Recently I stumbeled onto a program for DOS with which I made a sucessful bootable copy of my Emax 3.2 os disk. I'm sending  a copy of the shareware and the disk image of my Emax 3.2 os to see if it will work on the your end. There is instructions included with the software. You will have to work in DOS not a DOS window. Unzip the file to your root directory. I use the root directory it is easier. The command line syntax for copying the image file to floppy will be as follows:

COPYQM A: PLAYBACK=C:Zd700_3.2os BIOS

Watch the spacing: COPYQM<space>A:<space>PLAYBACK=C:Zd700_3.2os<space>BIOS

Zd700_3.2os is my image of the Emax I disk with the standard Emax 3.2 os on it
BIOS is a command to the program.

To make the disk image I used the following command line from the DOS prompt:

COPYQM A: RECORD=C:Zd700_3.2os BIOS

Again watch your spacing: COPYQM<space>A:<space>RECORD=C:Zd700_3.2os<space>BIOS
Both processes take quite a while to do but the results should be well worth it.

You'll have to unzip the file then you will have to unzip Copyqm.zip. Do this in the root directory (folder) as you can use the commands as they are written in this text.
