Chapter 6 Configuring System Firmware 123
To correct such problems, you must either manually change individual OpenBoot
configuration variables using the setenv command, or else type set-defaults to
permanently restore the default settings for all OpenBoot configuration variables.
Reference for Device Identifiers
Refer to the following table when manually specifying which devices to deconfigure
and reconfigure. The related procedures are covered in:
■ “How to Deconfigure a Device Manually” on page 116
■ “How to Reconfigure a Device Manually” on page 117
Note – The device identifiers above are not case-sensitive; you can type them as
uppercase or lowercase characters.
You can use wild cards within device identifiers to reconfigure a range of devices, as
shown in the following table.
