It's really hard to find.
:mad:Been looking for a long time and still can't find it.
The alliance here is the place where I found the most complete DOS software.
But unfortunately, there still isn't it.
Could any kind person provide it?
:o:o

Asking fujianabc

I want to make the hard disk boot with CDOS. How to install it?

I extracted the image of 1.vfd to a floppy disk. The floppy disk stopped halfway through booting (after detecting the ports).

System configuration: Memory is 32M. The 10G hard disk has only one 450M partition allocated for installing CDOS, and the remaining space is unallocated.

The DOS compatibility here seems not very good, most machines can't boot, and neither VPC nor VMware virtual machines can start. The screenshot of the failed start is probably like this:

I only successfully started it in QEMU. There is an installed QEMU image and a stripped-down version of QEMU in that rar. Just run "Start QEMU.cmd" to start it. The effect is the same as the screenshot on the 3rd floor.

It's really a last resort. There's a software that requires this environment.
The old hard drive died the other day.
So I've been searching everywhere.

Found some installation instructions http://www.conctrls.com/CDOSFAQs.html
It seems the hard drive needs to be less than 4GB, memory less than 48MB, and the hard drive should have Ultra DMA turned off.
I followed the instructions, but there's no improvement.

You might as well try "Digital Research - MultiUser DOS v5.10", which can be regarded as an upgraded version of "Digital Research Concurrent DOS v3.01". For details, see the following post, which talks about some relevant contents:
http://www.cn-dos.net/forum/viewthread.php?tid=20730&fpage=1
The download address is on the 11th floor.

The link is no longer accessible. Is there anyone who can provide a boot disk of CONCURRENT DOS 386?
