/dev/rdsk/f1q15dt IS a valid special device for Interactive, in fact it is 	(under a DOS description) drive B: and a 1.2 meg device.  Dont be so hard
on the guy.  We all had to learn about mknod one time or another, and what
better place than here to share our problems and frustrations?

You are right though, we would like to hear all of your symptoms before we
tie up net band width with fixes that may not apply.

Chances are that there is nothing wrong with the file in question, but rather
with the kernal, or even hardware, but if the file is gone then there is a way.
Look up mknod in you man and follow the instructions found there for rebuilding
your special files.  At the end of this post I will put an example of how it
works, but read the man before you try anything.  If you do a
ls -ol /dev/rdsk/f1q15dt you will find the major and minor numbers listed that
will be used for arguments to mknod ie:

crw-rw-rw-   6 root       1,  1 Mar 28  1990 f1q15dt
crw-rw-rw-   3 root       1, 81 Mar 28  1990 f1q18dt

                          ^  ^

Remember, you must have both BLOCK AND CHARACTER entries for each drive. The
ls listing above is for char, you can find block in /dev/dsk/???????.
