Support for 32 Bit Color Depth (32 bpp) by the Intel® 82810 and 82815 Graphics Controllers
32-bit color isn't supported by the Intel® 82810 and 82815 Graphics Controllers. As a result, a few games that require 32-bit color won't run on the Intel 82810 or 82815 Graphics Controllers.
32-bit color depth is only supported by the newer Intel® Graphics Controllers.
