Hello everyone,
The Windows XP x64 video drivers for the Latitude D820, seem to be missing from the Drivers and Downloads page here: http://www.dell.com/support/drivers/us/en/04/Product/latitude-d820.
The video section is just not there for XP x64, however it seems like everything else is.
I know it's an old machine, but I still use mine, and Windows XP x64 will go well with my planned RAM upgrade. So if the drivers can be easily added from whatever database Dell has, that would be awesome.
