Hi Chris,
Welcome to PCHF. We have a wonderful team of techs here, and I know we will be able to figure out something.
It would probably be more helpful if you gave us a clearer picture of what it was exactly that you are trying to do.
What the specs are on your machine.
What USB device is it that you are trying to run in DOS?
Why is it that you need the device to work in DOS?
The more information you can give us the better the chance are that we can come up with some clever work around.
Looking forward to your reply,
TTFN
LGW
