"You need the right driver."
It is the one I provided a link to. I don't think it can be found by Service Tag number because Dell does not support XP on the A840; however if one checks out the "Compatibility" of the driver it is listed for 3 models including the A840.
"If you have the right driver there is no way you can't install it."
After working this board for years I can tell you that just having the correct driver does not ensure an installation.
