Jul 20, 2000  Delphi 5. How can I get an unique number for a specific PC, for example HDD Serial Number or Motherboard serial number?

At least, I've seen a product that claims to do it. Cannot remember it's name, but it was mentioned in a Spanish Delphi newsgroup, so a google search might find it. The HD serial is stored in some reserved part of the disk, and that program would know how to get to it. Manuel Algora ceni.@wanadoo.es.
