CPU serial number

Percon Posts: 5 Rating: (0)	Hi all, Can anybody tell me if it's possible to read the serial number of a CPU inside the user-programm, the CPU i want to use is a 318-DP? I know it was possible with S5 using the LIR instruction. This is possibly a controversial subject cause i want to use it to prevent my programm from running on different CPU's, (copy protection). Thanx Willy Maas
