Why Windows XP does not install Video Driver 82845G/GL/GE/PE/GV Graphics Controller?

Hello!
I have observed many times during the installation of windows XP that it does not install video driver for Dell Optiplex Intel GX260 82845G/GL/GE/PE/GV Graphics Controller.
Whereas , Windows XP have a large number of Drivers. What is the reason of this? . Interesting thing that i did try to install this driver from Dell.Com but windows Xp did not configure with it.
regards,
Jack
