For Linux, define the cd rom in the resource manager.
However, being that this drive is not recordable, define it as such.
In the record command type:
cat > /dev/null.
Set the record buffer to 1000.
Then run RecoverEDGE, select Configure->Boot Media.
Select the cdrom device and you will notice the device node gets filled in automatically.
Back out, then select Make Disks. Your image will be found in /usr/lib/edge/recover2/cdrom.img.
