I was given an Omnipower Omni 1250 LAN battery backup system.  It looks rather old, but backup is backup...

My question...is it compatable with Windows 2000.  It has that screen that shows the status of the UPS system, and I want to know if this one will.

Also, anyone know the time this thing could run.  The battery in it is a lawnmower 12volt with 4 plugs on the back.
