Xu Yi wandered outside the computer room for a while and found that the computer room in the data bureau was really lively. After a while, there were more than a dozen people coming and going in and out, all of whom came and went in a hurry. Xu Yi was puzzled. After listening carefully outside for a long time, he understood that it turned out that the network in the bureau was disconnected, and they all came to find a technician named Xiao Lu to ask why.

Finally, when no one came back, Xu Yi walked in. Before he could walk a few steps, he heard Xiao Wang say, "Why are you here again? Didn't I say it will be fine soon? Dear brothers and sisters, I beg you to let me calm down so that I can get as soon as possible... Who are you? Go out quickly, you can't come in here casually." Xiao Wang looked up and found that the person coming was a little devil.

"Brother Wang, my dad asked me to ask..." Xu Yi panicked and directly called him Brother Wang to say that he knew the other party, and then he deliberately said only half of the words.

Sure enough, when Xiao Wang heard this, he showed a sad look on his face and waved his hand and said, "I know, the Internet will be fine soon." Xiao Wang's full name is Wang Bin, a fresh graduate who just graduated from university and is now internship here, so he can't figure out some of the relatives and the like in the game, and he doesn't want to figure it out. Naturally, he wouldn't know that Xu Yi lied to him.

After Wang Bin finished speaking, he didn't care about Xu Yi anymore. He lowered his head and tinked the computer in his hand, sweating profusely.

Xu Yi took this opportunity to start a large number of so-called computer rooms. In name, it was a computer room, but there were only three computers in it, which were Lenovo's brand computers. Xu Yi knew that since the end of 1993, Lenovo proposed the concept of creating a domestic computer brand and put forward the slogan of "carrying the banner of national computer industry". Until now, this slogan has basically been realized. The Chinese market is full of Lenovo's series, such as the "Tian" font series: Tianrui series, Tianqi series, Tianlin series, Scorpio series, etc., which almost occupy all the home desktop computer markets in China. Xu Yi could naturally predict that the government departments used Lenovo computers.

"well!"

Wang Bin's sigh aroused Xu Yi's curiosity. Xu Yi saw him lying dejectedly on the chair. Although there was an air conditioner in the computer room, he was still sweating profusely.

Xu Yi asked with a smile: "Brother Wang, why are you in trouble?"

Wang Bin was stunned: "Why haven't you left yet?" He was too devoted just now and didn't realize that the child has been here all the time.

"Haha, I'll take a look." Xu Yi came behind him and looked at the somewhat dazzling monitor. "I see you running around. Could it be that something went wrong with these three computers at the same time?"

"Isn't that?" Wang Bin was like a wicked wife at this moment. When Xu Yi asked this, he couldn't vomit any more depression. Another reason was that Xu Yi was a child. In Wang Bin's opinion, even if he told him clearly, he didn't understand. "The worst thing is that the hard drives of these three computers seem to be scrapped now. No matter what I use, I can't start it. Now the colleagues in the bureau are still waiting for me to connect to the Internet. Are you worried? That guy is really poisonous, didn't he just scold him, and he actually wanted me to lose my job..."

"Can't boot?" Xu Yi was quite strange. He had just seen Wang Bin use a floppy disk for a long time and thought he wanted to reinstall the system. Judging from the quality of these three computers, the hard disk should not be scrapped so quickly. Moreover, it would be too miserable to scrap three hard disks at the same time.

After hearing this, Xu Yi could tell the truth: "You said this is someone else's prank?"

"What kind of prank? It's obviously malicious destruction!" He was angry when he thought of this, but he regretted it very much. He was so quick to speak out and offended the master. As a result, he was chased here and instantly got three computers down. This is a public thing. If the supervisor knows that he not only has no work but also has to pay for it. Three hard drives will cost at least a few thousand yuan.

At this time, Wang Bin saw Xu Yi sitting in front of another computer and started to operate, and said casually: "It's useless. I've tried it. When entering DOS and Windows NT, it will crash. If you start the DOS system with a floppy disk, it will crash. When entering CMOS, select the hard disk type None and can boot it with a floppy disk, but it cannot recognize the hard disk. If you want to repartition and format it, you can't..." Wait! Wang Bin finally realized, why should I tell this to a child who doesn't know anything? Wang Bin felt it was a bit inexplicable.

