First, thank you Inigo for your answer. I made as you suggest, unzip rxvt (I don't know any other way how to install rxvt) in my mape Program (I made it) on SD card where I have already both base-dr-v2 and FBReader-0.10.7-dr-vr4 but I always receive the answer 'The desktop app. cannot be opened.Possible the app. is already open. Close it first and try again' when I click on the icon 'FBReader.desktop or rxvt.desktop' in my SD card.
Next day after I received my DR800S, I downloaded firmware 2 if it is important for you to know.
