China DOS Union

Since I need to use Fangzheng, I still have to use the old Windows 3.2. Recently, I saw that "New DOS Era" DOS 7.1 can support FAT32 and large hard drives and is compatible with Windows 3.2, so I installed both together. My C: is FAT32, 10G. But after I installed DOS 7.1, it worked, but Windows 3.2 didn't work. It seemed to say something about the file system being incorrect and too large. I checked and it seemed that Windows 3.2 can't use the FAT32 format. What's going on here? Isn't it said that with the support of DOS 7.1, Windows 3.2 can use FAT32 and large hard drives? Can an expert explain it?

Win3.2 can certainly support the FAT32 format under MS-DOS 7.1, and there's nothing much to say about that. Anyway, we've been using it normally for a long time. What prompt did you see? Please be specific if possible.

Thanks to the webmaster for answering in person. Tips? I need to copy them. I'll give it to you next time. However, this afternoon I installed WINDOWS 3.2 with DOS 622. It worked, but I can't see the drive letter of the CD-ROM. What did I not install correctly here?

Note: WINDOWS 3.2 and DOS 622 were downloaded from DOS Home.

There is also a small request: The installation process of DOS 7.1 has many options and installation windows. They are all in English. I can't understand them very well. I find the installation process quite difficult. Can you write a tutorial to explain it? I'm very grateful!

You said it can support FAT32. Is my C: drive partition too large???

Looking forward to your reply!!!!!

By the way, I downloaded the MSDOS71F compressed file. After extracting it, I used WINIMAGE6.0 to extract the two files DOS71＿1 and DOS71＿2 from it into a directory. But I didn't copy the three files DI, HD－COPY, and MAKEBOOT over there together. Will there be any problems? What are the files DI and MAKEBOOT? Looking forward to your reply!! Thanks!!

Did you use the copy method to install DOS 7.1? The di and other files are just the extracted files of the img image and have nothing to do with the complete DOS 7.1 system.. Please install DOS 7.1 using the complete DOS 7.1 installation CD.

His installation method does have some errors. Actually, the instruction files like README.TXT in the installation method all have introductions, and it should not be directly copied like above.

MS-DOS 7.10 supports very large hard disks and FAT32 partitions. For example, FAT32 partitions of 20GB, 200GB, etc. have no problems. Never use an old version of DOS on a large hard disk; otherwise, in addition to not supporting FAT32, it is very likely to damage the long filenames and file structures inside. There are also warnings on the download page of dos622 on "DOS Home".

Please post the prompt information to determine the reason. But normally there are no problems when using it. For more detailed information, please see:

I used the "Extract" command -> "Extract by pathname" in WINIMAGE 6.0 to extract the two files DOS71_1 and DOS71_2. I didn't use copying to extract the files inside. You guys, is the above method I mentioned correct? Please answer! Thanks

This is a feasible method, but it should be ensured that the system boots to a relatively pure DOS before you can enter SETUP to start the installation. The key is what is the prompt message when starting Win3.2?

I have two boot disks, WIN98 and DOS6.22, to boot the machine. Which one should I use to get to a relatively pure DOS?
Yesterday I also tried installing DOS7.1 and WIN3.2 in two formats, FAT16 and FAT32, on my old machine (1.2G hard disk, 16MB memory, don't laugh!). But none of them worked. Only DOS7.1 can be used and it works very well. But when I type the "WIN" command to start WIN3.2: the startup screen of WIN3.2 appears, then it turns black. Pressing any key doesn't work. But when I installed with DOS6.22 and WIN3.2, it was okay.
DOS7.1 is good. The key is that it can support FAT32 and large hard disks. That's what I most want. There's nothing to say about using it alone. But as soon as I install WIN3.2, it doesn't work. Does it mean that when I use WIN3.2, I must go back to DOS6.22?
Oh my DOS7.1!!!!!
Help me!!!!!!!!!!!!

To get a truly pure DOS, why not use the most correct installation method, which is to write DOS71_1 and DOS71_2 to a floppy disk, and then boot directly with the first disk to install directly? That is, the first installation disk itself is a DOS boot disk + installation program, not using another boot disk to boot. The method you used above is "feasible" but not the best method.

