China DOS Union

Who can make a disk like this with the following requirements:

1. Made with a 3.5" floppy disk (capacity 1.44M)
2. Chinese support
3. Has a menu on startup
4. Includes the most games or other computer utility software. Tools are not needed because it's for a computer training department, not for repairing computers

Hehe, quite an interesting attempt. First, the owner of the post should note that the capacity of a floppy disk is definitely not 1.44 MB, but 1.38 MB, approximately 1440 KB. Then let's calculate:

The core files of the DOS system (including Autoexec.bat, Config.sys, and Himem.sys): about 240 KB
Small Chinese system (China Dragon, without input method): 53 KB
Remaining space is approximately: 1440 - 240 - 53 = 967 KB

Okay, it's up to the owner of the post to decide what to fit into less than 1 MB of space, because I don't know what the so-called "practical" software refers to. Wengier's MSDOS 7.1 boot disk comes with many small utility software, which is also quite practical. As for DOS games, I only know that the more fun Super Mario also requires 64 KB, and I don't know other games. If the size of the tool is relatively large, you can compress it.

Methods like creating virtual disks can be used, and programs can be packaged with compression software. There's no need for utility software.

The practical software I think includes:

Typing practice for Wubi/English, computer learning, Super Mario, etc.

There's a compression software in HIREN 'S CD with a very high compression ratio.

Using a virtual disk is inevitable, otherwise where would we get so much space? The tools in Hiren’s CD seem to be UHA format compressed archives. This format seems to be even better than CAB and RAR, but I haven't looked for the compression tool.

The UHA format is very commonly used. You can find uharc by searching. Many hard disk version game CDs are compressed with this. Many people have also written GUIs for UHA under Windows, and many versions can be found online, such as winuha, etc.

As for virtual disks, maybe it's better to use something like grub + memdisk to call an img image stored on a floppy disk (img files can be compressed with zip/gzip). If space is tight, it is recommended to use syslinux instead of grub.

The advantage of this is that the DOS system files and the used drivers are also compressed in the img, and the DOS ramdisk program can be omitted, and instead, memdisk, a BIOS-level ramdisk, is used.

There are racing games / Super Mario / Minesweeper / Wubi practice / English typing practice / keyboard recognition practice / Gobang

I used the CAB format to compress it. As for the UHA format, I know it is related to the uharcd program, but I am too lazy to figure out how to use it, so I will try this first.

I hope some expert can make a disk including more software. What the person above said makes sense, and I hope to make such a disk.

I don't know much about GRUB.

In addition, you can use hd - copy to make the floppy disk reach 1.72M, and use 2mf.exe to format it to 1.86M; it's not just 1.44M.

The key is that the quality of floppy disks nowadays is not good. After formatting, after being used a few times casually, the track 0 is damaged.

It's not bad to be able to be placed in the CD bootable disk.
