Chen Fei thought for a while and said, "The book full of iron boxes was found by villagers in a dry riverbed by villagers, and this book was just one of them."

The all-stainless steel iron box is very sealed. I don’t know how many years it has been sunk in the riverbed, but the books inside are still intact and there is not even a trace of moisture.

Chen Fei took the book and after turning a few pages, he was attracted by the content inside.

"Huh? The a disk, b disk, and the drive letters are almost exactly the same. They are indeed very similar to this dos system, and they are also English commands."

This dos made him feel inexplicably terrified.

"It's getting more and more interesting. You can watch it slowly first, and I'll prepare lunch."

Seeing the books he collected was very likely to help Chen Fei, Teacher Chen Fei was also very happy, clapped his hands and pushed the door out.

Most students in this school bring their own lunches, and she doesn't need to worry about it. It's not troublesome to prepare more Chen Fei alone.

“These instructions…”

Chen Fei increasingly felt that the primary school teacher’s guess was probably right.

But how should these instructions be used?

For example, to eliminate the screen-filling subtitles, you should use the "cls" command. How should you enter it?

As soon as his thought arose, the lines of repeated subtitles in front of him suddenly jumped up, and new characters appeared again.

“…New hardware was discovered, driver was loaded, installed successfully, and can be used.”

“a:>\cls”

Oh, it's time to go up!!!

Chen Fei was stunned. He actually had voice input. So why did he not find the input/output device? Do you have to insert the keyboard and trackpad? This is also primitive enough.

When I saw the publication of this book, I saw the old antiques half a century ago, it was really enough.

But what should I do next?

Where is the Enter? Or the confirmation key.

Just as I thought of this, the repeated subtitles "illegal operation or wrong command" that occupied a considerable vision disappeared in the blink of an eye, leaving only a small character "a:>\_" left in the upper left corner, and the small horizontal bar at the end was flashing.

The whole world suddenly became clear without warning, as if it was quiet all of a sudden.

All the "sweeping subtitles" that troubled Chen Fei for a long time disappeared, just like returning to the initial time of "visual" symptoms.

Although there are still "a:>\_" that escapes the net, it is no longer a big deal and is even ignored.

It turns out that the "cls" directive is valid.

This made Chen Fei overjoyed. He grabbed the book "Introduction to Dos" in his hand tightly. Although the number of pages is not large, it is likely to be a good solution to "Visual".

However, the next second.

"Illegal operation or wrong command

Illegal operation or wrong instructions

Illegal operation or wrong instructions

Illegal operation or wrong instructions

…”

I started to jump down one after another.

The smile on Chen Fei's face suddenly stiffened.

Come again...

After only a few seconds of feeling better, the screen was flooded again.

(#￣￣￣#) Damn really wants to curse.

I gave the "cls" command and then thought about "Enter" in my mind. Maybe it was "confirm", but it was nothing anyway.

The operation made the same refreshed again and made Chen Fei feel relieved. This instruction is not a one-time, can be reused and very effective.

Even if the "illegal operation or wrong commands" that are still popping up, at least it gives him a way to clear his horizon at any time. He does not need to force himself to enter a state of selfless concentration, and relies on his subconscious to selectively ignore it.

He guessed that the "screen subtitles" he saw before were not static. Perhaps because each line is exactly the same character, it gives people the illusion of being still.

Of course, the ancient Dos system not only has the "cls" instructions, but also other operating instructions.

The book "Introduction to Dos" written by Chen Fei naturally records the introduction and usage of all instructions.

He tried again.

“a:>\b:”

"a" represents a drive letter, which may be either a physical drive or a storage partition.

Usually there is a b, there is b, there is c, and there is c... In a personal computer, there is often more than one physical memory and more than one storage partition, which does not include those hidden partitions.

Enter!

"Illegal operation or wrong command"

It seems that there is no B drive letter, and currently only one drive letter partition is troubled by Chen Fei.

