enter key.
4	Wait for the message "`boot tape is successfully built`" before you continue.
5	Exist sysgen, respond yes to the question if you really want to exit, and then shut down the system.	`sysgen> exit` (...) `Configuration changes are not kept yet!` `Still want to exit (yes/no) ? yes` `: shutdown system`
6	Stop and restart the emulator.	To stop, type exit at the Charon-PAR pa3> console prompt. Then restart the emulator.
7	Reboot the system from the virtual tape on LDev 7. Then update the system with the files from the virtual tape.	At the prompt `Main Menu: Enter command or menu`type boot alt (the default alternate boot path is LDev 7; if you change it, boot using the device path of the tape). At the prompt Interact with IPL (Y or N)? type Y. At the ISL prompt type `update config`.
8	The system will display the list of files that are updated. Wait for this to finish.
9	Boot normally. This should now be possible without interacting with IPL.	At the prompt Main Menu: Enter command or menu type `boot`. At the prompt `Interact with IPL (Y or N)?` type `N`.

Please note: After this step, the virtual tape container (ldev7.img in the example) can be removed or archived. It is no longer needed.

2	Enter menu mode.	At the prompt Main Menu: Enter command or menu > type menu. This will display the available menu options.
3	Enter the configuration menu.	Type `CO` to enter the configuration menu. This will display the available configuration options.
4	Activate autoboot.	Type `auto boot on` to enable autoboot (or use the abbreviation `au bo on`). Autoboot is now enabled for the next boot.
5	Restart the emulator.	Stop the emulator: enter the exit command at thepa3>prompt and hit Enter. Start the emulator again as shown in step 1.

...

To disable autoboot, follow the steps above, but use the command auto boot off instead.
