Recently there was a necessity to install a Virtual CD/DVD on many computers on the same network. And it was necessary, that CD/DVD would be set to the special letter in system. Right now existed a lot of programs which emulate CD/DVD and can mount any CDs/DVD images but as I wished to make all installation and configuration remoutly (well laziness to me to run from a computer to a computer) that was necessity, that the program could setup in silent mode. After small searches has stopped on program ?agicDisc.

I've selected  this program for several reasons:
1. The program is free-of-charge (but not all options work in the free-of-charge version, but what is necessary to me, works)
2. There is opportunity to run setup in silent mode.
3. It is possible to operate all necessary functions from a command line.

For full happiness, and is more true for management of the program from a command line one more file, Miso.exe is required.
The given file can be taken on a site manufacturer ?agicDisc.
For installation I have written a script, INSTALL-V-CD.bat.
INSTALL-V-CD.bat is very simple and contains just one line:

For start of the given script on remote system I use psexec.exe which can be taken here.
After installation ?agicDisc, it is necessary to copy miso.exe to remoute computer. I wish to pay attention, that miso.exe should be located in a directory which is registered in PATH.

Well and now the most interesting. We create virtual CD and assign to it letter which approaches to us. For this purpose I have written one more script, MOUNT-ISO.bat. MOUNT-ISO.bat contains:

@ECHO off
miso NULL -sdrv 0
miso NULL -sdrv 1

For /F "tokens=4 delims=(,) " %%a in ('miso NULL -vlist^|find "[1]"') do Set VCD=%%a

@ECHO select volume %VCD% > %TEMP%\ChangeCDDrive.txt
@ECHO assign letter=S >> %TEMP%\ChangeCDDrive.txt
@ECHO exit >> %TEMP%\ChangeCDDrive.txt

Diskpart /S %TEMP%\ChangeCDDrive.txt

Del %TEMP%\ChangeCDDrive.txt /Q

In my case, i assign to virtual CD the letter "S".
To mount an ISO file, it is necessary to execute a following command:

miso NULL -mnt S: "ISO-IMG.ISO"

The End! :)
