Syntax (prefix with dash in a Generation Settings Scheme):

GenerateOnStartupEnabled=0 or 1

The GenerateOnStartupEnabled configuration parameter selects or clears the Generate on Startup check box on the ACS/TDK Settings dialog – 0 is cleared, 1 is selected.

You can use the FlagsSettingDisabled configuration parameter to make the Generate on Startup check box read-only after setting it through the GenerateOnStartupEnabled configuration parameter.
