Use this procedure to start your machine:
1. Skip to step 2 if you have a new system or your system is turned off. If the system is already turned on, do the following to put the backup tape in the tape drive and then shut down the system:
a. Log in as root user.
b. Put the backup tape in the drive.
c. Enter the following command:
shutdown -F
The Hal t completed ... message appears when the shutdown process completes.
Note: On some models, the shutdown command turns off the power to the system unit. It does not, however, automatically turn the power switch to the" Off position.
d. Turn the system unit power switch to the Off (0) position when the shutdown process completes.
2. Turn the system key (if present) to the Service position.
3. Turn on all attached external devices, such as terminals, CD-ROM drives, tape drives, monitors, and external disk drives. Do not turn the system unit on until step 6. Turning on the external devices first is necessary so that the system unit can identify them during the startup (boot) process.
4. If you have not already put the backup tape in the drive, do so now.
Notes:
• You may find that on specific hardware the tape drive door will not open while the system unit is turned off. If you have trouble opening the tape drive door during installation, use the following procedure:
a. Turn the system unit on.
b. Put the tape in the drive.
c. Turn the system unit off and wait 30 seconds.
• On some models that have a door to the tape drive, there may be a waiting period of up to three minutes before the tape drive door opens after you have pressed the button to open the tape drive. Some models also require that the button for the tape drive door be held in the pressed position for a few seconds
5. If you are not using an ASCII terminal, skip to step 6. If you are using an ASCII terminal, set the communications options as follows:
• Line Speed (baud rate)
=
9600Set the keyboard and display options as follows:
• Screen
=
normal display the Setup Menu and follow the on-screen instructions to set these options.If you are using some other ASCII terminal, refer to the appropriate documents for information about how to set these options. Some terminals have different option names and settings than those listed here.
6. Turn the system unit power switch from the Off (0) to the On ( I ) position. The system begins booting from the backup tape, which might move back and forth, or the CD-ROM.
Note: You can boot from production media (tape or CD-ROM) if your backup tape fails to boot. The initial Welcome screen includes an option to enter a maintenance mode in which you can continue the installation from your backup tape. Refer to
"Troubleshooting an Installation from a System Backup" on page 9-7 for more information.
After several minutes, c31 is displayed in the LED.
7. Choose the system console, if necessary.
If you have more than one console on your machine, each terminal and direct-attached display device may present a screen that instructs you to press a key to identify your system console. If these screens appear, press the specified key on the device you choose for your system console. (The system console is the keyboard and display device used for installation and system administration.) Press a key on only one console.
However, if the bosinst.data file lists a valid display device for the CONSOLE variable, you do not manually choose a system console. Read "Customizing the BOS Install Program" on page 4-1 for more information about the bosinst.data file.
S. The type of screen that appears next depends on whether you are attempting a prompted or nonprompted installation. Go to one of the following sections:
5-4
Installation Guide• "Nonprompted Installation" on page 5-5 if the backup image is configured to install automatically, without having to respond to the installation program.
OR
• "Prompted Installation" on page 5-6 if you need to use menu prompts to install the backup image. Use these instructions also if a nonprompted installation halts and the Welcome to Base Operating System Installation and Maintenance screen appears.
Nonprompted Installation
A successful nonprompted installation requires no further instructions because the installation is automatic. The sequence of events follows:
1. The first BOS installation screen appears on the monitor. This screen is untitled and blank, except for a zero digit in the bottom left corner.
The screen pauses for five to 10 seconds before the next screen appears. If you wish, you can use the short pause to interrupt the automatic installation and start a prompted session. Do this by typing three 000 (zeros) at the terminal. The installation will continue in a prompted mode.
Note: The nonprompted installation stops and prints the Welcome to Base Operating System Installation and Maintenance screen if the backup image holds configuration information incompatible with the machine you are installing. For example, if the image specifies a target disk that does not match what is in the machine, BOS installation starts a prompted session in which you can modify the installation.
2. The Installing Base Operating System screen appears next.

This second screen signals the start of the BOS installation, reporting the rate of completion and duration.
The Please turn the system key to the NORMAL position message appears on this screen if the key is not already in the Normal position. You can turn the key at any time while the screen is showing. The installation continues regardless of the
The reboot is automatic if the system key (if present) is in the Normal position.
Otherwise, another screen directs you, at the end of the installation, to turn the key to Normal and press Enter. The system reboots, in this case, when you press the Enter key.
