Missing scroll lock on keyboard

Hello Forum,

I recently replaced the keyboard that came with my Dell Dimension 8200 with a Logitech Cordless Desktop EX 110 mouse and keyboard. I noticed that there isn't a scroll lock key on this keyboard which is needed whenever clearing the NVRAM on the Dim. 8200. I have checked Logitech website and can't find anything about this. Does anyone here know if there is away to configure this keyboard to use the scroll lock?   Thank you for your help..   Lee
