I'm in the same boat here, but I have good news! It turns out that you can use the MicroMac Thunder/ThunderCache Control Panel and it'll work perfectly with the Extreme Systems Impact '030. Grab version 1.2.3 here: http://web.archive.org/web/20080618014213/http://www.micromac.com/software/software.html
