I would like to find my usb stick but i can't list it with " DIR" , do you know a command that could help me to find it ? i tryed to acces with "cd D:\" but it doesn't find it . then, do you know if it is possible to run an iso file or to burn a disk with freedos ?
FreeDOS and just DOS in general does not support the syntax of cd D:\ you would just need to enter your drive letter in this case D: and press enter, at the prompt and that should allow you to view the contents of your drive. As far as burning an image I am not sure why you would want to do that under DOS anyway, however I think there is a port of the Unix dd command available for FreeDOS in which you could write the iso files to a disc.
If you have already figured this out by now that is great! otherwise i hope this answer helps
