Delphi-Quellcode:

////////////////////////////////////////////////////////////////////////////////
//
//  Simple VMware check on i386
//
//    Note: There are plenty ways to detect VMware. This short version bases
//    on the fact that VMware intercepts IN instructions to port 0x5658 with
//    an magic value of 0x564D5868 in EAX. However, this is *NOT* officially
//    documented (used by VMware tools to communicate with the host via VM).
//
//    Because this might change in future versions - you should look out for
//    additional checks (e.g. hardware device IDs, BIOS informations, etc.).
//    Newer VMware BIOS has valid SMBIOS informations (you might use my BIOS
//    Helper unit to dump the ROM-BIOS ([url]http://www.bendlins.de/nico/delphi[/url]).
