The new challenge of the 486 computer to do the system

First of all, your computer configuration is so poor, it's best not to bother and buy a new one. A dual-core desktop is only 3,000 yuan. The 486 machine lacks a lot of features.

The 486 is an epoch-making processor produced by Intel in the early 90s of the last century, and is a milestone product of the modern high-performance processor family.

In 1989, Intel launched the 486 chip, which broke the limit of 1 million transistors and integrated 1.2 million transistors. The clock frequency is gradually increased from 25MHz to 33MHz, the 386 is integrated with the math coprocessor 387 and an 8KB cache in a single chip, and for the first time in the X86 series, RISC technology can be used to execute an instruction in a single clock cycle. It also uses a burst bus method, which greatly improves the speed of data exchange with memory.

As a result of these improvements, the 486 has a 4x better performance than the 387DX with the 386 math coprocessor.

486, like 386, has also appeared in several types one after another. The initial type presented above was the 486SX, which was a low** model in the 486 type, which differed from the 486DX in that it did not have a math coprocessor.

The 486DX2 uses clock frequency doubling technology, and its internal operation speed is twice the speed of the external bus, that is, the internal speed of the chip is twice the speed of the system clock, but it still communicates with the outside world at the original clock speed. The internal clock frequency of 486DX2 is mainly 40MHz, 50MHz, 66MHz, etc. The 486DX4 is also a chip with clock multiplier technology, which allows its internal units to run at 2x or 3x the speed of the external bus.

To support this increased internal operating frequency, its on-chip cache is extended to clock at 100MHz, which is 40% faster than the 80486DX2 at 66MHz.

You know? The market price of the tube radios produced in the fifties and sixties has exceeded 1,000 yuan, and the currency after the founding of the People's Republic of China has exceeded 10,000 yuan.

Keep it safe, this dusty old machine will bring you more than just a "broken" computer!

Your machine is likely to be an original Japanese machine! It is a very rare veteran PC. When we mention 486, we all can't help but recall memories of that wonderful childhood!!

We have enjoyed that good time without worries, without pain, only the happiness that 486 brings us. We will always remember! Goodbye – my 486!

This is a baby, don't mess with it.

I had to bake it on another computer. Take it again, and just pretend to be it. Hehe! 1. You can only install this machine like this.

Wouldn't it be better to install a DOS and play DOS games.

Create a file on the system disk, and write the program you want to run. is a text file. with edit. Carry it with you.

486 computer, you can install windows98, or linux, it's still good. How many years can still be used, it's not simple.

486 really recommends that you get a glass frame as a collectible. It doesn't mean anything else, you can get a set of Celeron for 50 yuan when you go to the thrift market.

The collection value of this machine is higher than the use value.

8M memory, 420M hard disk, installation, expansion to 16M memory can be installed Windows98

8M RAM, 420M HDD, installed, or DOS system.

In view of the above configuration. It is recommended to use win98 for Danxiaopao,It's more troublesome to install a driver。 WinMe and XP should have more than 256 RAM in basic configuration. Or install the inner mold to save to 256MB, the cost is about 100 yuan.

You can use the official original version of Windows 95 or the 98 system of Shixu 98.

In the late eighties and early nineties, the 486 processor was introduced, and roughly speaking, the 486 was the 386 that integrated a floating-point unit and 8KB cache (it is said to be high-speed, but there is also a considerable gap compared to the speed of today's general memory). The early 486 is divided into 486DX with coprocessor and 486SX without coprocessor, and its ** is also very different. With the continuous development of chip technology, the frequency of CPU is getting faster and faster, and the external equipment of PC is limited by the process and can withstand limited working frequencies, which hinders the further improvement of CPU frequency.

In this case, the CPU frequency doubling technology appeared, which allows the CPU to work internally at 2 3 times the frequency of the processor's external frequency, from which the name 486DX DX4 is derived.

In '97, we used 486 in elementary school, and although there were windows at that time, 486 was still very expensive and not popular.

Teachers don't understand it, the operation is very complicated, and there is no function.

It was also in those days that only the better schools in China could afford computers.

You talk about whether you can go online, and if the computer is not online, can he call it a computer?It's just that at that time, there were few computers, and everyone didn't use the Internet, but could the bank work without Internet access?The display is that you can access the Internet, but you need to add some equipment to go online, and these devices are not cheap.

Later, in 2000, Windows became popular. By that time, it was Windows 98. In fact, even if you could afford it at that time, few people would buy it.

It's just that around 2000, the school added this kind of curriculum, and everyone understood it a little, so gradually some people bought computers. That's when computers really started to become ubiquitous.

In my place, in 1996, 486 was popularized, of course, the popularity does not mean that every family has one, but that for China's national conditions, as long as you have money, you can buy it, and you don't need to find a relationship to find a channel. In 1997, the CPU of the Pentium MMX had reached 100MHz, and the computer teacher of our high school was still introducing it with great emotion that a Pentium MMX CPU was equal to his salary for a month. If the criterion for universal access is that everyone can afford it, then I estimate that 486 will get 98 years, and 586 will get 2001 to be considered truly popular.

Of course, this is the situation in my province, and it is not accurate.

The old machine,Win95 or 98 system installed are 07 years ago。

A model of the processor, as if it is now called Pentium, I think that at the beginning, it was also a kind of happiness to use 486.

The 486 is an old machine.

In elementary school, I used 486 and used the DOS operating system.

Click the "Start" button in the bottom left corner of your computer.

Then click "Run" to start running the program.

Enter "msconfig" and click OK.

After opening the "System Configuration" window, click "Start."

Uncheck the box in front of the items that do not need to be started at startup.

Click OK to restart your computer.

Click OK to restart your computer.
