Thanks for the details.I really have no idea, why you got a BSOD by using my method according post 1 of this thread and no BSOD by using the F6/floppy method. Is it possible, that you used different drivers from different packages? There are two nForce packages v. 6.69, one 32-bit for W2k3 and one 64-bit for XP and W2k3. Are you sure, that you took the 32-bit ones? No I used the 32 bit drive in either case. I once tried to use the 64 bit driver(by mistake) and it told me that they were not compatible.
