Time flies! I have been registered for five years
The forum is less, I don't know because I can't access off and on these years, or fewer people using DOS
I wish the forum can continue to develop! At the same time, thank Roy for the space!

There are almost no people using DOS in China. Hey. Now even many high school students don't know what DOS is! (Except me, this high school student.)

I forgot when I registered, and it's a miracle that the website is still around

Stories of high school students.

Our network administrator upgraded the "whiteboard" computer with Windows 7 in the classroom to Windows 10, and the result was unanimously bad reviews (he forgot to install the supporting software). In desperation, he planned to downgrade. I joined in the fun during the upgrade, and I also joined in the fun during the downgrade.

I had investigated in advance that there was a factory image of the computer on drive D, backed up with GHOST. Then I joined in the fun, and there was a DOS version of GHOST and a batch file to start it. That's why we dared to upgrade Windows without backing up, but now seeing this image, we are worried.

Neither of us knows how to use GHOST. He has a WinPE boot disk, and we entered PE. PE has a Windows version of GHOST, but neither of us knows how to use it, and we are worrying about the English. Forget it, calling the batch file written by the manufacturer is the simplest way at the moment, without worrying about parameters or accidentally deleting data.

"Do you have DOS on your USB drive?"

"Of course!"

So, the "Command Prompt" was started.

Without saying a word, "Your computer cannot run this software, please consult your manufacturer."

"Hey, I'm not talking about this DOS!?"

"......I don't have that DOS on my USB drive......"

It's not really, at least there is a DOS version of DiskGenious, which can be started from WinPE.

After restarting.

"I'm keeping an eye on it, it's on drive E." (Note:)

"Don't worry......"

A:\>C:
C:\>DIR
No File Found.
C:\>D:
D:\>DIR
RESTORE.BAT xxxx-xx-xx xxxx
....
D:\>RESTORE.BAT

I don't remember which DOS drive the restore partition is on. However, other partitions on the computer are formatted with NTFS. Only the USB drive and the restore partition can be used by DOS.

Then, the familiar GHOST interface appeared. After all, I have seen it many times.

I was in a hurry to go home for dinner, so I went back first.

In the afternoon, I went to school, and the network administrator looked unhappy.

The manufacturer's restore image (it really is......) has home page hijacking software and a bunch of expired licenses. These are minor issues. He is much more familiar with Windows than I am.

However, what he can't accept the most is:

"When I installed Windows 10 back then, it took ten minutes, but this recovery took me half an hour."

However, if I had checked the information in advance, this bad idea wouldn't have been used. Now Windows' hard disk optimization is much better than DOS/BIOS.

Back then, I used DOS to crack the restore elf in the computer room (the BIOS was not locked, the boot order could be changed, bypassing Windows was a way, using DOS was much faster than other boot disks), but it was never implemented.

However, now that UEFI is prevalent, Windows 7 is difficult to boot, and DOS that heavily relies on BIOS may only be used to brag in emulators in the future. The BIOS in the classroom may be a customized version, because later I found out that there is a one-click recovery button on the white version (Android tablet + Win computer, Android part).

Boasting?

There is Magic DOSBox on mobile phones to run DOS programs. They can't brag because they don't recognize running DOS programs. Prepare an image, install Windows 95, and then they become very arrogant.

"How can your mobile phone run a computer?"

However, the simulation of DOSBox is only enough to support DOS games. For something as large as Windows 95 (it is said that there are problems like paging re - entry), it will crash every几十minutes.

But there are still many games in the DOS emulator that can be played, which is very good, but they can't be installed (they look down upon them).

Try to boot DOS from a USB drive on an old computer from 2017. Didn't try much, everything was okay.

Memory: HIMEMX crashed. XMGR was normal. 4GB of XMS (even if not fully recognized, it's a huge amount!). EMM386 and JEMM crashed.
Multimedia: Maybe only the one that calls Speaker can make sound. MPXPLAY recognized the HDA sound card but couldn't make sound.
Chinese characters: PDOS was the best to use, others either had garbled display or crashed (CCDOS).
Mouse: PS/2 compatibility in BIOS was there. The touchpad worked, but the connected mouse didn't.
(Originally was going to run Windows 3.2)
Windows 3.x couldn't run by default. Using HX DOS as a patch could enter standard mode, with memory -16K.

I have a laptop from 2013, and CCDOS doesn't have screen glitches.

Nowadays, computers all use EFI boot, and we can only solve it by virtualization.

Let me take a look

Now when logging in to the forum, I have to scan with WeChat every time, which is a bit troublesome. Even if I remember the Cookie, I still have to scan every time I log in.

I still have a laptop from 2008. I put DOS 5.0 in the USB drive (I didn't use DOS 7.1 because I didn't know about CDU at that time). CCDOS doesn't have screen flicker (even better than running it in VMware), and now I use it to brag. It really makes me miss the days when the computer could work well without UEFI.
