Basic (working, but older) IBM Thinkpad drivers are included in Windows XP by default, if I'm not mistaken. Therefor, they are NOT included in the DriverPacks (except for the Sound drivers). My guess is that you should NOT remove all drivers, and certainly not the ones that are labeled 'IBM Thinkpad' in nLite! EDIT: doh... Read it too fast... Hmmm............. nForce 4 chipset drivers must be the cause. Which versions of the DriverPacks BASE, DriverPack Chipset and DriverPack MassStorage are you using? EDIT: Oh yes, and which method did you use? Method 2, any chance?
