Changing classes

Hi,

I've a class that represents a general piece of hardware. Subclasses of that class represent more specific versions of that hardware. When I scan the network for hardware, I first only know some basic properties of the hardware and only after some more queries I'll know all details. I thought it would be a good thing to instantiate from the base class when I detect the hardware and then change the class to a more specific class as I find out more about the hardware.
But how do I change a class? I know about the ISA pointer, but changing it doesn't allocate any additional variables.
What would be a nice solution to this problem?

Kind regards,

Remco Poelstra
