You must be rootin order to log events to the binary error logger.  This supportcan be enabled one of two ways:<BR>- "<I>enable=diag</I>" option.<BR>- defining the DT_LOG_DIAG environment variable.<BR>If you aren't running as root, nothing gets logged, and no errorsare reported by 'dt' (unless you turn on debug).<BR>Like other exercisers, Q-VET/diskx/tapex, the start and finish ofeach test is logged, as well as any errors encountered.<LI>Fixed a problem in the AIO module when testing with the IOT disc,and the CD-ROM block size was 2048.  The block size on the IOT discis always 512 bytes.  This only effected Tru64 Unix.<LI>Fixed minor problem where "<I>dispose=delete</I>" wasn't parsed correctly.<LI>Fixed problem with setting stderr stream buffered (garbled output).</UL><P><CENTER>Within Compaq, the updated <I>dt</I> kits are located @ URL:</CENTER><P><CENTER><A HREF="http://www.zk3.dec.com/~rmiller/dt.html">http://www.zk3.dec.com/~rmiller/dt.html</A></CENTER><P><CENTER>External to Compaq, you can obtain <I>dt</I> kits from URL:</CENTER><P><CENTER><A HREF="http://www.bit-net.com/~rmiller/dt.html">http://www.bit-net.com/~rmiller/dt.html</A></CENTER></UL><HR><A HREF="mailto:Robin.Miller@compaq.com"><IMG SRC="../gifs/mailbox.gif" ALT="Mail"></A>Send mail to admin of this page: <EM>Robin.Miller@compaq.com</EM> <A HREF="../index.html"><IMG SRC="../gifs/home04.gif" ALT="Home"></A>To Robin's home page.<P>Last modified: December 8th, 1999<HR><H2>Examples:</H2><HR SIZE=5 NOSHADE><PRE>tru64% <B>dia -R -o full</B>	.	.	.******************************** ENTRY    2 ******************************** Logging OS                        2.
