Changing the System Configuration

When you change the system configuration, for example, to add or remove an internal part such as a memory card or an external part such as a CD ROM or replace a PCMCIA card with one of a different type, you must halt the operating system and turn the power off. A configuration change requires you to reboot the system after adding or removing items. You will need to use the boot -r command to reconfigure the system.

Shutting the System Down

To halt the system, you must first become superuser.

1. Type su.

   ---

   tempest% su
   

   ---

   The system will ask you for a password.

2. Type your superuser password.

   A screen will appear with a # sign.

3. Type init 0.

   ---

   # init 0 
   screen messages
   ok

   ---

   After the ok prompt appears, you can turn the system off. Press Shift and the power key to turn the system off.

Rebooting After a Configuration Change

After you add a device to your SPARCstation Voyager, you must reboot in a particular way. After the system comes up, type boot -r to reconfigure the system.
