This is not correct !!!

I am using WfW 3.11 on a Double Pentium Pro 200 with 1 GB of Ram

OK, Dos 6.22 and WFW 3.11 supports only one Processor.

But if I run Adobe Photoshop 4.0 on it, I have two Processors !!!

On loading APS ther ist a message 

        "Detecting Multiprocessorsystem..."

and if you have a single CPU board thats all... (it was my GA 586HX)

Now on my Intel PPro I get a following message 

        "Activating Multipocessor support"

Adobe can detect the second, third, fourth CPU and use it as 
additional Co-Processors...

But Do not ask me, what my PowerSuply tell me, if I start the APS. 
Normaly I have 180 Watt if APS is running I have 270 Watt

So, a guud programmer can detect the second,... CPU and can activate it.
But I think, it is possible wit ASM only not in C or anything else.
