+>This command shows which areas of the flash memory are currently
+not in use. When a block contains non-erased contents it is considered
+in use. Since it is possible to force an image to be loaded at a
+particular flash location, this command can be used to check whether
+that location is in use by any other image.</P

+>Note: </B
+>There is currently no cross-checking between actual flash
+contents and the FIS directory, which mans that there could be a
+segment of flash which is not erased that does not correspond to a
+named image, or vice-versa.</P
