Dosbox last version.
When the "-c" parameter is used with "imgmount" BEFORE the "mount" command, so it works. When the "-c" parameter with "imgmount" is used AFTER the "mount" command, it fails.
Example :
dosbox -noautoexec -noconsole -c "imgmount b C:\dosbox\sb16util.iso -t cdrom" -c "b:\bccvol.exe m2" -c "mount c X:\drivec\" -c "imgmount a X:\drivea\drivea.img -t floppy" -c "a:"
This command line mounts B and C drives, but fails A floppy
dosbox -noautoexec -noconsole -c "imgmount b C:\dosbox\sb16util.iso -t cdrom" -c "b:\bccvol.exe m2" -c "imgmount a X:\drivea\drivea.img -t floppy" -c "mount c X:\drivec\" -c "a:"
This command works
