DOS doesn't like my ISO files...

Postby DeBedenHasen » 13. Sep 2016, 18:14

Hello, dearest VirtualBox community!

I'm coming up with the first of many unfixable problems on the forums. So, current status:
  • DOS 6.22 successfully installed by image files
  • ISO file with user created data inserted in the secondary master slot of the machine as a second disk (state: non-bootable)
  • 4 GB of base hard drive memory (Virtual Hard Disk) | 2 GB have been allocated to the system memory

I tried out EVERY drive label (except A: and C:) but none of them lead to the ISO file. Even restarting the VM didn't help.

Have you encountered the same problem? Could you fix it? If yes, please, let me know!

DOS does not have native support for CD drives. Have you installed the appropriate DOS device drivers?

Drivers? I didn't even know there were drivers for this... Where can I get them from?

It's a long time since I set up a CD drive in DOS.

There are two drivers required: at the device level you need something to control the CD hardware: ISTR the Oak CDROM driver works for the VirtualBox simulated drive.

You also need MSCDEX, which is the higher level driver that allows DOS to talk to the low level driver. This is bundled with later DOS releases, but not configured by default.

Google is your friend for the details.

I have a DOS 6.22 VM on my home PC, which I've now checked. I put all my CD drivers in a folder called CDROM on the C drive.

Here is my CONFIG.SYS text file.

This was not exactly what I wanted to do, but the I tried making a real CD out of my data, but I suddenly realized that my CD-ROM device can NOT burn disks...
I had to reinstall the driver several times because DOS removed it over and over again. Every restart of the machine deleted the driver files for some unknown reason...
At least moving the driver into [C:\CD] worked immediately. (Wow...)

Summary:
Driver installed.
Couldn't create the CD.

How to fix:
Insert CD into CD-ROM drive.
Shut down the PC.
Throw it out of the window...

Or just find your rusty old notebook and create the CD there... I think I should rather do that...
