1) Do DriverPacks replace old/default drivers supplied with WinXP disk? If yes, is it possible to remove default drivers with nLite first and then add DriverPacks? If not, does it mean that DriverPacks install together with default drivers?

For the most part no... most drivers included with windows have not been updated since they were included . There are a few that are included because they were neccessary for certain reasons. Don't ever delete the included drivers with nLite or other method.

Graphics A is Gaming Graphics B is Business  (Quadro vs GeForce) C is the older drivers (Catchall) and are considered unlikely to ever be updated again / archive. Like Voodoo graphics drivers.

Why are there two "2)"s in your post???

Both will likely fail... .net needs to be installed before the ATI control panel... a reboot is a good idea too. .net idealy would be installed prior to GUI mode setup... IE in WinPE mode setup like from svcpack.inf . most all in one packs will not install from svcpack setup... some will... I install roguespears .net2 from WinPE for just that reason. I then install the rest of teh .net packages from GUI mode . You can do this many ways that are all correct... i offerd how i do it only as a single example of at least one way that does work. Everyone here likely does it differently except that we all install .net before we run the DriverPacks Finisher.

Welcome to DriverPacks. Excellent questions.

This is probably my first post here so don't blame me too much, ok?

I've read the basic tutorial on DP integration but didn't find an answer to a couple of questions:

1) Do DriverPacks replace old/default drivers supplied with WinXP disk? If yes, is it possible to remove default drivers with nLite first and then add DriverPacks? If not, does it mean that DriverPacks install together with default drivers?

2) How can I get more info on DriverPacks? I can see there are several Graphics (and Sound) driverpacks (A & B) and no matter which one I choose, I can see ATI and nVidia drivers inside both packs... Which one should I choose?

2) I use an all-in-one .NET installer merged using info found at MSFN forums. It contains all versions of dotnet up to 3.5 SP1 and installs through RunOnceEx (it's actually the first soft in the ROE list followed by other software). So, if I choose to install DP graphics pack for ATI or nVidia and want respective panels installed together with drivers, which method of integration should I choose - GuiRunOnce (winnt.sif) or ROE?

That's all for now! Thanks in advance, guys!!!
