Use and settings of hardware devices under DOS

With the popularization and application of computers, computer functions become more and more powerful and hardware devices become more and more powerful to meet people's needs, such as ISA, PCI sound card, modem, USB hard drive, mouse, and so on, and a variety of brands. So how should we use and set these devices in DOS? In fact, many hardware devices do not need to install any drivers in DOS.Program, As

Hardware project development experience

1. fully understand the design requirements of all parties and determine appropriate solutions To start a hardware development project, the original driving force will come from many aspects, such as the needs of the market, based on the needs of the entire system architecture, the functional implementation needs of the application software department, therefore, as a hardware system designer, we need to

Sharing the design of a distributed monitoring and remote control program for communication with hardware (medium: communication protocol design and implementation)

4. Roundtrip-based communication protocol design The core of the Communication Server plug-in is three parts: (1) Implementation of communication protocols unrelated to communication methods and business logic; (2) Implementation of communication business logic related to communication methods and business logic; (3) remote communication message queue. Here I will focus on the implementation of communication protocols. The implementation of this communication protocol is more agile. 4.1 basi

The use and setup of hardware devices under DOS _dos/bat

Because of the popularity and application of computer increasingly in-depth, in order to meet the needs of people, the computer's function with its development has become more and more powerful, more and more hardware equipment, such as from the original ISA and PCI sound card, modem wait for the current USB hard disk, mouse, etc., and brand a variety. So, how should we use and set these devices in DOS? In fact, there are many

Design and review of embedded system hardware principles

The following are some of my experiences and feelings based on my experience in circuit design and Debugging Over the past 10 years. Let's just call it "circuit schematic design review specifications, the excerpt is for your reference only.1) understand the design requirements in detail and clarify the functional modules and performance indicators of the circuit from the requirements.2) Formulate the overall design scheme based on the functional and performance requirements, and select the CPU.

Inux: Set system time and hardware time

Linux system time is sometimes not synchronized with hardware time Linux clock is divided into system clock and real time clock (RTC. The system clock is the current Linux kernel clock, and the hardware clock is the battery-powered clock on the motherboard. This hardware clock can be set in the BIOS. When Linux is started, the

With the rapid development of computer and IT technology, computer networks have become a very popular topic, which is closely related to almost every employee of the company) plan, set up, run, upgrade, and maintain, and publish and run to the enterprise website (including web, ftp, Email, and other services; from network security management to database management, storage management, network and personnel management, from network equipment to server and workstation (PC) operation management; f

Must the kernel interrupt number be the same as the hardware interrupt number?

First, the answer is no, the kernel interrupt number can be inconsistent with the hardware interrupt number, but this is a boring problem. Practical value is small. However, it can cause the consideration of the relationship between the kernel software interrupt number and the hardware interrupt number. the relationship between the two I think can be from the initialization and distribution of interrupts to

Dell server hardware information monitoring, automatic generation of server asset information

In the server hardware monitoring, the current industry is mainly based on the following two kinds: 1, the server comes with tools, such as HP's Hpacucli,dell OMSA, etc. 2. Intelligent Platform Management interface (IPMI, full name intelligent Platform Management Interface) Based on the above two kinds, through the Nagios, Zabbix or self-research operation and maintenance platform, such as the package, to carry out early warning operations. As the ser

Why can't the development speed of software keep pace with the development of hardware?

As the saying goes, "soft and hard does not separate", the smooth operation of the software requires good hardware platform support, and the performance of the hardware needs good software to reflect. Software is often used as a platform to design hardware, hardware, every development and upgrade is the platform jump-t

The application of hardware firewall in enterprise safety excavation

The most direct performance of network security threat to enterprise users is economic loss. Remove the direct loss of available money to calculate, due to security resulting in reduced efficiency, confidential information data leakage, system is not normal, repair systems and other indirect losses caused by the work can not be more worried, because this loss is often unable to use digital measurement. The result of this loss is that the network's enterprise security often encounters external in
