I don't know where it is in the manual, but somewhere there is an extended ISO mode or something like that.
You might not want to shoot at ISO 100, compared to ISO 200. According to some testing, you get decreased dynamic range at ISO 100.
According this analysis at dpreview:
* You get "only" 7.5 stops at ISO 100. (assuming that the D3 and D700 yield the same results and are set up the same way.)
* You get about 8.5 stops of DR from ISO 200 through ISO 1600.
