Linux users do not know a bit about the manufacturing of open source hardware, they often fall into the mood of disappointment.Business software and freeware software have been entangled for many years, but these two often misunderstand each other. It's not surprising-it's business for one side, and the other is just a way of life. But this misunderstanding can be painful, and that is why it is worth the effort to expose the inside.An increasingly com

Abstract: In today's popular Windows operating system, device drivers are the lowest-level software interface for manipulating hardware. In order to share the experience in the process of device driver programming, 5 Methods of notification application of device driver are given, and the principle and implementation process of each method are described in detail, and some core code of implementation is given. Want to be able to provide some help to th
Software-bound Computer hardware identification is an anti-copy method used by many software. However, it is not a simple matter how to determine the unique identity of the computer hardware. The following are commonly used methods and their pros and cons.1 Method of computer uniqueness Identification 1.1 CPU serial number availabilityThe existing CPUs almost all support CPUID instructions. This instruction

This article will introduce the specific hardware fingerprint acquisition technology in detail and provide a demo source code program. Hardware fingerprint encryption means that after a user obtains and installs the software for free,
Part 8: bios and CMOS FAQs When it comes to bios, most cainiao don't know much about it and dare not try it easily, as if they are naturally afraid of the blue screen, even many old birds cannot distinguish BIOS settings from CMOS settings. Therefore, before writing a Q A question, I think it is necessary to clarify these two concepts to get twice the result with half the effort.BIOS is short for Basic Input/Output System. It is originally intended to be "Basic Input/Output System ". What we u
