The 1.07.06 bootrom is included with 1.0 SP7 release and is typically in the "C:\LonWorks\iLon100\images" or "C:\Program Files (x86)\LonWorks\iLon100\images" directories. You will need to have the i.LON 600 software already installed on this PC before you can install this service pack (1.0 SP7). See the software readme for more information at the link below. Service Packs and updates are available at the "www.echelon.com -> Support -> Software Downloads". CD/DVD releases (1.0, or subsequent SR releases) are not available on the Software Downloads web site.
