Dear SCO Customer,

The enclosed Support Level Supplement (SLS) PTF3052, the Crash Utility
Supplement, corrects the crash utility for any UniProcessor or MultiProcessor
SCO UnixWare 2.0 or SCO UnixWare 2.1 system as specified below.

Some commands in previous versions of crash exhibited minor yet disabling 
problems.  For example, the stack trace command would fail to complete a 
trace, or would show a stack trace irrelevant to the system panic under 
investigation.

SLS PTF3052 improves the original crash program, primarily for command 
line and symbol handling. The commands "addstruct", "hexmode", "reduce", 
and "resmgr" have been added.  The command "help" shows a summary of the 
improvements: "help od" describes structure improvements to "od"; and 
"help -e" shows the syntax and title of every command.  


Software Notes and Recommendations
----------------------------------

SLS PTF3052 may be installed on any of these releases:

        SCO UnixWare Application Server Release 2.01, 2.02, 2.03
        SCO UnixWare Personal Edition Release 2.01, 2.02, 2.03
        SCO UnixWare Application Server Release 2.1.0, 2.1.1, 2.1.2
        SCO UnixWare Personal Edition Release 2.1.0, 2.1.1, 2.1.2

SLS PTF3052 contains these files:

        /usr/lib/crash/addstruct
        /usr/sbin/crash

The same PTF3052 crash binary can run on any of these releases, UniProcessor 
or MultiProcessor, to examine that running system, or to examine a system 
dump from any other of these releases.  This version of crash may also be 
run on an SCO OpenServer 5 system to examine an SCO UnixWare system dump 
stored on the SCO OpenServer 5 system.

Note: If the osmp package is installed after PTF3052 has been installed, 
then PTF3052 must be reinstalled to enable the new /usr/sbin/crash 
functionality.
