Chapter 29-Effective Instructions
Shen Fei thought for a while and said: "The villagers from a nearby village found a tin box full of books in a dry river bed, and this is just one of them."< br>
The all-stainless steel iron box is extremely well sealed. It has been sunk in the river bed for who knows how many years, but the books inside are still intact, without even a trace of moisture.
Chen Fei took the book and after flipping through a few pages, he was attracted by the content inside.
“Huh? The drive letters of drive A and drive B are almost exactly the same. It really looks like this DOS system, and the instructions are in English.”
This DOS made him feel inexplicably confused.
"It's getting more and more interesting. You read slowly first, and I'll prepare lunch."
Seeing that the books in his collection are likely to help Chen Fei, Teacher Shen Fei also Very happy, he clapped his hands and pushed the door open.
Most students in this school bring their own lunches, so she does not need to worry about it. It is not troublesome to prepare more for Chen Fei.
"These instructions..."
Chen Fei felt more and more that the elementary school teacher's guess was probably right.
But how to use these instructions?
For example, to eliminate eye-catching subtitles, the "cls" command should be used. How should it be entered?
As soon as this thought came to his mind, the lines of repeated subtitles in front of him suddenly jumped up, and new characters appeared.
"... found new hardware, loaded the driver, installed successfully, and can be used."
"A:>\cls"
Ah, here we go! ! !
Chen Fei was stunned. It even had voice input. So why was there no input/output device found? Did he have to plug in the keyboard and trackpad? It's primitive enough.
Looking at the publication date of this book, wow, it’s an old antique from half a century ago. It’s really enough.
But what to do next?
Where is the carriage return? Or the OK button.
Just when I thought of this, the repeated subtitles "Illegal operation or wrong instruction" that occupied a lot of vision disappeared in the blink of an eye, leaving only a small section of characters "A:>\_" in the upper left corner, and the last The small horizontal bars flashed and flashed.
The whole world suddenly opened up without any warning, as if it had become quiet all of a sudden.
The "screen subtitles" that had troubled Chen Fei for a long time all disappeared, as if he had returned to the initial stage of his "visual hallucination" symptoms.
Although "A:>\_" still slips through the net, it is no longer a big deal and can even be ignored.
Turns out, the "cls" directive is valid.
This made Chen Fei overjoyed. He tightly grasped the "Introduction to DOS" in his hand. Although there were not many pages, it was likely to be a good solution to "Vision".
But the next second.
"Illegal operation or wrong instruction
Illegal operation or wrong instruction
Illegal operation or wrong instruction
Illegal operation or wrong instruction
……”
Lines began to jump down again before my eyes.
Chen Feixian The smile on his face suddenly froze there.
Come back...
A few seconds after I felt better, my screen refreshed again.
（#￣～￣#）I really want to curse.
I issued the "cls" command, and then thought "Enter" in my mind, maybe "OK", but it was fine anyway.
The same operation made his eyes clear again, and Chen Fei breathed a sigh of relief. This command was not a one-time use, it could be used repeatedly, and it was very effective.
Even if it cannot completely eliminate the "illegal operations or wrong instructions" that are still popping up, it at least gives him a way to clear his vision at any time, without forcing himself into a state of selfless concentration and relying on his subconscious to selectively ignore it.
He guessed that the "screen subtitles" he had seen before were not actually static. Perhaps it was because each line had exactly the same characters, which gave people the illusion of being stationary.
The ancient DOS system certainly not only had the "cls" instruction, but also had other operating instructions.
The "Introduction to DOS" in Chen Fei's hands naturally records the introduction and use of all instructions.
He tried the operation again.
"A:>\B:"
"A" represents the drive letter, which may be a physical drive or a storage partition.
Usually if there is A, there is B, if there is B there is C, if there is C there is D... In a personal computer, there is often more than one physical memory and more than one storage partition, and this does not include those Hidden partition.
Enter!
"Illegal operation or wrong instruction"
It seems that there is no B drive letter, and there is only one drive letter partition that is currently troubling Chen Fei.
