//  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 (http://www.bendlins.de/nico/delphi).
