       the software installation tools.

       Follow these steps to select a patch for	installation:

	 1.  At	the Inst>prompt, type

	     install patchSGxxxxxxx

	     where xxxxxxx is the patch	number.

	 2.  Select the	desired	patches	for installation.

	 3.  Initiate the installation sequence. Type

	     Inst> go

	 4.  You may find that two patches have	been marked as
	     incompatible.  If this occurs, you	must deselect one
	     of	the patches.
