China DOS Union

Operating system environment: DOS under Win98, Win98

There is a DOS program that needs to run automatically when starting pure DOS (press F8 when starting Win98 and select Command Prompt Only).
But when starting Win98 normally (select Normal), it does not run. How to write in autoexec.bat.

If it cannot be realized in autoexec.bat, how to program it with Turbo Pascal 7.0.

Been away from 98 for years and a bit rusty, give a hint on configuring the config.sys multi-choice menu and the method to replace MSDOS.SYS

Hehe, thanks for the reply, but my program is for users to use, I can't replace the user's msdos.sys

2. 1: If you can't touch the user's files at all, there's no other way except F8!

To achieve this goal, a multi-boot menu must be created.

Hehe... Here are the AUTOEXEC.BAT and CONFIG.SYS files from my old computer for your reference:

AUTOEXEC.BAT

@ECHO OFF
PROMPT $P$G
PATH C:\WINDOWS;C:\WINDOWS\COMMAND

SET BLASTER=A220 I5 D1 : Sound card environment variable
SET SOUND16=D:\TOOLS : Sound card driver directory
D:\TOOLS\SNDINIT /B >NUL : Sound card driver
SET TEMP=C:\TEMP
SET TMP=C:\TEMP
D:\TOOLS\MOD CON DELAY=1 RATE=32 : Keyboard acceleration, can be REM if not needed
GOTO %CONFIG%

:WIN98 : WIN98 startup item
C:\WINDOWS\WIN.COM
GOTO END

:DOS : Pure DOS startup item
LH D:\TOOLS\SMARTDRV.EXE
GOTO END

:CD : Load CD-ROM when playing games
D:\TOOLS\MSCDEX.EXE /D:MSCD000 /L:E
LH D:\TOOLS\SMARTDRV.EXE
GOTO END

:END

CONFIG.SYS

MENUITEM=WIN98,WINDOWS 95
MENUITEM=DOS,MS-DOS7.10
MENUITEM=CD,GAME
MENUCOLOR=15,1
MENUDEFAULT=WIN98,5

Thanks a lot. It seems that we can only use this method.
