There are two types of CMOS settings: static and dynamic. The following dynamic settings are determined at runtime by the BIOS:
Value in CMOS
Behavior determined by that value
BIOS setup strings displayed
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 dynamic settings, you need to discover the setting that you wish to use by following these steps:
Enter the BIOS setup.
Configure this setting manually and save.
Run biosconfig-get_bios_settings and examine the resulting XML output to find the value that the BIOS is using for the setting you wish to specify.
This is an example of a dynamic CMOS setting:
<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 above code, there are no string-to-value mappings offered by the biosconfig output.
Use this setting with -set_bios_settings to configure other machines.
