No, you cannot. Why in the world do you think you need this?

Yes, you can, but it doesn’t have to be honored.

See: link /BASE and ‘Choosing a Base Address’ in the WDK docs.

Good luck,

Not a problem.

I don’t think that a custom image base will have any effect on a driver as
they are always relocated.
The documentation confirms this:

I noticed that, but wasn’t quite sure what to make of it.

I mean, on one hand, it’s a pretty black and white statement, but on the other, there’s an awful lot going on there - DRIVERBASE, HALBASE and all the COFFBASE.TXT stuff - for it just to be cosmetic.

It seems like something there needs to be updated.

This field is ignored for drivers.

For the OP, why do you think that you need to do this? Drivers must not depend on hardcoded aspects of the address space layout.

Some of these things might have one day had meaning but do not necessarily anymore. Or they may apply only to early boot before the kernel is up and running.
