Caution

Caution - Use extreme care when changing a configuration variable. An incorrect setting or typo can prevent the virtual machine from booting.

Note - Many variable changes do not affect the operation of the firmware until the next power cycle or reset, at which time the firmware uses the new value of the variable.

Access the OpenBoot CLI.
See Accessing the OpenBoot CLI and Getting Help.
At the OpenBoot prompt, type:
```
{0} ok set-defaults
```
