If it is changed to a bootable CD, how should it be modified? Thanks to everyone first!

Answer your question~~~! Very urgent!

This batch file is actually relatively easy to understand, for example:
@ECHO OFF ;Suppress redundant display information
SET DIRCMD=/O ;Set the environment variable of DIR, so that when executing DIR, it will arrange directories and folders in order
set ramdrv=z: ;Set the value of variable "ramdrv" to "z:"
a:\xmsdsk 4096 %ramdrv% /y /t ;Create a virtual disk, specify the drive letter as variable "ramdrv", that is "z:"

echo. ;Display a blank line
echo Preparing base files to drive Z, please stand by...
echo.

copy a:\io.sys z: >nul ;Copy files to z:, and suppress the display result, the following parts of the statements are similar;
copy a:\msdos.sys z: >nul

mkdir %ramdrv%\bin ;Create a new directory, that is: z:\bin
mkdir %ramdrv%\doscmd
mkdir %ramdrv%\temp
set tmp=%ramdrv%\temp ;Set the temporary folder
set temp=%ramdrv%\temp ;Set the temporary folder
set ebddir=%ramdrv%\doscmd ;Set the variable

set path=%ramdrv%\bin ;Set the command search path
copy a:\command.com %ramdrv%\>nul
set comspec=%ramdrv%\command.com ;Set the command interpreter path
copy a:\readme.txt %ramdrv%\bin >nul
copy a:\readme.bat %ramdrv%\bin >nul

copy a:\extract.exe %ramdrv%\bin >nul
copy a:\device.com %ramdrv%\bin >nul

extract /y /l %ramdrv%\bin /e a:\menu.cab >nul ;Extract files to %ramdrv%\bin (that is Z:\bin)
extract /y /l %ramdrv%\doscmd /e a:\ebd.cab >nul
set path=%path%;%ramdrv%\doscmd

Because the boot CD is booted by simulating drive A, so as far as this file itself is concerned, basically no major modifications are needed. If you want to support the CD drive, you need to add the CD drive driver.

Is this batch script written by pkmater?

Below is the quote of Wengier's speech on 2003-6-5 0:41:05:
This batch script was written by pkmater, right?

Hmm~~~! But I want to make his Chinese bootable disk into a bootable CD!

Because the boot CD is booted by simulating drive A, so for this file itself, basically no major modifications are needed. If you want to support the optical drive, you need to add the optical drive driver.

How to specifically modify and add the optical drive driver?

First, copy the CD-ROM drive drivers (such as Vide-cdd.sys and MSCDEX.EXE/Shsucdx.exe) to the A drive. Then add the following statement in config.sys:
DEVICEHIGH=Vide-cdd.sys /D:MSCD001

Then add in AUTOEXEC.BAT:
MSCDEX.EXE /D:MSCD001 (or: Shsucdx.exe /D:MSCD001 )

MSCDEX.EXE /D:MSCD001 (or: Shsucdx.exe /D:MSCD001) ----> Where to add it in AUTOEXEC.BAT?

The last line of the first paragraph, it is best to use LH MSCDEX.EXE /D:MSCD001.

............
a:\xmsdsk 4096 %ramdrv% /y /t
MSCDEX.EXE /D:MSCD001
Is this so?

Um.. It doesn't matter where. .. This batch file has no variables and no options. ..