Regarding the problem of booting Win3.2, I find it very strange. Is there some wrong choice of options during your installation or other similar reasons? Try to modify the CONFIG.SYS and AUTOEXEC.BAT files (for example, see if EMM386 is loaded, etc.). We have always had no problem booting and running Win3.2 under MS-DOS 7.10, so it should be that your installation method is wrong or other similar reasons, not that it itself has a problem.

Thanks to the webmaster for answering patiently!

Just now I used the method the webmaster told to write to the floppy disk and installed DOS 7.1. After installation, I then installed WIN 3.2. After installation, restart.

Typing "WIN" command under C:\. It doesn't work! The prompt is as follows:

ERROR: pageovercommit value in SYSTEM.INI is too large.
Decrease the value, or if not present, add a setting that is less than 4.

Note: When I installed DOS 7.1, I didn't change the options. Just pressed Enter all the way. That is, when selecting the installation mode. Removed "install add-ons"

When installing WIN 3.2, when installing the printer, pressed Cancel. When installing the search application (said the installer needs to know the name of the application and asked me to choose), there are two options, one is MS-DOS EDIT and neither of the above. I didn't know, so I chose neither of the above. After installation, the above prompt appeared >

Webmaster, what is the reason for this? Where did I make a mistake. How to solve it? Thanks!

"ERROR：pageovercommit value in SYSTEM.INI is too large.
Decrease the value, or if not present, add a setting that is less than 4."

Finally, the real error message is given, and then everything becomes very easy.

I once wrote an article introducing the cause and solution of this problem. It was written in English, and the address is: http://newdos.yginfo.net/msdos71/doskbd4.htm

Now I will explain it in Chinese. This error message will only appear when the memory in the system is larger than 256MB. It is because the default settings of Win3.x are not good at supporting large memory. The solution is very simple. You can modify the default settings of Win3.x. Specifically:

In SYSTEM.INI, under the section, add a line PageOverCommit=x, where the product of the value of x and your physical memory size should not be greater than 1024MB. For example, if you have 512MB memory, then you can set x to 2 or 1 or 0, such as:


...
PageOverCommit=2
...

At this time, 512MB * 2 = 1024MB, which does not exceed 1024MB, so it should be okay.

The reason why this message appears when running Win3.2 under dos710 instead of under dos622 is that MS-DOS 7.10 fully supports large memory. That is to say, all the physical memory of the system will be recognized by dos710 and win3.2 at this time, no matter how large it is! However, dos622 supports a maximum of 64MB memory. So even if the physical memory of the system is far larger than 256MB, dos622 and win3.2 can only see up to 64MB memory at most, so this message will not appear (but if you set the x value very large, such as 20, so that the value of 64MB * 20 exceeds 1024MB, this message will also appear). It can be seen that supporting large memory is also a new function of MS-DOS 7.10, just like fully supporting FAT32 and large hard drives. If this message appears when Win3.x starts, it is not your mistake (of course, the previous installation method was wrong), but because Win3.2 itself is relatively old, and its default settings are not good at supporting large memory above 256MB. So you can adjust its default settings.

Thank you very much, webmaster! My problem has been solved. I can install DOS 7.1 and Windows 3.2 under FAT32. That's great. Why didn't I find this DOS 7.1 earlier? Its functions are much stronger than those of 6.22. Thanks! Here's a small question? Some places say "WINDOWS 3.11". Is this the same version as Windows 3.2 or different versions? Can you explain it? Once again, thank you! I will pay attention to this site. I can learn a lot here!

Win3.11 and Win3.2 are certainly not the same version. Win3.11 is only available in English, while Win3.2 is only available in Chinese. The Chinese version of Win3.2 is based on the English version of Win3.1 (not Win3.11).

I really don't know why there is win3.11. Its default boot sound is the same as wfw3.11, and the others are irrelevant.
And the boot logo is also 3.1. Only when you look in the program manager is it 3.11.
The boot sound of win3.2 is the same as that of win3.1.
