Why would you want to? DriverEntry gets called automatically when a
driver loads. It is allowed to assume that it is called only once in
the lifetime of the driver.

DriverEntry is assumed to be called once for a driver when it is loaded.
While technically you could call it, there are simpler and cleaner ways to
crash the operating system.

In the past the SCSI disk class driver did this to re-initialize the
SCSI bus after it detected a new device was available; with the advent
of PnP this isn’t necessary (or useful) any longer.
Driver Entry is nothing more (or less) than a function. If you want to
call it again, you can do so (although as Jamey points out, that assumes
it is still in memory and hasn’t been discarded.) Of course, like
anything unusual, it is your responsibility to ensure that you handle
the various conditions that might arise here correctly.

If you own both drivers, and you write the DriverEntry routines to allow
that, then the answer is an un-qualified yes. But if you call one of my
drivers, and your system crashes, my response to your trouble report will be
an unqualified “Don’t do that!”.

LOL! Thanks for the Monday afternoon chuckle
If you own the drivers, export DriverEntry and call it like a DLL. If you DON’T own the driver, then that is all the MORE reason NOT to call it.

Gary, and All others,
thanks of the responses you sent. Well, if I want to actually make the call, provided, I own both drivers, and also the DriverEntry code is not discarded using compiler settings, then is the call going to be something like
FooDeviceObject->DriverEntry(param1,Param2);
