Nice :-) > Is there such a variable or can you tell me how to set > this variable automatic in batch? I do not remember one, but it is extremely easy to do: Run the bootdev.txt file shown below once: a cs:100 mov ax,3305 int 21 add dl,40 mov [0118],dl mov ah,09 mov dx,0118 int 21 mov ax,4c00 int 21 db "?:",0d,0a,"$" r cx 1d n bootdev.com w q Note the empty line before "r cx". X:\>debug < bootdev.txt ... Writing 001D bytes. ... Now you can use the following command: X:\>set /e bootdevice=bootdev Bootdev.com simply prints a string like "C:",CR,LF which is then stored in a variable, as you can see: X:\>echo %bootdevice% C: FreeCOM and CMD support SET /E, not sure about other / older command.com variants here. Eric PS: A similar trick can be done with my GETARGS tool to fetch MEMDISK "Linux kernel options" (memdisk is booted like Linux) into a variable inside DOS ;-). ------------------------------------------------------------------------------ Create and Deploy Rich Internet Apps outside the browser with Adobe(R)AIR(TM) software.