"Hey, there's nothing to do with you here...Hi, hey, don't move around, it's not fun if you break it."

Xu Yi blinked at Wang Bin: "Haha, Brother Wang, don't think I don't know anything like other little kids, who should I scare?"

Wang Bin smiled embarrassedly: "Do you know computers?"

Xu Yi picked up a genuine Windows NT 3.5 disk and looked at it: "Of course, I also know that the hard disks of these computers are not scrapped..."

"Really?" Wang Bin's eyes lit up, and he was so happy that he was very happy, but then calmed down, "It's not good to speak loudly at a young age."

"Actually, this is just a trick to cheat. It has no technical content. As long as you understand the principles, you can easily handle it."

Wang Bin did not speak, but stared at Xu Yi. Xu Yi was not afraid that Wang Bin would not believe it. After all, whether he believed it or not would have any loss to him. If he had to lose it, it must be Wang Bin. What he wanted now was to be able to come here to surf the Internet frequently in the future. This is his real purpose.

"Okay, I believe in you. As long as you help me solve this problem, I will never refuse if I can help you in the future."

Xu Yi smiled: "No need to go back, let's start from today. I will help you repair your hard drive, and also help you solve the person who destroys your hard drive. The condition is that I can come here often to surf the Internet in the future."

"No problem, this is easy to deal with! As long as you can really help me, as long as I am still responsible for this in the future, the computer room will be allowed to enter and exit!" Anyway, I use public things, so I don't need to make a penny by myself. Wang Bin immediately agreed when he heard this. Now, as long as he can help recover the hard drive, he is grateful. As for dealing with the destructor, he doesn't believe Xu Yi has this ability at all.

"I forgot to introduce myself, my name is Wang Bin, what do you call my little brother?"

"Xu Yi."

"Xu Yi, what's going on? Judging from the current symptoms, it is clearly a characteristic of hard disk damage, and even formatting is not possible."

"Haha, Brother Wang, do you know the hard disk logic lock?"

"Hard disk logic lock? Never heard of it."

Xu Yi laughed in his heart, of course you didn't know, otherwise it would be really strange. You should know that this technology is only a handful of people in China now. This hard disk logic lock has a scary common name, called "hard disk bomb". After the hard disk is locked, the symptoms will be like this now. The system cannot guide it. If you don't know how to unlock it, it will be like it is scrapped.

This technology is truly known in July 1997. In 1997, five computer anti-virus manufacturers including Beijing Xinyuan, Beijing Ruixing, and Henan Jingwei held a joint press conference in Beijing, claiming that the latest version of anti-virus software launched by Beijing Jiangmin New Technology Co., Ltd. contains a "logical bomb", that is, under specific conditions, the software will damage the user's computer system, causing data loss and inability to guide - this is the famous "Jiangmin Bomb". Once the news was released, it immediately caused an uproar in the society. After the final identification, the computer security supervision department of the Beijing Municipal Public Security Bureau determined that Jiangmin Company violated my country's "Computer Information System Security Protection Regulations", which was intentionally inputting harmful data, endangering the security of the information system, and punished Jiangmin Company in accordance with the law.

The "Jiangmin Bomb" is a hard disk logic lock. If you accidentally run the program, the entire hard disk will be completely locked, and the program must be unlocked. This is Jiangmin Software Company's anti-pirated version measure, but it was finally used by its opponents, which severely smuggled the image of Jiangmin Company. However, the hard disk lock is indeed too vicious, which aroused public outrage.

After this incident, many people became interested in the "Jiangmin Bomb" and conducted special research on it. They found that its implementation principle is not complicated, but it cleverly utilized an incompleteness of the DOS operating system.

Xu Yi smiled and asked, "Is there any DOS below version 3.0?"

"After 3.0, I'll look for it." Wang Bin searched in the software package for a while, flipped out a floppy disk, looked at it, shook his head and said, "There is no one below 3.0, I only have one below 5.0. Who else can use one below 3.0? Do you want this to work?"

"It doesn't matter if it doesn't." Xu Yi did not answer his question. He could have used DOS version below 3.0 to start the machine. Although it does not support large hard disks, it doesn't matter. Xu Yi can directly use the assembly tool Debug, which comes with it, to modify the hard disk partition table, and then start it after modification.

"Is there any paper?" Xu Yi asked suddenly.

