427.0. "BNU ACCVIO" by CUJO::SAMPSON () Wed Mar 05 1997 20:59

	Hello,

	We recently received new March '97 documentation CDs for OpenVMS Alpha.
A new utility, BNU, is provided in the [SETUP] directory.  I installed this
utility on three system disks.  It works on the OpenVMS VAX V7.1 systems, and
on one of the two OpenVMS Alpha V7.1 systems (DEC 3000-500).  However, on the
other (AlphaServer 2100 4/200), it dies with an ACCVIO while starting up.

	I have compared the images between the two Alpha systems, and have
found that they are identical on disk.  The ACCVIO also persists after a
system reboot.  SET WATCH FILE/CLASS=MAJOR reveals that the ACCVIO occurs
after BNU tries and fails to find a file (probably in "DECW$USER_DEFAULTS"),
but before BNU would have found (on the system where it works) LIBRARY.ODL
(probably in "DECW$SYSTEM_DEFAULTS").  I have modified this LIBRARY.ODL to
(partially) integrate it with our existing Bookreader library.  However,
I've also confirmed identical configurations and file protections on all
three systems.  The system (most likely the software environment) on which
BNU fails must be defective in some way, but I have yet to determine how.
The DECW$DISPLAY settings do not seem to matter; the program blows up well
before bringing up the window.

	I've logged a call with the CSC: C970305-3976.  RHETT::WEST is
working the call, and is looking for help from the BNU developers,
since it is also new to the CSC, and they are already getting some calls
about it.

	Here are two ACCVIO's.  The first occurs at an S0 PC address.
The second was obtained by activating private copies of all interdependent
resident images, and so occurs at a P0 PC address.  Either way, they both
occur at offset 448E4 in image DECW$XTLIBSHRR5.  ECO ALPMOTF01_U4012 has
been applied on both Alpha systems.  ECO VAXMOTF01_U4012 has been applied
on the VAX system disk.

	Thanks in advance for any help,

	Hello BNU/DECwindows Engineers,

	Raymond RHETT::WEST has asked me to ask you to please provide
us with some help in diagnosing this BNU ACCVIO, and possibly updating
the FAQ in topic 432 with any generally useful information gained.

	Since you're the only people with access to the source code,
you're the only ones who can help with this issue, and others like it.
Raymond says they've received about 300 CSC calls so far on BNU, and
they can really use your help.

	Thanks,
	Bob Sampson
