Oakcdrom.sys for Windows 3.1

[kelvinvm04]

Hello!

Anyway, I have Windows 3.1 installed in a Workstation 10 VM. I cannot get it to read the .img file that I made with oakcdrom.sys in it. In the Windows GUI itself, Windows 3.1 will say to format the drive in Flie Manager.

Does anyone have a way to get it into the VM or have a floppy image with that file in it that is compatible with Windows 3.1? If anyone does, I would appreciate it so much!

SIncerely,

Kelvin T.

Just a guess here (I no longer have any DOS or W 3.1 VM's), but perhaps your image is FAT32 and you need to use FAT 16 or 12?

It probably is. I formatted the .img on a NT based operating system (Win 7). Would formatting under Win98 help and adding the  file from that help?

Not sure when they went to FAT32. We used to use winimage, perhaps that does old 16 bit stuff.

I make my images on Linux now:

dd if=/dev/zero of=floppy-144.flp bs=1440k count=1

mkdosfs -F 16 (or 12) -v floppy-144.flp

example:

dd if=/dev/zero of=floppy-144.flp bs=1440k count=1

mkdosffs -F 16 -v floppy-144.flp

Then mount with a loop back device:

sudo mkdir /mnt/tmp

sudo mount floppy-144.flp /mnt/tmp -o loop,noatime,rw

sudo cp <stuff_to_be_copied> /mnt/tmp

sudo umount /mnt/tmp

I can read that diskette in a W7 VM, I don't have a DOS VM to test with.

If you don't have a Linux system, good chance to learn it with a VM. I use CentOS 7.0 as my host

The attached file, "floppy.img.zip" contains a 1.44MB floppy disk image created with WinImage and is formatted MS-DOS (FAT12) and will work in Windows 3.1.
