Subject:    -3- What should I know before updating to Impressario
                version 1.2?
Date: 18 Aug 1994 00:00:01 EST

  1. If you upgrade a system running Irix 4.0.* or Irix 5.1.* to Irix
     5.2 and you already have Impressario 1.1 installed then
     Impressario 1.1 should continue to work under Irix 5.2.  However,
     you should update to Impressario 1.2 as soon as possible after any
     update to Irix 5.2

  2. Once you upgrade to Irix 5.2 do not remove Impressario 1.1.  If
     you do, you should re-install the following subsystems from the
     Irix 5.2 distribution CD (for convenience these subsystems are
     also found on the Impressario 1.2 CD -- see the next item):

      print.man.desktop print.man.relnotes print.sw.desktop

  3. When you install Impressario 1.2 you will find that it has the
     following subsystems on the Impressario 1.2 CD:

     print.man.desktop print.man.relnotes print.sw.desktop

     As a minimum, install the default print subsystems (do not mark
     all the print product as 'keep' from inst).  The reason this is
     done is that the inst procedure removes all files associated with
     Impressario 1.1.  Some of the Impressario 1.1 files now reside in
     the print product and they will be removed when Impressario 1.2 is
     installed.  So, the print product must be re-installed when
     Impressario 1.2 is installed.  For convenience, the print product
     is supplied with Impressario 1.2 and it will  automatically
     install the correct print product (assuming you do not change the
     set of software to be installed using the inst utility).

     Note that the print product shipped with Irix 5.2 is version 1.2.
     The print product found on the Impressario 1.2 CD is version
     1.2.1.  They are both the same.  The higher version number of the
     print product on the Impressario 1.2 CD ensures that they are
     installed by the inst utility when you install Impressario 1.2.

  4. Do not load Impressario 1.1 (client or server software) onto an
     Irix 5.2 system.  There are OS patches in Impressario 1.1 which
     are not necessary for Irix 5.2.  If Impressario 1.1 is installed
     on top of IRIX 5.2, you should be aware that the following files
     are replaced, and their corresponding Irix 5.2 subsystems must be
     reinstalled.

     File name                               Subsystem
       
     usr/lib/lpsched                         eoe2.sw.lp
     usr/lib/lputil                          eoe2.sw.lp
     usr/lib/print/lptops                    eoe2.sw.lp
     usr/bin/lp                              eoe2.sw.lp
     usr/sbin/mkcentpr                       eoe2.sw.lp
     usr/spool/lp/model/netface              eoe2.sw.lp
     usr/lib/filetype/vadmin/printers.ftr    desktop_eoe.sw.FileTypingRules
     usr/lib/filetype/vadmin/vadmin.ftr      desktop_eoe.sw.FileTypingRules
     usr/etc/rshd                            eoe2.sw.tcp

     IMPORTANT: If you install Impressario 1.1 onto an Irix 5.2 system
     you absolutely must re-install the above subsystems -- installing
     Impressario 1.2 (the correct version for Irix 5.2) will not undo
     or replace the OS patches that Impressario 1.1 installed.

     Note: It is not possible to install a single file from a subsystem
     -- you have to install the entire subsystem.
