-/* DEVICE
-   
-   cdrom - readable block device
-
-   disk - readable block device that should be writeable
-   
-   floppy - readable block device that should be writeable
-
-   DESCRIPTION
-   
-   Block I/O devices that model the behavour of a fixed or removable
-   disk device.
-
-   Creating an instance of this device with no arguments will provide
-   access to primative read/write operators.  If arguments are
-   specified then the disk-label package is used to perform abstract
-   disk I/O. The disk-label package will then use this devices
-   primatives.
-
-   For hardware I/O, this device would normally be attached to a
-   parent `bus' and that bus would use the I/O methods to read and
-   write raw data.  The bus might actually be a SCSI or IDE device.
-   It is assumed that the parent bus can take care of DMA.
-
-   PROPERTIES
-   
-   reg = <address> (required)
-
-   <address> is parent bus dependant.
-
-   device_type = "block"
-
-   name = "disk" | "cdrom" | "fd"
-
-   file = <file-name> (required)
-
-   The name of the file that contains the disk image.
