Use the BIOS setup utility to change configuration settings and to enable special functions. The cRIO-904x ships with configuration settings that work for most applications, but you can use the BIOS setup utility to change configuration settings to meet the needs of your application.
Changing BIOS settings can cause incorrect behavior, including failure to boot. In general, do not change a setting unless you are sure what the setting does. Reset the BIOS settings to restoring the default configuration settings.
