the drops-x.rd

hi, I use the following command to mount the drops-x.rd in the l4lx26-nitpicker-xorg71.iso: sudo mount -t ramfs -o loop drops-x.rd /mnt but when I change into the /mnt, I find nothing. so someone can tell me how to mount the drops-x.rd or tell me something about the file drops-x.rd ? -- fang,
