If you want to use actual physical floppies and expect to do
special low-level hardware accesses to them (access and use
non-standard formats, for example), then enable this.
Note that the code enabled by this option is rarely used and
might be unstable or insecure, and distros should not enable it.

* Explanation of the logic:

* the range '0' ... '9', 0 otherwise
* we "and" this value with (ch - '0' + 1) --- we have a value 1 ... 10 if ch is
