Contents of this UPDATE (TADCI40-3)     March 1st 1995
        ======================================================


PACKAGE isdn.0295
------- ---------

This is the ISDN software package for the N40, current as of February 2nd 1995.
This is the only full package on this CD, the other files being updates (fixes)
for BOS, NCE and X11. (NOTE: This patch is on hold pending release review)


UPDATE nce.tpn0002
UPDATE nce.tpn0003
------ -----------

These updates allow the use of the ISDN package under NCE. They also fix some
problems present in the A.2 release of NCE2. 


UPDATE bos.tp00003
------ -----------

This update changes installp and ckprereq to prevent the loading of BOS updates
that might affect the correct operation of the N40. This update should be
loaded before attempting to load any BOS updates.  This update will
automatically be loaded before any other update or package on this CD-ROM.


UPDATE sfd.tpd0001
------ -----------

This is an update to the SCSI Diskette Driver package on the AIX 3.2.5 for 
N40 Version A.2 CD.  The update has been issued to support the use of the
1.44Mb capacity external SCSI Diskette unit.


UPDATE x11rte.tpx0003
------ --------------

This package includes new versions of the N40-specific X-Windows modules
which work correctly with updated X servers from IBM PTFs. These versions
allow the installation of IBM PTFs without reintroducing some known problems.



	INSTALLING THESE PACKAGES
	=========================

To install the ISDN package run 'smit install_latest', press F4 and select
the CD-ROM drive as the install device. Enter 'all' in the 'SOFTWARE to
install' field, and select 'yes' or 'no' as required in the 'COMMIT software'
field. Press [Return] twice to complete installation.

You will notice that the installp fix (bos.obj.tp00003) is automatically
installed BEFORE the ISDN package. This is normal.

To install the update packages the process is similar, but the initial
fast-path command will be 'smit install_subsystems'. The device selection
is the same, but in this case the 'SOFTWARE to install' field will be
pre-set with 'all', and the COMMIT flag will be turned off. Press [Return]
twice to complete installation of the fixes.

Note: The default filesystem size of 4MB for /tmp will not be enough for a
successful application of the updates. At least 7.8MB must be free in /tmp.
Use "smit chfs" to increase the size of /tmp accordingly.


	KNOWN PROBLEMS
	==============

There is a problem with the one or more of the IBM originated X11 fixes
removing N40-specific entries from the GAI ODM database. The symptoms are
known to appear when attempting to run the OpenGL extension to X11.

If after running the X-server with the GLX extension installed, attempts to
run OpenGL programs or demonstrations fail with a message like...

  Window type not found!
  X Error of failed request:  GLXBadDrawable (invalid GLX Drawable)
    Major opcode of failed request:  143 (GLX)
    Minor opcode of failed request:  11 (X_GLXSwapBuffers)
    Serial number of failed request:  10
    Current serial number in output stream:  10

...then you should check the GAI database by typing the following command:

  ODMDIR=/usr/lib/objrepos odmget -q 'Adapter_Id = 76021760' GAI

Your screen should list four entries as follows
(the order of the entries is not important):

---------------------------------------------------------------------------
# ODMDIR=/usr/lib/objrepos odmget -q 'Adapter_Id = 76021760' GAI

GAI:
        Adapter_Id = 76021760
        Module_Key = "0x400"
        Module_Path = "loadAncSoft"

GAI:
        Adapter_Id = 76021760
        Module_Key = "ddx"
        Module_Path = "adapter9.r4/loadddx"

GAI:
        Adapter_Id = 76021760
        Module_Key = "rms"
        Module_Path = "adapter9.r4/loadrms"

GAI:
        Adapter_Id = 76021760
        Module_Key = "0x350"
        Module_Path = "3dm5/loadsoftm5"
#
---------------------------------------------------------------------------

You may find that the last entry is missing. To replace it, and correct
the problem with OpenGL, type the following exactly as shown, except
that <Ctrl-D> is typed as a single control key.

---------------------------------------------------------------------------
ODMDIR=/usr/lib/objrepos odmadd 
GAI:
Adapter_Id = 76021760
Module_Key = "0x350"
Module_Path = "3dm5/loadsoftm5"
<Ctrl-D>
---------------------------------------------------------------------------

NOTE: You may have to type TWO Ctrl-D characters to get the shell prompt back.

You will have to re-start the X-server before running any OpenGL programs.
If you start the X-server manually, the command line will be something like:

    xinit -- -x GLX -x abx -x mbx
