What does the "ROM backup" do in the temporary service mode?

I selected DSC>SD, and it asked me whether to "overwrite", and as i wasn't sure what i was doing, I selected no.

Does this put a copy of the current firmware onto the SD card?

I have a GH1 with firmware Ver 1.34 (the one that can't be hacked)
Would it be useful to have a copy of it for your work?

(PS I will be returning this camera soon!!!)
