Wow – I hate downloading this stuff from HP. When I was done installing XP on a dc7800p most of the drivers were missing. And when I went to the HP site there were a lot of optional, superfluous downloads available. For instance, there were Nvidia graphics drivers (which didn’t work), at least five drivers for network/ethernet cards, etc. I have no idea how the hell you’re supposed to figure out what you need.
This download is almost 200 megabyte, but it is virtually all of the correct drivers…
