xxxAxxx,
Its surprising what you can do by following the instructions given by other people who are more expert than me ! The ubuntu server works faultlessly, its on an uninteruuptable power supply, and I have a backup hotspare, if it fails.
I am running the latest SifTeam DGS image 13554 and installed (although I have no proof) uboot 1.3.3 using flashtools. I have an old Cuberevo Box as well however which is at my daughters house and it behaves differently to my more recent box even with the same image (even using a backup of the newer one) and my hunch is that it is using an old bootloader so I want to find out which version it is on before I update it.
