PSE differences at AIX 4.1
Question:
Env: AIX 4.1
Desc: Pat has PSE (Portable Streams Environment) on
her 4.1 systems and she notices a difference from
AIX 3.2.5 when she run the strload command.
Under 3.2.5 she used to get:
dlpi: yes
echo: yes
Under 4.1 she gets:
stddevice: yes
stddevice: yes
stdedx: yes
sc: yes
She would like to understand the difference between these two outputs
and if the 4.1 output gets her the same set up as the 3.2.5 output.
Response:
The strload command loads the drivers and modules listed in /etc/pse.conf.
They are simply loading some new drivers and modules with AIX 4.1.
These files, which list the drivers and modules, are listed below for
comparison:
The /etc/pse.conf file for AIX 3.2.5 is:

\# There are two ways to configure the following drivers and modules. Select
\# only one method.
\#
\# 1. Use different configuration files which do not require rebooting the
\# machine. If you do not want the DLPI driver, the XTISO driver, or the
\# TIMOD module configured after every reboot, use method 1.
\#
\# The DLPI driver can be configured via the /etc/dlpi.conf file using the
\# "strload -f /etc/dlpi.conf" command.
\#
\# The XTISO driver and TIMOD module for tli/xti applications can be
\# configured via the /etc/xtiso.conf file using the
\# "strload -f /etc/xtiso.conf" command.
\#
\# 2. Uncomment the following lines as needed and, after the next machine
\# reboot, these drivers and modules will become available for use. If you
\# always want any of the following drivers or modules configured after every
\# reboot, use method 2.

Please notice that in AIX 4.1 the dlpi and xtiso drivers are commented
out and have different load files (indicated above).
