I have a Gateway E Series with a D865GLC motherboard. This is a "Made for Windows XP" box running windows xp home. None of the posted BIOS upgrades work, including the latest revision BF86510A.86A.0077.P25.EB.EXE . According to the instructions Windows users need to turn off their active desktop from the control panel before installing this upgrade. There is no way to turn off the active desktop from the control panel in XP. This feature first appeared with Vista. The active desktop must be turned off with Registry Modifications, something beyond most users.
