China DOS Union

I downloaded and installed DOS 7.1 from the internet. When I use DOS to boot another system, it says I'm using virtual8086 and can't boot another system. What should I do to make it work? I just started to learn about DOS.

I would like to add something: I mean I just use DOS to boot but not enter DOS, and then enter another operating system. This has puzzled me for a while. The system prompts me: "RTTarget-32 DOS Boot Utility 5.09(c)1996,2006 On time informatik GmbH cannot boot RTTarget-32 from virtual 8086 mode.
Don't know where the problem is
I added "cd c:\xpcfiles xpcboot xpctgo.rtb" in the autoexec.bat file to start the operating system I want to boot, and the system gives the above error message and has already entered DOS. Can someone help solve it.

Deleting the configuration file config.sys doesn't work either. Can't figure it out

RTTarget-32 is what system? What environment is required to start it? Please figure out the second question in detail.

You don't understand DOS, and others don't understand the thing RTTarget-32 either.

It is a real-time operating system kernel that comes with the MATLAB toolbox xpctarget. Specifically, I don't know much about it. The MATLAB help documentation doesn't introduce it much. I heard it was specially made by MathWorks for their real-time development.
It is just to let DOS boot to guide and start the RTTarget-32 kernel, and it doesn't support virtual 8086 mode.
1. DOS editor
2. The format program
3. The fdisk program
4. The sys program to transfer a DOS system onto another drive, such as the hard disk drive
These are the needed DOS files. config.sys is not necessary.

After installing DOS, generate files like xpcsgo.rtb, xpcboot.com, autoexec.bat in MATLAB on another machine and put them into a floppy disk. Under the DOS system, operate as follows:



#

mkdir C:\xpcfiles

#

Copy files to C:\xpcfiles. For example, type

copy A:\xpcsgo.rtb C:\xpcfiles
copy A:\xpcboot.com C:\xpcfiles
copy A:\autoexec.bat C:\xpcfiles

#

If you want the kernel to run when you press the Reset button on your target PC, save a copy of the file C:\autoexec.bat to a backup file, such as C:\autoexec_back.wrk.
#

Edit the file C:\autoexec.bat to include the following lines. Adding these commands to C:\autoexec.bat directs the system to load the kernel from C:\xpcfiles.

cd C:\xpcfiles
xpcboot xpcsgo.rtb

If anyone has DOS6 installed on a floppy disk, please send me a copy: myl1977@sina.com. The ones downloaded from the internet can't be put onto the floppy disk. Running hdcopy on my machine goes wrong (even the ones that can run under Windows don't work well on several machines), so depressed.

There is actually such a system in MATLAB , I'll take a look when I have time. Now I don't have this toolbox installed in my MATLAB.

As for DOS 6, there are many here, you can just search for it casually.

I solved it, but the RTTarget-32 kernel of MATLAB loads part of it and then restarts. I don't know what's going on. Now I'm very headache.

I added this toolbox to my MATLAB, and then found the file you mentioned. It can be loaded under MS-DOS 7.1 without any config.sys and autoexec.bat (although I don't know what this is).

It seems this has little to do with DOS. You should go to the MATLAB-related forum for help instead of asking this question in the DOS forum

How did you do it? I'm not using config now, and the restart occurs when loading the MATLAB kernel. Can you give me a detailed explanation? I think what I did should be fine. The kernel has been loaded, but there's still an issue. This shouldn't happen. My email: myl1977@sina.com

What version of MATLAB are you using? What about the xpctarget version?

I'm using the latest MATLAB 2009b x86.

Just as you said, I put xpcboot and xpctgo.rtb on drive A:, started MS-DOS 7.1, and executed
xpcboot xpctgo.rtb, then the above interface appeared

Isn't this playing a trick on me? When I start it, it just doesn't listen. I copied those several startup files to the hard drive and added xpcboot xpctgo.rtb, the kernel command to start it, in the batch file. Before the kernel is fully loaded, it restarts again. I'm really fed up.

Use the DOS 7.1 CD version in the new DOS era. Can dual-boot with XP/2K/2K3
