Joe,
You are asking people who have a source license to violate that license. I
agree with you that the undocumented dump driver interface is a huge
annoyance, but Microsoft has to resolve this, we can’t help you other than
with vague generalities.
Microsoft, if you have a contact, generally is responsive to legitimate
requests for information on undocumented interfaces.

I’ve checked the book sources you list below. Nothing. Basically, If you
don’t have Windows source, your screwed. Yeah, Yeah, Yeah, you can always
try to hack your way through with brute force, symbols, and a debugger. But
I prefer to have a normal life.
Now, if someone could tell me what the second data structure in DriverEntry
is and what it is used for during a crash
dump/hibernation. I could then support hibernation and crash dumps in my
Virtual SCSI Port driver. Until then, hibernation and crash dumps are not
supported. Someone throw me bone.
PLEASE!
You Microsoft guys. Let the cat out of the bag here. Someone document this
interface. Is it really that important to hide?
