What does motherboard burning mean? What is the function of the burn pins on the motherboard?

Motherboard programming refers to the programming of the motherboard's programmable chip, which is the BIOS chip, which is used to store the computer's basic input and output system.

It is the underlying system that the computer starts first, and can be updated by USB drive, DOS, Windows, or hardware programmer.

Motherboard programming refers to the program that can be integrated but cannot be washed.

The production process of electricity is extremely complex, with multiple processes such as power generation, transmission, distribution, and consumption. Among them, power generation refers to the place where electric energy is produced, such as: thermal power units, hydropower units, etc.; Transmission refers to the operation of using high-voltage lines to complete power transmission; Substation refers to the use of high-voltage substation to convert high-voltage voltage, ultra-high-voltage voltage and other electrical energy into low-voltage electrical energy; Distribution is the final step, which reduces the voltage and delivers the electricity to the consumer.

The power transmission and transformation project of the power system attaches importance to the two steps of transmission and transformation. With the rapid increase in China's electricity demand, there is an urgent need for power system transmission and transformation projects to undertake the transmission and transmission of the power system. A number of power transmission and transformation projects together constitute the main frame of China's power grid.

At this stage, China's power transmission and transformation projects generally have multiple voltage levels such as 110kv, 220kv, 330kv, 500kv, etc., of which 220kv is used more frequently in China; 330kV is commonly found in China's northwest power grid; The 500kV level is the highest, and the requirements for cost, capacity, and process are higher and more advanced. At present, China attaches great importance to the construction of 500kV power grid, which is the backbone of China's power grid. Power transmission and transformation engineering is an important engineering project in the construction of the main grid of the power grid, including transmission line engineering and substation engineering, which requires high costs, extremely complex engineering construction, and high construction technical requirements.

Power transmission and transformation projects generally include electrical installation, communication and automation, civil engineering, electrical equipment commissioning, system start-up and commissioning, etc. Among them, electrical installation includes the installation of primary equipment such as high-voltage equipment, and also includes the wiring and installation of secondary equipment such as protection and control systems; Communication and automation refers to communication engineering and substation automation; Civil engineering covers equipment foundation, building engineering, four-way and one-level, frame foundation, etc.; The commissioning of electrical equipment is to test and adjust the installed primary equipment and secondary equipment; System start-up and commissioning refers to the start-up and commissioning of the operation of transmission lines and substations after the construction of power transmission and transformation projects. The status quo of power system power transmission and transformation project management does not pay attention to the coordination of the project scheduleThe power system power transmission and transformation project is very different from other projects, and the requirements of the power system power transmission and transformation project are higher, and the construction progress is required to be carried out in strict accordance with the specified requirements to ensure that the project construction is completed on time.

At this stage, most of China's power enterprises do not pay attention to the management and coordination of the progress of power transmission and transformation projects, which seriously affects the quality of the project, which not only reduces the ability of construction personnel and engineers to control the progress of the project, but also has a great impact on the efficiency and quality of the project. A small number of power transmission and transformation projects only pay attention to the progress of the project, and lack the supervision of the project quality, resulting in the problem of urban power shortage.

It's said that it's a burning pin.,It must be used to connect the burning hardware to flash the program on the motherboard.。

I've never taken this brother seriously.

What is Burning Teaching? _?Flashcard?

I want to apply for a psychic amulet.

Flashcard is a kind of rewritable cassette for handheld game consoles such as GBA NDS, through burning, so that many games or various contents can be stored in a flashing chip, and then through the machine to read the content of the chip, use the content in the card. The flash chip used to store the game ROM, because the flash chip used to store the game ROM is used to run the program (game), and has high requirements for the speed of random storage, so almost all of Sun Bibi's flashcards use NOR-type flash as a memory chip, this chip has a relatively small capacity due to processing reasons, and the ** of the same capacity is also far higher than the NAND type flash chip used for the production of U disk class, which is also a programming system** The main reason for much higher than the USB flash drive. An important part of a flashcard:

The control chip is the core device that controls the card, archive memory, clock and other functions, and is also one of the symbols that can best reflect the technical content in the entire programming system. <>

Flashcards have a long history, dating back to before most GBA players were born, let alone playing NDS. The history of each brand of the flashcard is really complicated, and the workload of sorting out is relatively large, so I hope that someone will do it. I'll just briefly introduce the principles of each generation of flashcards.

First of all, all the way up to GBA, the cartridges of game consoles are memory. The memory is directly connected to the computer bus, and the CPU can be directly accessed, while the ordinary USB flash drive, SD, TF and other memory cards are equivalent to hard disks in principle. There are 2 types of memory, one is RAM, which can be read and written, and RAM is divided into two types, DRAM is ordinary computer memory, which needs to be refreshed constantly, and SRAM is static memory, which can always save data as long as it is powered on.

One is ROM, which can only be read but not written, and the content is burned in at one time when it leaves the factory. Of course, ROM is also rewritable, called can only be written once with a programmer, EPROM can be whitewashed with a programmer under ultraviolet light, and then re-written, EEPROM can be whitewashed with high voltage and then re-written, this is the thing on the computer motherboard BIOS (the BIOS of the game console and the computer are not the same thing). By the way, when it comes to the capacity of the cassette game console, it generally refers to the bit, while the CD game console and PC refer to the byte when it comes to the capacity, in other words, the capacity of the cartridge of the game console is divided by 8 to be the capacity we usually talk about.

But this is not absolute, sometimes there are some unprofessional references in the industry, such as the so-called "high K" strong card in the FC era, which refers to games above 128KB, which is equivalent to 1MB in the field of game consoles. However, the game card itself is already memory, so the game machine does not need to bring its own memory, most of the game machines with cassette, only a little bit of cache, when you need to read the data, the CPU can directly read the card with data output, which is essentially different from the computer must first read the memory from the hard disk and then transfer it to the CPU. But there is a flaw in this structure, which is that the capacity is limited by hardware.

As we all know, the number of bits of the CPU determines the addressing space, so like the 8-bit CPU of FC (6502C), the maximum memory it can access is 64K, which is too small, so various extended memory technologies came into being, further, since the cartridge itself is connected to the bus, then you can access other chips or even change to a new CPU, this is the mapper often mentioned by FC simulators, it is actually an emulator for specific external chips, different manufacturers have different external chips, It is a dream to think that Takuno wants to use a cartridge design to emulate all games. <>

"Flashcards" are not unique to the GBA era, there were similar products back in the FC era. But "flashcards" are definitely carried forward in the GBA era. For a while, all kinds of GBA flashcards flooded the market, and hundreds of schools of thought contended, so it was not lively.

And those powerful brands that are still working hard in the DS flashcard market today started in the GBA era. Next, I will introduce various mainstream flashcards from shallow to deep, and I hope to bring you help Chahui. What do you need to burn a game?

Answer: A computer is a must-have, and secondly, depending on the type of flashcard, the specific equipment is also different. Some flashcards contain two parts, flashcard cassette + burner (or flashing cable).

For example: EZ2, GBAlink, ELINK, G6, etc. Some flashcards are external SD flash memory cards, usually only one flashing Xiaoqing card after purchase, you also need to buy your own flash memory card, card reader.

For example, M3 series, SC series, EZ4. <>

Usually you need to add a new CPU

Or a graphics card. Or the supportiveness of memory.

improve compatibility and more.

You need to update the BIOS

Generally, notebooks that work stably are not recommended to be actively updated.
