That was just an example that any service you use you should ensure it comes up before your driver. In anycase, there are OS services which do come up before the disk driver, most likely very few and I haven't looked at the order of loading in a while. In anycase, the disk driver itself is on disk so how is it loaded if the disk driver isn't loaded? :) Most likely your driver comes up afterwards but it's just the point to ensure your driver is properly dependent on services it uses. 8bc7c0ec02c0e404c0cc0680f7018827ebee
