Dear SCO Customer,

Support Level Supplement (SLS) PTF7046C, the Hotplug Supplement for SCO 
UnixWare 7.0.1, provides hotplug-related fixes for the following problems:

     1. After a hotplug operation is performed, rtpm and sar no longer
        work.

     2. Preferences and refresh intervals are not being saved.

     3. More than one instance of the Hotplug Manager could be run
        simultaneously, which could lead to inconsistent information
        being displayed.

     4. Adapters other than HBAs and NICs could be powered off through
        the Hotplug Manager.

     5. The string "unidentified" in the message catalog is confusing.

     6. Help files in the Hotplug Manager are not accessible.

     7. A memory leak was discovered.

     8. A condition that could cause a core dump was discovered.
