It is very easy to get the serial number of the main version in 9x, but this method does not work in NT/2 K. Okay, NT/2 K
The/device/physicalmemory device is provided to obtain the physical address. Under 9x
The serial number of the motherboard can be obtained through the access address fec71h. Although the serial number of the motherboard is not guaranteed for NT/2 K,
However, after repeated tests on multiple machines, the value of this address remains unchanged and unique. Below is my drive
TheCodeAnd I hope you can correct the error.
