Deactivates the serial number of Pentium-III-CPUs
This simple utility deactivates the serial number of Pentium-III-CPUs from DOS - so it's no good for Windows NT/2000/XP users. The idea behind this straight forward approach is to turn the serial number off before other applications can read it. P3SN is especially useful if your BIOS doesn't support deactivation of the serial number. However it may be used in addition to other similar Software (i.e. BIOS or Intels related utility) to enhance safety.
P3SN is best loaded by placing a line like "C:\P3SN.EXE" at the beginning of your file AUTOEXEC.BAT. Note that P3SN requires Real-Mode to deactivate the serial number. That means it won't work if you have a memory manager like EMM386.EXE loaded (check your file CONFIG.SYS). It also won't work at the DOS-Prompt from Windows, which wouldn't be very useful anyway.
