Hi Adoudou,
I have taken a look at an existing disk used to support a local M1700XLi, and it does not appear to contain anything odd/special.
We use a 1.44Mb disk with an executable in the root, and a config file contained in a start up folder (spookily named START_UP).
I'm happy to send them if you have yet to achieve a resolution (please give an email address)
