Kdfiles Not Working

[Dashonn Moulton]

OldDriver
Specifies the path and file name of the previous driver on the target computer. The syntax for OldDriver is the same as that of the first line after map in a driver replacement file. For more information about this syntax, see Mapping Driver Files.

NewDriver
Specifies the path and file name of the new driver. This driver can be on the host computer or at some other network location. The syntax for NewDriver is the same as that of the second line after map in a driver replacement file. For more information about this syntax, see Mapping Driver Files.

For more information about and examples of driver replacement and the replacement of other kernel-mode modules, a description of the format for driver replacement map files, and restrictions for using this feature, see Mapping Driver Files.

If you use the .kdfiles command without parameters, the debugger displays the path and name of the current driver replacement map file and the current set of replacement associations.

When you run this command, the specified MapFilefile is read. If the file is not found or if it does not contain text in the proper format, the debugger displays a message that states, "Unable to load file associations".

If the specified file is in the correct driver replacement map file format, the debugger loads the file's contents and uses them as the driver replacement map. This map remains until you exit the debugger, or until you issue another .kdfiles command.

To use user mode .kdfiles support, you need to first enable kernel symbol loading using the !gflag +ksl debugger command or configure the ksl global flags in the registry. For more information about gflag, see !gflag.

Be careful to appropriately qualify the .kdfiles paths for user mode .kdfiles. It is a bad idea to just match ntdll.dll (instead of system32\ntdll.dll) as otherwise the Wow64 NTDLL will get replaced with the native one. Similar situations can arise with other ambiguous substring matches.

After build 20172, the user mode .kdfiles mechanism will attempt to pull files from the debugger until one attempt fails; then, the file name that failed to be pulled will not be tried again for the boot session, without manual intervention from the debugger to modify the target system state. On earlier builds, the user mode .kdfiles mechanism will make one attempt (whether successful or not) to pull a given file name per boot session. These policies reduce the overhead of communicating with the debugger for files that are not in the kdfiles list, or that are inaccessible for replacement, such as due to sharing violations from processes that may have already loaded a given file. Because of this behavior, it is generally advisable to configure any files to pull in the .kdfiles list up front, before they would first be referenced.

Obtaining an initial break point is a necessary first step towards using .kdfiles for a boot driver, but
.kdfiles can fail to work for reasons completely unrelated to the initial break point. Ditto logging.

It would be really helpful to me if i get a solution to replace Nt kernel into debug version.
By Replacing Nt Kernel debug version i could collect detailed logs of NT kernel and make sure if windows kernel is getting BSOD due to mydrivrer.sys which is an BOOT_START_DRIVER.

In looking at the history of Windows driver development, there are some significant highpoints. Windows 2000, for example, introduced Driver Verifier which is the single greatest gift ever to be bestowed upon driver writers. This set the bar pretty high for what the next next Windows release, Windows XP, would bring. But I think we can all agree that XP really delivered. After all, it introduced three awesome features:

Developing drivers on Windows requires two machines: a host machine for development and a target machine for running the driver under test. We never, ever want to run our driver on our development machine for fear of corrupting our system from the incessant crashing of our buggy driver.

If at any point we want to clear the current set of mappings, we can use the /c switch to the .kdfiles command. Beware though that KDFiles overwrites the driver image on the target, so clearing the mapping does not actually revert the version of the driver.

We mentioned at the start that KDFiles is now even more useful, but how is that? Well, it turns out that the Boot Debugger also supports driver replacement. This means that you can automatically update your boot start drivers, which are otherwise a pain to update during development. To do this, you simply need to make sure that the boot debugger is enabled on your target machine using bcdedit:

Are you having problems opening a KD file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your KD files.

While we do not yet describe the KD file format and its common uses, we do know which programs are known to open these files, as we receive dozens of suggestions from users like yourself every day about specific file types and which programs they use to open them.

We are continually working on adding more file type descriptions to the site, so if you have information about KD files that you think will help others, please use the Update Info link below to submit it to us - we'd love to hear from you!

These apps are known to open certain types of KD files. Remember, different programs may use KD files for different purposes, so you may need to try out a few of them to be able to open your specific file.

Not sure exactly what type of file you are trying to open? Try our new File Analyzer. It is a free tool that can identify more than 11,000 different kinds of files - most likely yours too! It will help you find software that can handle your specific type of file. Download File Analyzer here.
