 infamous "Level 2 Upgrade" left off, and incorporates most all of the
 known features of that never-officially-released version of OS-9.
 
+DISTRIBUTION
+============
+There are two single-sided 35 track DSK images ending in '_ss35_1.dsk' and
+'_ss35_2.dsk' for disks 1 and 2, respectively.  This correspondes to
+the older Tandy method of distributing the operating system.
+
+The other disk image ending in '_ds40.dsk' is a double-sided 40 track
+disk image that contains all of the files found on single-sided disks
+1 and 2.  This is useful for those who have double-sided drives and
+want the entire operating system to reside on one disk.
+
+USING THE DISK IMAGES
+=====================
+All images will work with Jeff Vavasour's CoCo 3 emulator as-is.  If you
+wish to transfer the 35 track disk images to a 5.25" or 3.5" floppy disk
+for use with a real CoCo, and have a Linux system equipped with such a
+disk drive unit, follow the steps below (root login is assumed):
+
+1. Download and install the latest version of fdutils from
+   http://fdutils.linux.lu/
+
+2. Once installed, edit the /usr/local/etc/mediaprm file and add the
+   following lines at the end of the file:
+
+     "COCO360":
+      DS DD sect=18 cyl=40 ssize=256 tpi=48 fm=0 gap=8
+
+     "COCO720":
+      DS DD sect=18 cyl=80 ssize=256 tpi=48 fm=0 gap=8
+
+3. Insert your blank floppy into the drive on your Linux box.
+
+4. Type the following command:
+
+             setfdprm /dev/fd1 coco       (35 Track SSDD floppy disk)
+                    OR
+             setfdprm /dev/fd1 coco360    (360K 5.25" floppy disk)
+                    OR
+             setfdprm /dev/fd1 coco720    (720K 3.5" floppy disk)
+
+   This assumes your floppy drive is /dev/fd1.  You may need to make
+   adjustments to the above commands for your environment.
+
+5. After typing the setfdprm command, the floppy drive unit should spin
+   for a second then stop. Type this command:
+
+             dd if=<diskimagefile> of=/dev/fd1
+
+   Where <diskimagefile> is the image file you want to transfer to the
+   floppy disk.  The image file transfer should start.  When it is done,
+   take out the disk and try booting your CoCo with it.
+
+Repeat steps 3-5 for each additional disk.
