China DOS Union

Unless there are major technical or user - required changes and additions, this compact version will probably be the final version! If you have suggestions or bugs, you are welcome to provide feedback!

Great! It's getting more and more delicate! I want to collect it.

!!!Strongly recommend not to use in MS-DOS 7.x environment with EMM386.EXE enabled!!!
4.COM = QF.COM + KILLER.EXE + SHELL + Flushing SmartDrv! 4 in 1 Mini Version 523 bytes
4.COM = Format Accelerator V1.08 Format Accelerator Version 1.08 Designed by Luo MingAn (only 523 bytes)

　　1.No need to resident in memory >> Remove itself after use: Convenient Self-removing
　　2.Omit disk check >> Partition and format instantly: Fast Speedy
　　3.Capture abnormal instructions >> Enhance system stability: System Safe CPU-Safe
4.Cache write to disk >> Store data securely: Data-Safe

　　4.com provides an environment shell to accelerate disk operation, and immediately returns DOS memory after running other programs on the command line.
　　4.com accelerates by omitting disk check. Only disk-related operations and commands can be accelerated! Disk formatting always needs to set detailed disk (cylinder, head, sector) parameters. Complex calculations take time, and repeated calls lead to long waiting for users. Omitting disk sector check can complete instantly. Floppy disks, USB drives are also accelerated, no matter how large the hard disk is! Moreover, because it does not resident in memory, it will not produce side effects that the disk check cannot be done when needed.
　　4.com provides chip-level soft safety, automatically captures incorrect instructions during program operation, ends the program that issued the instruction, and returns to DOS. Thus enhances system stability and prevents system crashes.
4.com performs a cache write to disk operation before each run ends. Why? The speed of accessing memory is much faster than that of the hard disk. Store some disk contents in memory, so that when reading disk data, it can first search in the memory buffer, if exists, it is fast, if not, go to the disk; when writing to disk, it is also written to the cache first. In cases where disk is read and written repeatedly, such as when executing compilation or using database management system software, using SMARTDRV is especially suitable. If restart immediately or system crashes, the data may not be written to the real disk ---- that is, lost!

　　4.com is applicable to DOS internal and external commands and tool software, to realize functions such as accelerating partition and formatting. Usage is like:
4 FORMAT A: /S

First, thank you first! I don't know how to use it!! Carsick, right~!!!!555555555555

1) Enter the DOS command line:
4 format A: /s
Means to speed up the formatting of drive A: and transfer system files.
2) Enter:
4
Display a brief help message.

Always remember that in 1995 there was a program called "SMP" - System maintenance Program (also appeared in the software newspaper of 1995 and was for sale). At that time, it could directly display Chinese on the grayscale VGA and automatically use English on the Hercules graphics card. Now it's not just thinking about this program, the more important thing is to study it. WHO has it?

I have been researching and have launched the "Generator of the Program for Displaying Chinese Characters Without a Chinese Character System" (http://www.cn-dos.net/forum/viewthread.php?tid=17591&fpage=1), and please refer to " Can Chinese Characters Be Displayed Without Loading a Chinese Character System? " (http://www.cn-dos.net/forum/viewthread.php?tid=6916&fpage=1).

4.COM(2.53K)--Disk Formatting Acceleration Execution Environment V2006 Designed by Luo Ming'an (C) Fengkuang Software 2006

For usage instructions, see the 18th floor above.

New features:
If there is an EGA/VGA or higher graphics card, Chinese characters will always be displayed (regardless of whether a Chinese character system has been started),
and after using VT technology to display Chinese characters (with multiple fonts <effect see attached picture>), the original system's Western character shape can be automatically restored;
if not, it depends on the Chinese character system to display Chinese characters.
But the help will display English while displaying Chinese characters, which can be corresponding to each other; it is also convenient for use when there is no Chinese character system.

This thing is very interesting.

Ask, has anyone tried using it with smartflp?

What is the acceleration principle of smartflp? It is "to avoid the time waste caused by head idling".
What is the acceleration principle of 4.com? There is a statement in building 18: "4.com provides an environment shell for accelerating disk operation, and immediately returns DOS memory after running other programs on the command line." "4.com accelerates by omitting disk verification. All operations and commands involving disks can be accelerated!"

So, the two are not contradictory!

If anyone has used them together, please post the results for everyone to communicate!

Does it work with gdisk?

I'm learning about Chinese display knowledge without loading a Chinese character system under "DOS". I fished up this post again from the depths! It's not kind to not reply to a good post! Please forgive me!
