[fpc-pascal] Hardware

["Fabrício F. Kammer"]

Hi all,

How can I get hardware informations on windows/linux using 
FreePascal/Lazarus?

I need to get some informations of the hardware, like HD serial number, 
the amount of memory, the type of processor and another things.

I'm working in a software that I don't want that it runs in a different 
of the orginal installation then I'll save this informations in a 
crypted file and I'll read and check with the hardware in the moment of 
the software is open.

Thanks again
