With the HP-UX 11i v1.6 release, the TechSysConf bundle is being introduced as an
always-installed part of the MTOE (and, by extension, the TCOE). By delivering part of
the functionality that was featured in Easy Setup HP-UX 11.0 (product B5532A) for HP
Workstations, this bundle addresses the need of HP workstation and technical server
customers for improved out-of-the-box performance.
Summary of Change

the Technical Computing Operating Environment (TCOE) includes this bundle,
