Debugging signed 64 bit drivers

How is kdfiles affected when debugging such beasts? Will .kdfiles load a
freshly built unsigned driver or must it be signed or, must the boot or test
signing be set in the target? I stgrongly suspect the later.

I would concur with the later.

If a debugger is attached then the driver does not need to be signed.
.kdfiles will load an unsigned driver. I do this all the time.

That's what I thought, and how it was working at one time. Well, it's been a
week of oh ****s, because ,kdfiles tain't working for me, on either signed
or unsigned drivers. Probably have something really stupid in my mapping
file.

Thanks for the confirmation guys.