"Yes." Wang Bin handed over with paper and pen, "Give it."

Xu Yi picked up the pen, wrote it on the paper for about two minutes, then checked it again, handed it to Wang Bin and said, "Please take this program to another machine to compile it, then copy it to a boot disk, and then use it to guide these computers. It's OK."

Wang Bin looked at the code in his hand with confusion. This was written by Xu Yi in assembly, about one hundred lines. With Wang Bin's current level, he didn't see any reputation. However, Xu Yi wrote so many assembly codes at will, which shocked him. He also knew that the child, who was much younger than him, really understood computers and was even more powerful than himself.

"Okay, you can wait here for a while now, and I will go back."

Wang Bin went to a colleague with an assembly compiler to enter the program written by Xu Yi and then compiled it. He actually compiled it in one go!

With a deep sigh, Wang Bin copied the compiled program to the floppy disk and returned to the computer room.

"Xu Yi, you are so awesome. You have compiled it at one time!"

Xu Yi smiled and said, "Brother Wang, I happened to study this not long ago." Xu Yi wrote this program before, and it was not expected that his memory would be so good after he was reborn. Even in his previous life, he was not sure and wrote it by hand, without any mistakes.

Of course, Wang Bin knew that even if he had just edited it, ordinary people would not be able to write it meticulously. At least this proved that Xu Yi's memory was amazing. Now, he had completely believed Xu Yi's words, knew that his work could be kept, and he was in a good mood.

Use the boot disk containing that program to start the system, enter the "Modify" command, and then restart. The Windows NT interface finally appeared. Wang Bin breathed a sigh of relief. The other two computers followed suit and unbuttoned the hard disk logic lock in an instant, making Wang Bin smiled happily.

"It's done! Xu Yi, you have helped me a lot! If you want to surf the Internet in the future, come here." Wang Bin called Xiao Jiujiu. This child is so powerful. He learned more from him in the future. At this time, he thought of the one hundred lines of code, so he asked again, "Xu Yi, can you tell me the principle of this hard disk logic lock?" Wang Bin has also learned the compilation, so he can naturally understand it. The key is to understand the principle of the logic lock.

"Logic locks mainly deal with the partition table of the hard disk. You should know this, right?" Seeing Wang Bin nodding, Xu Yi continued to explain, "The partition table of the hard disk is located in the 0 cylinder 0 head 1 sector of the hard disk. The first 200 bytes of this sector are the main boot program, and the next byte is the partition table. The next byte can be subdivided. Each byte has its own specific meaning... The hard disk lock program is to rewrite the boot program of the 0 cylinder 0 head 1 sector, and destroy the partition table or deliberately create a circular partition table. When the DOS system starts, you have to read the partition table first. As long as the partition table is damaged, the hard disk will not be started. This is the principle of logical lock. Brother Wang, do you understand?"

"Uh... I understand a little bit." Wang Bin's face turned red. After all, he was a college student and could not be embarrassed in front of the child, but he only knew about the things the other party said, which hit him deeply.

"Haha, you can search through the relevant information on the principles of microcomputer and combine it with my program research."

When Wang Bin was in a daze, Xu Yi plugged the network cable that Wang Bin unplugged and dialed on the Internet. He felt excited. After rebirth, he finally surfed the Internet for the first time!

Originally, if the person who was sabotaging the destruction came again, Xu Yi planned to help Wang Bin teach him a lesson, but if the other party did not appear again, Xu Yi would be happy to save trouble. The person did not appear until a few days later, so he was naturally played with him once. Finally, he knew that there was a heaven outside the sky and never dared to be arrogant online from now on. Of course, this is a later story.

Xu Yi started wandering on the Internet. He asked Wang Bin what are the main websites in China now, and Wang Bin told him several websites.

Xu Yi has a rough understanding of the domestic Internet situation, the White House, the White House, and a BBS station abroad. It is extremely declining! After a while, Xu Yi said goodbye. Wang Bin kept reminding Xu Yi to come often, as if he was afraid that Xu Yi would never return.

When he returned to Xushan's office, Xu Yi saw that his father's face was full of sorrow, as if he was making something difficult to make. However, when he saw Xu Yi coming in, a smile appeared on his face. Xu Shan asked about his son's studies and then told Xu Yi to study hard and not to embarrass him, so he let Xu Yi go home.
