Use the CPUID assembler command using Delphi's inline assembler. Here are a couple websites you might want to check out: http://www.clippings.vivitec.com.au/pp_article_id_7.html http://www.sandpile.org/ia32/cpuid.htm And don't forget to get a copy of the official IA-32 Developer Manual from Intel's website (developer.intel.com) that describes CPUID in excruciating detail. BTW, the CPUID's serial number command is disabled on most Intel-based computers. You can't rely on it to return anything but a bunch of zeros. (Most people asking for CPUID are after the serial # for integrating it with their software - typically disabled by the BIOS). -- Thomas Hruska CubicleSoft President Ph: 517-803-4197 Safe C++ Design Principles (First Edition) Learn how to write memory leak-free, secure, portable, and user-friendly software.
