Booting

A

This appendix describes how to boot your system in different modes. Table A-1 lists the different boot procedures that are used to enter the different modes.

Table A-1

To Boot Up in this Mode	Do This	Result
Boot after connecting new 1 peripheral device	At the `ok` PROM prompt, type `boot -r` and press Return after shutting down the operating system, or after powering on the system, or interrupting the boot process, or when the open boot process has not been set for automatic boot.²	Adds the new device if you neglected to perform the `touch/reconfigure` command before shutting down the system when you added the peripheral device.³
Automatic boot	Power on system.	System automatically loads the operating environment, recognizes all connected devices, and boots to multi-user mode.⁴ ⁵

Table A-1

To Boot Up in this Mode	Do This	Result
Multi-user boot from the PROM prompt	At the `ok` PROM prompt, type `boot` and press Return.	Boots to multi-user mode.
Single-user boot from the PROM prompt	At the `ok` PROM prompt, type `boot -s` and press Return.	Boots to single-user mode. You are then prompted for the superuser password. Type the password and 6 press Return to enter single-user mode.

1. If you used the touch /reconfigure command before you shut down your system and peripheral devices, you do not need to use the boot -r command.

2. If the PROM prompt is >, type n to display the ok PROM prompt before you type boot.

3. The touch /reconfigure command performs the same function as the boot -r command. It allows the operating system to recognize the presence of peripheral devices.

4. If you do not turn on power to your peripheral devices before you turn on power to your system, the operating system has no access to those peripheral devices because it cannot recognize those devices.

5. The open boot PROM must be set for automatic boot.

6. To change the system to multi-user mode, press CTRL-d.

What's Next

To start the configuration process just after you boot your system, go to:

"Configuring the System" in Chapter 2, "Setting Up a Disk Drive" in this handbook to add a disk drive
"Configuring the System" in Chapter 3, "Setting Up a Tape Drive" in this handbook to add a tape drive
"Configuring the System" in Chapter 4, "Setting Up a CD-ROM or Floppy Disk Drive" in this handbook to add a CD-ROM drive
The on-line version of AnswerBook to configure the system for the addition of a board

If you are not configuring the operating system for the addition of a peripheral device, return to the hardware manual that referred you here.

Aborting a Booting Process

If you have to abort the booting process, you need to press a combination of key sequences, which varies with the system or monitor that you have.

Note - Use this procedure only in emergency situations. The system disks are not "synced" when the booting process is aborted.

* Press the combination of keys as described in the User's Guide or Operating System Guide that accompanies your system.

Usually one of the following combination of key sequences is applicable to your system:

Stop-a (for type 5 keyboards)
L1-a (for type 4 keyboards)
Break (for tty terminals only)

Pressing the combination of keys puts the system into the PROM (Programmable Read Only Memory) monitor mode. The monitor mode command prompt is then displayed on the screen. The prompt can be a "greater than" (>) symbol or the letters ok.