According to the history of the development of personal computers, drive letters A and B were originally reserved drive letters for floppy disk drives. Now floppy drives and floppy disks have long since disappeared without a trace, leaving only the remains in the industry museum. There are several examples on display, and no one will ever use this ancient memory again.
However, according to tradition, disk A and disk B are retained by default in various subsequent systems. Storage partitions often start from disk C, automatically skipping the first A and B.
"B:" failed and an error message appeared, which means that except for "A:>\", there is no second partition.
So what exactly is in the A drive letter?
Chen Fei didn't have much hope at first. Anyway, there were dates but no dates, so he had to take a shot first.
He found a command in "Introduction to DOS" that allows him to view the contents of the current directory, and "A:>\" happens to be the root directory, and he may also be able to learn the capacity of this partition.
"di..."
Among a bunch of "illegal operations or wrong instructions" prompts, Chen Fei heard Shen Fei's voice ringing outside the house before he could complete the input.
"Chen Fei, lunch is ready. 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 12:00 noon local time. Time passed so quickly. He had read a book for almost two hours without even realizing it. .
This is a brand new health bracelet. It turned out that the health bracelet that had accompanied Chen Fei for ten years disappeared during the battle with the golden dragon. He was on the international medical ship again. I bought the latest model and it was reimbursed by Tianqi Defense Group at public expense.
Carefully placing the more than ten pages of "Introduction to DOS" on the steel-wood desk in the room, he responded loudly: "Here it comes, I'll be right away!"
< br>As soon as I opened the door and walked out, the aroma of food hit my face.
Not far from the door, there were several plates of food on an open-air rectangular table, including barbecue, vegetable soup, naan bread and buns, as well as several plates of side dishes, simple and rich.
There are six other little ghosts and Shen Fei sitting around the table, waiting to eat together.
"Wow, it looks really good."
Chen Fei was a little surprised that this female teacher was able to create such a large table.
“Come and sit here!”
Shen Fei pointed to the empty seat next to her and waved to Chen Fei.
After he sat down, he continued: "I have a freezer here with a large capacity that can store many semi-finished products. There is also a large oven that can bake anything. Try what I made. Pickled vegetables, dried radish, kimchi, and fried sauerkraut.”
“It’s really amazing!”
Chen Fei gave a thumbs up.
The students around the table immediately praised their teacher, making Teacher Shen's cheeks flush.
“Teacher Shen is the best.”
“None of the dishes my mother cooks are as delicious as Teacher Shen’s.”
“I can lick the plate clean, every time. ."
"I I have never tasted such delicious food in my life, Teacher Shen, when I grow up, I will definitely marry you as my eldest wife.”
“No, Teacher Shen is so beautiful, she must be my eldest wife.” Wife.”
"Bah, don't you look at what you look like, classmate Bean Sprout!"
As he said that, the two little brats were about to fight on the spot. These are all nonsense words. !
Patan children in the mountains mature early, become sensible early, and have strong folk customs. They are like little adults and start to imagine the future unscrupulously.
"Stop, stop, stop, you guys, don't talk nonsense."
Shen Fei's tone became slightly serious, and these children immediately became as honest as quails.
Chen Fei smiled and shook his head and said: "There is actually a big wife. How many wives can you marry when you grow up?"
"Four!"
A big boy immediately raised his hand The hand then bent another finger, leaving only four upright fingers.
The other children laughed and laughed, and one of them shouted: "Muzike will get married next year. He is already fifteen years old. His family has given two to the villages in the south and two to the villages in the west. Sheep, two girls have been selected.”
Someone added: “I know, I know, the girl from the southern village is called Amu, she is my sister-in-law’s niece, and she has an apple-like face.”
There was another burst of laughter, and the big boy who raised his hand laughed so much that his face turned red, but he still stood upright, even a little proud and expectant.

Single duty on Saturday and Sunday, washing clothes, cooking, spanking the children.
