The last option in "Shut Down the System" of Windows 98 can start to the DOS mode, but the DOS started in this way is not very pure DOS. ------------------- How is it impure???

What are the differences and connections between it and F8--Command Prompt only and F8--SAFE MODE COMMAND PROMPT ONLY???

Can it be said that if there are no drivers loaded in config.sys, then choosing F8--Command Prompt only and choosing F8--SAFE MODE COMMAND PROMPT ONLY are the same???

The "Shut Down System" in Windows 98 is actually a very common SHELL mode of applications. For example, it is available in programs like Turbo C and so on. This is obviously not in the pure DOS mode.

"Command Prompt Only" is the pure MS-DOS 7.10 mode.

SHELL mode??? Sweat!!! Don't understand!!!
In short, I didn't test out the difference with its Command Prompt Only, but I felt a big difference from windowed DOS!!!

Also "Can it be said that if there are no drivers loaded in config.sys, selecting F8--Command Prompt only and selecting F8--SAFE MODE COMMAND PROMPT ONLY are the same???"

In the last item of "Shut Down System" to boot into DOS, typing "win" will enter Windows. Doesn't this precisely show that it is a real DOS! What's impure about it!!!!! Please explain specifically~~~~~~~~~~~~~~~~~~~~~~~~!!!!!

Heheh... The shell is a tool for setting up the environment of a command interpreter. That is to say, this method just sets 98 to use command as the command interpretation environment.

So! What are the differences or things that can't be done with this DOS under the overlay compared to the real DOS???

I know that some DOS games can't be played in the DOS window but can be played in the real DOS. I wonder if they can be played in "DOS under the overlay"???
Is "DOS under the overlay" more like a DOS window or more like the real DOS???

Let's take an example. After entering this kind of Shell - mode DOS, you can use the EXIT command to return to its parent program. But in pure DOS, it's impossible to use the EXIT command to leave DOS.

The last option in "Shut Down System" of Windows 98 can start into DOS mode. At this time, the DOS is closely related to the two files AUTOEXEC.BAT and CINFIG.SYS under your C drive.
If there are no such two files in your C drive, then pure DOS can be obtained.
If there are such two files in your C drive, then the obtained DOS depends on the settings of these two files.
If you try to change the settings of these two files, you will find that the available memory and so on have changed.
If there are no drivers loaded in config.sys and AUTOEXEC.BAT, selecting F8--Command Prompt only is the same as it.

That's really good!!! Things are getting clearer and clearer!!!
But according to what the person above said, config.sys and AUTOEXEC.BAT are not useful for F8--Command Prompt only DOS!!!
But I used to hear that config.sys and AUTOEXEC.BAT are not useful for F8--SAFE MODE COMMAND PROMPT ONLY, but are useful for F8--Command Prompt only, which is exactly the difference between F8--SAFE MODE COMMAND PROMPT ONLY and F8--COMMAND PROMPT ONLY
Hope we can clarify this issue together!!!

Sorry! Sent three times at once!!!

"Command prompt only" is the normal DOS mode, and "Safe mode command prompt only" skips loading CONFIG.SYS and AUTOEXEC.BAT, similar to pressing the F5 key at startup.

I didn't say that: config.sys and AUTOEXEC.BAT are useless for F8--Command Prompt only DOS!!!

I just said: If there are no drivers loaded in config.sys and AUTOEXEC.BAT, choosing F8--Command Prompt only is the same as it.

These two sentences have different meanings.

If drivers are loaded in config.sys and AUTOEXEC.BAT, after choosing F8--Command Prompt only, it will select line by line. For very complex multi-menu booting, I haven't tried if it's the same, so there is the above answer.

Just talk about "DOS when shutting down" and "DOS from F8"!!!

From the answers of the above各位, I learned a lot of differences between the two when "coming and going", but I still don't know exactly--what are the substantial functional differences when they are running!!!

If there is no difference, then say that "the DOS when shutting down is not purely completely unnecessary!!!"

Regarding the SHELL method of the application, in short, COMMAND.COM is loaded on top of this TSR program, so it's not very pure.

Haha!!! I understand!!! Such a question is really difficult for people!!! Maybe, just knowing the word "impure" is enough!!!
