My university gave ma a DreamSpark account, so i'll finally be able to download a true clean version of MS-DOS to Mount in my usb device, and then readapt my autothing.bat etcc;

But it comes in a strange way:

there is an auto-extract .exe that gives 2 folders. One "UPGRADE" holds all commands like keyb, format, unformat, undelete, chkdsk etcc.. The second "DISKS", contains .img files named "12UPG1.IMG" up to "12UPG4.IMG" and  "144UPG1.IMG" up to "144UPG3.IMG", plus a file called DSKIMAGE.EXE that i can't run from windows10 64bit nor with Windows7 64bit. Last in the same folder there are 2 batch file with commands that didn't help my understanding:

 

Make14.BAT:

echo off
if "%1" == "" goto usage
echo Insert 1.2M disk for INSTALL 1 in drive %1 
pause
echo Creating MS-DOS 6.22 Install Disk 1.
dskimage 12UPG1.img %1
echo Insert 1.2M disk for INSTALL 2 in drive %1 
pause
echo Creating MS-DOS 6.22 Install Disk 2.
dskimage 12UPG2.img %1
echo Insert 1.2M disk for INSTALL 3 in drive %1 
pause
echo Creating MS-DOS 6.22 Install Disk 3.
dskimage 12UPG3.img %1
echo Insert 1.2M disk for INSTALL 4 in drive %1 
pause
echo Creating MS-DOS 6.22 Install Disk 4.
dskimage 12UPG4.img %1
echo Finished.
goto end
:usage
echo.
echo Usage	MAKE12 drive:
echo.
:end




MAKE12.BAT

echo off
if "%1" == "" goto usage
echo Insert 1.44M disk for INSTALL 1 in drive %1 
pause
echo Creating MS-DOS 6.22 Install Disk 1.
dskimage 144UPG1.img %1
echo Insert 1.44M disk for INSTALL 2 in drive %1 
pause
echo Creating MS-DOS 6.22 Install Disk 2.
dskimage 144UPG2.img %1
echo Insert 1.44M disk for INSTALL 3 in drive %1 
pause
echo Creating MS-DOS 6.22 Install Disk 3.
dskimage 144UPG3.img %1
echo Finished.
goto end
:usage
echo.
echo Usage	MAKE14 drive:
echo.
:end


Any idea about how to get it working?

You will never be able to run Dos in Windows 7 64bit or Windows 10 64bit unless you run it in a Virtual Machine. The img files with a prefix of 12 is for creating 1.2mb floppies and the 14 prefix files are for creating 1.44mb floppies. That is why you only have 3 14.img files and 4 1.2.img files.

 

Obviously you do not have a floppy drive to install DOS so you will need to do it Virtually. I am not sure how Virtual Box runs on Windows 10 but see this guide. You use the .img files on a virtual floppy drive.

Lol i'm not trying to run an operating system inside an operating system xD

Have you read my post at least?

" to Mount in my usb device "

 

I just thought the .exe was to directly mount the images in user's chosen device, or even to get them in a single iso to mount, or something like that.

But apparently it isn't

You can't mount those img files to a USB flash drive. Even if you could mount it on USB it would never run on your 64bit OS. I think your best chance would be to create a bootable USB flash drive with Freedos. You may be able to test .bat files with it. Use Rufus with a flash drive and boot it to FreeDos. Not sure it would work for your .bat files though.

Even if you had a iso of Dos6.2.2 you would need to create a virtual machine to run it. Actually using Virtual Box is not that bad. It's fairly easy to run and create a Virtual Machine of DOS.

Ehm... again i've never told i want it to run under Windows. I perfectly know how os works, thanks.

But maybe you have never heared about "bootable usb devices". I can guarantee you that they can work whatever is the os installed in you hard drive, simply because it has nothing to do with the usb booted device. You can even cut hard disk's cables and the bootable usb device will work (or if you don't want to be so extreme just remove them).

Now again, to someone who knows what im asking, can you help me understanding how is this version built and how to mount it in my usb device?

Sorry for the misunderstanding on my part. 

 

Creating a USB bootable flash drive with the FreeDos OS is what I was referring to when mentioning Rufus which I have also used to boot various linux distros.
 

I am not sure how to mount multiple DOS 6.22 img files so they can be installed to a USB flash drive unless you can find a full iso of DOS 6.22 and use that with Rufus. Hopefully somebody on the Forum can tell you how to mount the img files and proceed to install on a USB. Good Luck.

 

Edit: If you want, try the following. Go here and download the MSDOS 6.22 iso file. Use Rufus with the iso image to create a bootable USB flash drive. Here is the contents of the iso file.

It is one of the many i've tryed before getting dreamspark. But it doesn't work properly. Actually the only dos version i was able to run decently came with "Make USB Bootable.exe" which does what the name suggests starting by an user chosen folder, and not an iso. The standard folder that comes with the program has the 3 basic files to run dos. Stilly it gets very little compatibility since it doesn't result as dos6.22 (keyb doesn't work for example).

 

I've tryed to extract the .img files downloaded from dreamspark, and use Make USB Bootable.exe on the folder with no results. Then i've tryed making a single iso out of the extracted files using MagicISO planning to mount the iso on my usb using Rufus; Rufus doesn't even start, it says it's not a bootable image. Maybe i've to create the iso in some special way?

Are you saying that Rufus does not recognize the bootable iso I linked to as bootable?

 

If you want to make the iso bootable, I believe you need to point Magiciso to a boot file that would be extracted from a bootable floppy disk or you can extract the boot image from a bootable CD. If you burn the iso of Dos6.22 I linked to it should give you a CD with a bootable image you can extract. I think you can even use an image from a bootable floppy. You don't have a floppy drive but I do have a bootable floppy that I could extract the image from if the CD image does not work. I can upload it to Dropbox and provide the link as long as MagicIso will allow me to do it in demo mode. I have Poweriso and do not know if the boot image files are compatible.

Can you use the iso in Post#6 and Rufus to create a bootable USB flash drive? This may be enough to check your .bat files.
