+This fix repairs a bug in the interpretation of the "MCD" boot variable.
+Right now it simply doesn't work, so the Mitsumi driver is locked to
+I/O 300, IRQ 10.  (Note that this is a driver for the old and obsolete
+proprietary Mitsumi interface.  Newer Mitsumi devices are IDE, so don't
+go to the trouble to patch mcd.c to find out that it won't work anyway.)
+
+To apply this fix do the following as bin:
+
+	! cd /usr
+	! patch -p0 < "this-file"
+
+And build a new kernel normally.  You will find the original mcd.c file
+renamed to mcd.c~ in src/kernel/.  You may wish to delete it to clean
+things up.
