This will only work for 32 bit. Start by downloading the Intel GMA / Intel(R) 82915G/GV/910GL Express Chipset Family drivers for XP/2000 HERE. Unzip the drivers to a directory. Then Download and install THIS .INF updater utility (not intended for this use, but it helps us out).
After that, goto your Device Manager, Display Adapters, Whatever your display shows up as now (probably generic VGA), right click – Update Driver Software, Browse my computer, “Let me pick…”, “Have Disk…” then browse to the folder you unzipped the driver to, goto Graphics/ and select the igxp32 file. Press Open. Highlight Intel(R) 82915G/GV/910GL Express Chipset Family item in the Model list, press Next, then finish the driver install.
