+This is a first attempt to create an `improved' driver for the Mitsumi drives.
+It is able to "live together" with mcd.c, if you have at least two Mitsumi
+drives: each driver can use his own drive.
+
+To allow this "coexistence" as long as mcdx.c is not a superset of mcd.c,
+this driver has to use its own device files. We use MAJOR 20 for it. So,
+you have to do
+
+ # mknod /dev/mcdx0 b 20 0
+ # mknod /dev/mcdx1 b 20 1
+
+and so on, one entry for each drive to support, once.
+
+If you are using the driver as a module, you can specify your ports and IRQs
+like
+
+ # insmod mcdx.o mcdx=0x300,11,0x304,5
+
+and so on ("address,IRQ" pairs).
+This will override the configuration in mcdx.h.
+
+This driver:
+
+	o	handles XA (and hopefully) multi session CDs as well as
+		ordinary CDs;
+	o	supports up to 5 drives (of course, you'll need free 
+		IRQs, i/o ports and slots);
+	o	uses much less kernel memory than the standard mcd driver
+		(no extra driver internal buffers!).
+    o   plays audio (like the `old' driver, I hope)
+
+This version doesn't support yet:
+
+	o	shared IRQs (but it seems to be possible - I've successfully
+                connected two drives to the same irq.  So it's `only' a 
+                problem of the driver.)
+
+This driver never will:
+
+	o	Read digital audio (i.e. copy directly), due to missing
+		hardware features.
