Thanks to Stephen Trier for pointing this one out to me.

Meaning that hd will currently work only on text files :-(

Here is a context diff that will cause "patch" to change hd.c, all that is
needed is the -DMSDOS flag added to your msdos makefile.
run:

patch -c hd.c patchfile

If you don't have patch then there are NOT a lot of changes to make by hand :-)

Thanks again to Stephen

Keep Enjoying!

Pete.
