The two page PDF leaflet on Nikon\'s site lists the D100's lens compatibilities:
1) D-type/G-type AF Nikkor: All functions possible. 2) D-type Manual-Focus Nikkor: All functions except autofocus possible. 3) AF Nikkor other than D-type/G-type: All functions possible except 3D Matrix Metering. 4) AI-P Nikkor: All functions except 3D Matrix Metering and autofocus possible. 5) Non-CPU: Usable in M mode (camera's built-in exposure meter does not work). Electronic Rangefinder usable with lens with maximum aperture of f/5.6 or faster; IX-Nikkors cannot be used.
So you will be able to use your lenses, although it does look like the cameras meter will not operate.
