I think the problem is on Winnt.sif....im doing this file with normal methods, i create with notepad, insert the lines and save like winnt.sif, just that.....is right ?? I just want to slipstream Sata drivers 10050 for my silicon 3112A, nothing more, what should i put obligatorily in the Winnt.sif ?? I can use this or its wrong for my purpose ?? I need to eliminate or add some line ??
