Dear SCO Customer,
 
Support Level Supplement (SLS) PTF7078A, the UnixWare 7.0.0 ca Driver Patch,
partially addresses a problem where the Real Time Clock (RTC) drifts and CMOS
may get corrupted.  The problem is due to multiple drivers accessing ports
without sufficient protection for mutual exclusion.  SLS PTF7078A provides a
new ca driver.

Note: SLS PTF7077A, the UnixWare 7.0.0 cram Driver Patch, is also required for
      a complete solution to this problem.

Note: This SLS should be installed on UnixWare 7.0.0 only.  For systems
      running UnixWare 7.0.1, see SLS PTF7075A and SLS PTF7076A.

The release notes displayed prior to installation can be found in:

        /var/sadm/pkg/ptf7078/install/ptf7078.txt


SLS PTF7078A contains:

        /etc/conf/pack.d/ca/Driver_atup.o
