2.0   Limitations
-----------------
	  	
        2.1  Browser limitation: If you click on an element that sends you to
             a PDHints link (such as an HTML document), clicking the browser back
             button will take you back to the About Problem determination page 
             and not to your original point.
             Click the browser back button once more to go back to the original
             chart. You can also use the scroll box in the bottom of the frame
             to go back to that page.
       
        2.2  At the time of this release the diagnostic read\write buffer test
             referred to in the HDD Verification PDs is not available.

	2.3  DS300 only; at the time of this release the diagnostic command "Connection"
             does not work and may not be available.
        
	2.4  When running FAStT MSJ read/write buffer test to a controller, the first
             iteration of the test may fail. This will also occur after a "refresh" is
             performed. Thereafter, the test runs normally and will detect read/write
             buffer test errors if they occur.
