16 bits of precision?

Update:

After trying to update from the Intel Chipset to an ATI Radeon card, we still had the same issue--Windows was unaware of the the display hardware's status:

Highlights:

Card name: ATI Radeon HD 3400 Series
Manufacturer: ATI Technologies Inc.
Chip type: ATI Radeon Graphics Processor (0x95C5)
Display Memory: n/a
Video Accel:
DDraw Status: Not Available
D3D Status: Not Available
AGP Status: Not Available

It was clear that we would need Windows to know that DirectX was installed and
operating properly. We found a prior thread (also dealing with Optiplex systems) where a user describes a solution they found for this issue:

We followed to the instructions to change the registry key to "7" instead of "0" and after a reboot, the system recognized all the required DirectX components and DirectRT was able to start. Tomorrow, the lab will test the machines to see if their experiments can run now.
