Do you know what the two parameters for the status code mean?


The XP RK just says they are zero? How useful!

RK? Is this shorthand for Resource Kit? Where are you reading this, other than in the bug check code?



I was wondering why the address of the driver not loading is not
recorded?


I'd rather have the *name* of the driver which could not be loaded
but perhaps that would be too useful too! ; ]

That's my interpretion of what should be there. The form of Bug Check 0xC000021A differs from other Stop Errors. Most Stop Error reports are the format of a Bug Check code with four parameters. There have been a number of the Status code 0xc000026C reports with the zero parameters in Google. Bug Check 0xC000021A has similarities to Bug 0xC0000221 but the differences are something I have not yet studied.


That's why I suggested a safe mode boot, since I noticed that it shows
the names of modules as they are loaded. I thought that even if it
doesn't get loaded its name might show then and presumably it would
be the last name shown.

Where are you noting the loading of modules? A logged boot records these but it is my understanding that a logged boot is a normal mode boot. I am not aware of a way to log a safe mode boot. One Event Viewer report lists drivers not loading in safe mode but my suspicion is that it is an incomlete list. A list identifying which drivers load in normal mode, which do not in safe mode would help. Just as identifying those not loading during the but process but later on demand would also aid diagnosis.


Do you know anything about the OP's OEM system? E.g. does it provide
a Recovery Console which could be used as an alternate boot?
One of the suggestions then would be to try a driver rollback
(if a new driver had been installed by the "updates").

I have never played on a Dell computer. What I know is based on what I have read in Dell documentation and other user comment. One of the links I posted earlier leads to this link:
http://snurl.com/kfrun [support_dell_com]

Something in my memory suggests you may not be able to intall or run the recovery console but I could equally be wrong.

Also, surprisingly, the 0xC000021A supposedly occurs in User mode;
so diagnostics such as drwtsn32.log and user.dmp could be
produced.

Accessing the drwtsn32.log is something that has come into my thoughts recently but I have not yet explored the practicalities. I have tried viewing Event Viewer logs on a second computer. It does not work. There are other ways of accessing a computer that fails to boot other than the Recovery Console such as Linux disks.


I don't think those would help even if he had a Recovery Console
though.
He would need a full alternate boot to make use of such diagnostics.

Using the Recovery Console does require skills that not all seeking help can master,.
