Good thought -- thanks.

I have managed to trace it tonight.

The last version Udo Kuhnt released was 7.01-08:

https://archiveos.org/drdos/

The Zip contains what appears to be the image of a boot diskette: DISK.IMG

But it isn't.

First, it's the wrong size. VirtualBox can't mount it. VMware can.

I truncated it to exactly 2880 sectors using the advice from ``jleg094'' here:

VBox mounts that. But neither boots -- it just displays 2 dots.

I didn't think to check what was on the image! Foolish of me.

I mounted it on a pre-booted VM and looked, and it's blank! There's nothing in the image at all.

So, I mounted the empty image file as a loop device, copied the boot files in there and then the rest of the files in the distro archive.

And lo! It works! It boots my VM just fine, and it's now running 7.01-08!

All I need to do now is work out how to make the hard disk bootable, and I'm in business.
