Saw your other post...

The Froster is a Serial system. Not usb

So you'll have to buy an adapter if you have no Com port on the motherboard. The USB to COM serial adapter. Be warned, it doesn't always work.

But at least it's an option, and they're pretty cheap, though buy a decent one and you have a chance of the thing working.

I think 2.5 worked with most of the froster's, but I can't remember. Wish they were still around making/repairing them


Hope that helps
