The setup of the AT3IONT-I Deluxe was very easy, as you might imagine. There is really not much to setup. You drop in the RAM, HDD and DVD and you are off and running. After the installation of the OS (we used Windows 7 x64 Ultimate) the drivers and utilities installation was pretty much the same as any ASUS motherboard. You drop the DVD in and the auto-run goes off and gives you the install-all option.
As the AT3IONT is a MiniMax Entertainment system, it includes ASUS' Home Theater Gate software. This is much like the Windows Media Center.
There are multiple options that allow you to configure the way Home Theater Gate operates. There is one thing that you cannot do; for some reason the software will not let you map to a network share. You have to already have the drive mapped before the software will see it.
ASUS has also included a security software called ASUS VideoSecurity (big shocker). However, before you get excited about it, this will not link up to any IP cameras you may already have. At least we could not get it to do so. It seems that it will only work if you have the cameras attached directly to the system.
