DSL Embedded :: Formatted USB pendrive

Hi all,
I have recently formatted my USB pen drive and thought I had backed up everything on it, unfortunately I do not appear to have saved the .bat file on the pen drive, I have the qemu folder and contents, as well as the DSL files but can not remember what the code was for creating  the .bat file please help. I can get DSL to boot from the pen drive but wish to make it bootable again from within Windows (embedded) do I need to reconfigure anything else?  
It does not matter now downloaded the embedded version again and re-installed 0.9.3. to the USB and works fine
