Configure a Dynamic Setting

biosconfig cannot retrieve the strings and the mapping between the values in CMOS. This behavior is BIOS dependent; the ability to retrieve this information depends on the BIOS revision and the platform type.

To configure or export dynamic settings, you need to discover the setting that you wish to use by following these steps:

Enter the BIOS Setup utility.
Configure the settings manually and save the configuration.

To examine the resulting XML output to find the value that the BIOS is using for the setting you wish to specify, type:

# biosconfig -get_bios_settings filename.xml

This is an example of a dynamic CMOS setting as displayed in the XML file:

<BIOSCONFIG>
   <SETUP_CONFIG>
      <Boot>
      <Option_ROM_Enable>
      <NET0_Option_ROM_>
      <HELP_STRING>This Option enables execut....
      </HELP_STRING>
      <DEFAULT_OPTION> 0000 </DEFAULT_OPTION>
      <SELECTED_OPTION> 0000 </SELECTED_OPTION>
      <OPTION_RANGE> 0000 - 0001 </OPTION_RANGE>
      <OPTION-0>Not Available</OPTION-0>
      </NET0_Option_ROM_>
      </Option_ROM_Enable>
      </Boot>
   </SETUP_CONFIG>
</BIOSCONFIG>

In the preceding code, there are no string-to-value mappings offered by the biosconfig output.

To set the BIOS configuration, type:

# biosconfig -set_bios_settings filename.xml

Use this XML file to configure dynamic CMOS settings on machines of the same model.