According to the history of personal computer development, the a-drive letter and the b-drive letter were originally reserved for floppy drives. Now the floppy drive and floppy drive have long disappeared without a trace, leaving only a few samples displayed in the industry museum, and no one will use this ancient memory again.

However, according to tradition, disk a and disk b are retained by default by various subsequent systems. The storage partition often starts from disk c and automatically skips the initial a and b.

"b:" failed and an error message appeared, which means that there is no second partition except "a:>\".

So what exactly is inside this A-drive letter?

Chen Fei had no hope at all. Anyway, there were dates or no dates, so I would like to beat him first.

He found a command in "Introduction to Dos" to view the contents in the current directory, and "a:>\" happens to be the root directory, and perhaps you can also understand the capacity of this partition.

“di…”

Among the piles of "illegal operation or wrong instructions" prompts, Chen Fei had not had time to enter the complete text, but he heard Shen Fei's voice ringing outside the house.

"Chen Fei, the lunch is ready, and you will come out after washing your hands."

Lunch?!

Chen Fei lowered his head and looked at the health bracelet on his left wrist. It was already twelve o'clock local time. Time passed so quickly that he had read almost two hours of books without realizing it.

This is a brand new health bracelet. It turns out that the health bracelet that has been with Chen Fei for ten years is unknown in the battle with the golden dragon. He bought another latest model on the international medical ship, which is reimbursed by public expenses by the Apocalypse Defense Group.

This chapter is not over, please click on the next page to continue reading! Carefully put the "Introduction to Dos" that had been flipping for more than ten pages on the steel and wooden desk in the room, and then he responded loudly: "Come on, I'll be here soon!"

As soon as I pushed the door out, the fragrance of food came to my face.

Not far outside the door, a few plates of food, barbecue, vegetable soup, naan bread and small bread, and a few plates of side dishes were placed on an open-air rectangular table, which were simple and hearty.

There were also six little ghosts and Chen Fei sitting around the table, waiting for dinner together.

"Wow, it looks really good."

Chen Fei was a little surprised that this female teacher was able to create such a big table.

"Come here to sit!"

Chen Fei pointed to the empty space beside her and waved at Chen Fei.

After he sat down, he continued: "I have a freezer here, which has a large capacity and can store a lot of semi-finished products. There is also a large oven that can be roasted in everything. Try the pickled vegetables I made myself, dried radish, pickled vegetables, and stir-fried pickled vegetables."

"It's really amazing!"

Chen Fei gave a thumbs up without hesitation.

The students surrounding the table immediately praised their teachers, making Teacher Shen's cheeks flutter.

"Teacher Shen is the best."

"My mother's dishes are not as delicious as Teacher Shen."

"I can lick the plates clean, every time."

"I have never eaten such delicious dishes in my life. Teacher Shen, when I grow up, I will definitely marry you as my eldest wife."

"No, Teacher Shen is so beautiful, he must be my eldest wife."

"Bah, don't you see what you look like, bean sprout classmate!"

As they were talking, the two little kids were about to fight on the spot. These are all the words of "sweetness"!

The Patan children in the mountains mature early, are sensible early, and have strong folk customs. They all start to imagine the future like little adults.

"Stop, stop, stop, you guys, don't talk nonsense."

Chen Fei's tone became slightly heavier, and the children immediately became as honest as quails.

Chen Fei smiled and shook his head, saying, "I actually have a big wife. How many wives can you marry when you grow up?"

"Four!"

A big boy immediately raised his hand, then bent one finger, leaving only four vertical fingers.

The other children laughed and some of them shouted: "Muzke will get married next year. He is fifteen years old. His family has sent two sheep to the villages in the south and the villages in the west, and has booked two girls."

Someone added: "I know, I know that the girl in the southern village is named Emu, and she is the niece of my sister-in-law's house, and her face is like an apple."

There was another burst of laughter. The big boy who raised his hand was so happy that his face turned red, but he still stood straight, even a little proud and expectant.
