Installing Video Drivers

I have a client with a Windows NT 4.0 workstation that I need to install the Video drivers. I had to re-install Windows NT last week and it overwrote the video drivers. The motherboard is an Asus CVU4X-V and and the drivers are on a CD that came with the motherboard. Its the VIA Integrated 4-in-1 driver set. When I go to display settings the color palette only shows 16 colors. I have installed these video drivers 4 different times and I cannot get more than 16 colors.

Any ideas on what I will have to do to get the drivers installed short of blowing away the C: drive and re-installing everything.

TIA for any suggestions.
