Hi Peter.

I am using "any to iso" - and it works very fine for me 😀
It also works with Disc-Images.

Thank you for the reply, but I think I just found a workaround though. While DOSBox is a wonderful emulator some things about it can be rather confusing. To me at least.

um I mount multiple floppy disk images in dosbox all the time.. just use the swap disk command to change images. ctrl-f4 or something. its in imagemount.

imgmount a: disk1.img disk2.img disk3.img disk4.img -t floppy

cltr-f4 goes to next image.

This is not supported even in the latest released version, only in SVN.

@BloodyCactus: that might be, but it seems my *.img files are a different type of *.img than yours. I can't mount more than one at a time.

@ulfenknulfen:

"Any to iso" isn't working. I'm beginning to suspect the issue might be with the *.img files themselves. I uploaded a single *.img file to: https://drive.google.com/file/d/1SZVS90hzBAjE … iew?usp=sharing. While it is very old program (Microsoft Visual Basic 3.0 Professional) I doubt I am allowed to share the full installation package here. Can anyone have a look and tell me their findings?

Maybe it wasn't clear before the way I wrote it: download and use an SVN version of dosbox https://www.dosbox.com/wiki/SVN_Builds and you'll be able to mount multiple floppy images. The released version of dosbox simply doesn't have this feature.

Yes, I agree: using the SVN version of DOSBox is by far the simplest solution here. (You can also try alternative builds based on the SVN, like DOSBox-ECE or DOSBox-X.)

Virtual Floppy Drive also used to be a useful solution for problems like this, but it hasn't been updated in a really long time and I don't think it works under Windows 10.
https://sourceforge.net/projects/vfd/files/

It looks like there's a newer version as well?
https://sourceforge.net/projects/simplifiedvfd/

But I guess OSFMount really does the same thing, come to think of it. And in any such case the solution is simple: mount the .img as a drive in OSFMount, mount the drive as a floppy in DOSBox, and then swap images in OSFMount when you want to swap images in DOSBox.

I might add that even if you do extract all the files from a .img, you'll probably want to convert them to a BIN/CUE image rather than a ".iso". It is also probably important to make sure that the label of the image is the same as the volume label of the floppy image – which can be problematic, because some BIN/CUE creators are more picky about the range of characters they will accept. But, again, you will probably not want to do this since it is vastly easier to use an SVN build of DOSBox.

Also, questions like this should probably be in the DOSBox subforum rather than the DOS subforum.

Keep in mind that you are not allowed to skip letters when mounting drives.
An example with lots of diskette images mounted for a Windows 3.11 install on the normal DOSBox 7.4:

c and d are already mounted as C:-drive and CD-Rom.
Like this it's possible to have most games and programmes installed that come on several diskettes by just changing the drive letter during the setup if it allows you to.

@konc: there appear to be lot of SVN builds. Which one do I need?

@BardBun: I will try that trick, it might work. - The Setup won't allow me to specify a drive letter... So this won't work.

Just get a plain/vanilla, for example EmuCR

@konc: all sorts of things pop up on that site, but no DOSBox download...

@konc: thanks

@Konc, again thanks for the SVN version of DOSBox. I can now mount my *.img files all in one go... but... Now my keyboard won't work once Windows 3.11 has started. And the mouse cursor appears to be sluggish. What could be going on?

EDIT:
The backspace key only deletes one character at a time at the "DOS" prompt... Does that SVN version have unusual keyboard settings?

Wouldn't it just work to mount the img than rip it with PowerISO into your desired format?
Or open it then "Save as..." in your desired format?

Once you have finished installing Windows, you can switch back to the regular version of DOSBox since you do not need the extra support for .img files anymore. That way you can find out if the problem is due to some change made in the SVN version.

If I'm not mistaken, PowerISO does not support ripping floppy images or opening floppy images, so no, that would not work. (If it supports .img files, then those would be CD-ROM images in a format that also happens to use the .img extension.)

@jorpho: installing Windows was never the problem. It's installing Microsoft Visual Basic 3.0 Professional whose setup contained on those *.img files. Yes, I could switch back to regulard DOSBox, once I have managed to install vb3prof but I need the SVN DOSBox for that. But like I said, the keyboard isn't working in Windows with that particular DOSBox version. The bizarre thing is I could install Windows 3.11 just fine. It's just once Windows has started the keyboard won't work preventing me from installing vb in spite of having mounted multiple disk images. Also, the backspace is acting weird in SVN DOSBox, it will only delete one character even if I keep it pressed down, it shouldn't work like that normally.

In summary:
-Windows' keyboard won't work in SVN DOSBox.
-It will work in regular DOSBox.
-I can mount multiple imgs and start vb setup, but can't finish it because the keyboard won't work. (svn)

I see. Well, the point of the SVN build is that it changes all the time, so it's possible that some recent change affected the way the keyboard worked in Windows 3.x.

Support for multiple .img files was added to SVN builds a long time ago, so you can try looking for an older SVN build – but I would suggest trying DOSBox-X instead. (It is probably better than standard DOSBox if you want to run Windows 3.x anyway.)
