Sorry for delay.
Apologies though - I don't have a parameter list for unattended install. In fact such parameters have not been implemented in our current setup bootstrapper.
I've scheduled this request for a future update....we are looking at all sorts of improvements for installation, including discovery and push-install of nworks Collectors from our nworks Management Center.
If we can help you with any other aspects of deployment - let us know. Why do you have this requirement for unattended install?
