how to add drivers and .reg to a winxp in a .gho file?

in some where i live we almost erveryone install xp from a .gho file, but there is a problem, how to integrate drivers or something else into a .gho file?
i am sure xp can’t use dism to integrate drivers, so there is any way to do it?

@xiaox

I suggest nlite

nlite only can handle a iso file, not a installed and run syspreped image
