+** Copy README, disk1, disk2.vd, disk3.vd, and disk4.vd to the VirtualBox host machine.
+** disk1 (rename to disk1.img) is a boot-able diskette, and used to configure the C:\plan9\plan9.ini or D:\plan9\plan9.ini
+** disk2.vd, disk3.vd, and disk4.vd are files that must be copied to new diskettes (disk2.img, disk3.img and disk4.img).
+=== Notes:
+* Create a blank floppy.img with VirtualBox, for use with FreeDOS:
+** Floppy Drive Device 0:
+** Choose/Create A Virtual Floppy Disk...
+** Floppy Disk Selector (Popup)
+** Create Disk Image (Icon)
+** File Path: (rename the floppy.img as needed)
+** Size: 1.44
+** Format disk as FAT 12
+* Create three copies of the new blank floppy.img (disk2.img, disk3.img, disk4.img):
+* Copy  disk2.vd to the disk2.img
+* Copy  disk3.vd to the disk3.img
+* Copy  disk4.vd to the disk4.img
+=== A VirtualBox host copy example:
+----
+$ sudo mkdir /media/floppy1/
+$ sudo mount -o loop disk2.img /media/floppy1/
+$ sudo cp disk2.vd /media/floppy1/disk2.vd
