Driveimage Utilities is a pack of utilities that are to be used in connection with nkpatcher v8+:
* ISO image ripper / CD&DVD ripper
Insert a game disc into the drive and run the utility. There's no display output or sound or anything, but just wait. For example, ripping a 6.7 GB game will take about 40 minutes on my Xbox. After ripping, the utility returns to the dashboard and you should be able to see the game in your games list. The ISO image will be ripped to f:\games or g:\games depending on free space. These directories can be changed by editing backup.cfg. In addition to the .iso files, a default.xbe will also be created. This is the virtual disc attacher utility. The title name is automatically copied from the game d:\default.xbe. The same attacher file is included in the component directory of this package.
* Shadow C drive maker
This will create a one-to-one image of your current C drive to the file e:\shadowc\shadowc.img. Nkpatcher will automatically mount this image instead of the usual C drive. You can then install and update MS dashboard without modifications to the retail booting C drive. You should make sure that the shadow drive is actually mounted before deleting or modifying key files. To test, create a file, say test.bin, to the root of the supposed shadow drive. Then, using PBL, boot a bios without shadow drive support (there are no released bioses with this feature  ). Is the test file there? No? Good. Then reboot the Xbox so that you get nkpatcher version 8 patches. Is the file there now? Yes. Good. The shadow drive is working. Now you can let games update your MS dashboard as they please.
* Virtual disc attacher
This is the file automatically created by the ISO backup utility and is also contained in component\attach.xbe. When this xbe is run it will attach all files with .iso extension in the same directory in alphabetical order using an nkpatcher system call. In case there are several .iso files in the directory, these are assumed to be parts of the same big ISO file. Since Xbox FATX file system has a file size limitation of 4 GB, big ISO files need to be sliced into smaller parts. The ISO backup utility will do this automatically. After attachement, this program will quick reboot the system. If the attached ISO image contains a default.xbe in it's root directory, the kernel will execute it as is usual. Running the attacher on game ISO images will therefore launch the game.
* Virtual disc detacher
This will detach a previously attached set of sliced .iso files. If you for example do IGR (In-Game Reset) and get back to dashboard, the game disc will still be attached. You can browse it using e.g. boxplorer. You can run detacher to be able to use your DVD drive again. Of course, doing a full reboot will achieve this aswell (a dashboard option or nkpatcher with Full reboot -mode IGR.) None of these have any kind of a user interface; they work silently. So wait while the software does it's work.  Nkpatcher is included in the nkpatcher.zip file of this package. It is considered a separate program from this package. However, you should install it before using these utilities.
