Knoppix live cd

hey guys i have a knoppix games live linux dvd........and it is not booting directly from the dvd...........therefore i tried to run the gameskno.iso file through ms dos..........but it sill is not running.....can anyone tell me what is the command (in dos) for running *.iso files in ms dos...........(i have tried simply writing the gameskno.iso and enter).(maybe it is not booting bcos it contains other data as well of windows and linux both and the distro is in a folder and not in the root of dvd)

I don't know if you even can boot it inside DOS, as you may know linux replaces the DOS-kernel, if you're not running a virtual computer only one of them can run at the time. Make sure you've set your BIOS to be able to boot from CD-ROM, and give the CD-ROM higher priority than the harddrive when it comes too boot-devices, then re-try.
