Keywords: POINT fast wide st multi-initiator
Synopsis: SunOS 5.4: Point Patch for st for Fidelity Investments
Date: Sep/19/95

  NOTE: =========> Special Note:
	This patch is not intended for general use.  It has been built to fix
	bugs and supply required enhancements for Fidelity Investments and
	STK for fast/wide tape on Solaris 2.4.  The enhancements here will
	not be needed by most customers.

	The administration of this patch may be tricky, as if there are any
	st patches (102035) from the main OS release, you may have to
	backout this patch and install the other patches and reinstall this
	one.  This does not obsolete the 102035 patch, as this is not
	necessary for all customers, but it should contain all those fixes.

        As a point patch, this fix is not currently scheduled nor
        will necessarily be approved for integration in a future
        SunOS release.
