-The {{{flags</code> field provides a private set of flags a specific low level device handlers for a device may need. The {{{base</base> is the base address of the device. Its definition depends on the low level device handlers for a specific device. The {{{size</code> field defines the number of bytes of storage the device provides in bytes. This is the raw number of bytes available to the driver. The {{{nv_ops</code> is a set of handlers for the specific device.
+The fields are:

 The NV Disk device requires a set of handlers for each type of device. The handles can manage more than one device in a disk or disks. The handlers are:
 
-  {{{int (*read) (uint32_t device, uint32_t flags, uint32_t base, uint32_t offset,
-                     void* buffer, uint32_t size);</code>
+  {{{int (*<i><b>read</b></i>) (uint32_t device, uint32_t flags, uint32_t base, uint32_t offset,
+ ::                  void* buffer, uint32_t size);</code>
  : Read a block of data from the {{{offset</code> in the {{{device</code> with the {{{base</code> address to the provided {{{buffer</code>.
 
-  {{{int (*write) (uint32_t device, uint32_t flags, uint32_t base, uint32_t offset,
-                      const void* buffer, uint32_t size);</code>
+  {{{int (*<i><b>write</b></i>) (uint32_t device, uint32_t flags, uint32_t base, uint32_t offset,
+ ::                   const void* buffer, uint32_t size);</code>
  : Write a block of data to the {{{offset</code> in the {{{device</code> with the {{{base</code> address from the provided {{{buffer</code>.
 
-  {{{int (*verify) (uint32_t device, uint32_t flags, uint32_t base, uint32_t offset,
-                       const void* buffer, uint32_t size);</code>
+  {{{int (*<i><b>verify</b></i>) (uint32_t device, uint32_t flags, uint32_t base, uint32_t offset,
+ ::                    const void* buffer, uint32_t size);</code>
  : Verify a block of data provided in {{{buffer</code> against to the data at the {{{offset</code> in the {{{device</code> with this {{{base</code> address.
 
 The <tt>nvdisk-sram.h</tt> provides a set of handlers suitable for static RAM.

+To configure a NV disk add this following to a source file in your application. The configuration items are:
+
+# Block size. This is normally 512 for the MSDOS file-system.
+# Number of device descriptions.
+# Pointer to the device descriptions.
+#
