Patch Installation Instructions:
--------------------------------
For Solaris 2.0-2.6 releases, refer to the Install.info file and/or
the README within the patch for instructions on using the generic
'installpatch' and 'backoutpatch' scripts provided with each patch.
For Solaris 7-9 releases, refer to the man pages for instructions
on using 'patchadd' and 'patchrm' scripts provided with Solaris.
Any other special or non-generic installation instructions should be

installs a patch to a standalone machine:
example# patchadd /var/spool/patch/104945-02
The following example removes a patch from a standalone system:
example# patchrm 104945-02
For additional examples please see the appropriate man pages.
Special Install Instructions:
-----------------------------
Reboot the system after patch installation.
NOTE 1: To get the full support for logical device namespace for
printers and new printer minor node type, one needs to
install the following patches:
108528-03 (or newer) kernel update patch
108979-08 (or newer) devfsadm, platform nexus, I2C and
Netra ct patch
109880-01 (or newer) forthdebug patch
109883-01 (or newer) ecppsys.h patch
109892-01 (or newer) ecpp patch
109893-01 (or newer) stc patch
109894-01 (or newer) bpp patch
109877-01 (or newer) dma_i8237A.h patch
109890-01 (or newer) pmserver.jar patch
109896-01 (or newer) USB patch
NOTE 2: In rare cases, the serial lines of the SPC may become
hung for no apparent reason. If this situation occurs,
the driver has a mechanism to attempt a recovery that
MAY RESULT IN DATA LOSS. A "deadman" routine can be
made to run periodically; if it detects a hung state a
corrective action can be issued. If you are instructed
by Sun support personnel, the following /etc/system
variables can be set to control the behavior of the
deadman routine:
stc:stc_deadman_enable // defaults to 0, if non-zero deadman will be
// run every stc_deadman_timer microseconds;
// otherwise, the deadman will not run
stc:stc_deadman_timer // defaults to 15000000 (15 seconds)
stc:stc_verbose_deadman // if zero, no deadman-related messages are
// printed; if 1 (default), a moderate amount
// of status messages are printed out; if two,
// even more status messages are printed out.
If you are not experiencing problems, DO NOT enable the deadman
mechanism.
ONLY ENABLE THE DEADMAN MECHANISM IF INSTRUCTED TO DO SO BY SUN
SUPPORT PERSONNEL.
