	PHKL_20155:
	( SR: 8606107507 DTS: JAGab77743 )
	This patch enables new functionality, namely the SuperIO
	floppy drive interface, on B1000, C3000, and J5000
	workstations for HP-UX 11.00.

Defect Description:
	PHKL_21262:
	( SR: 8606117742 DTS: JAGac33047 )
	The open routine allows a class of bad dev numbers to be
	used.  If the dev number is for a device that doesn't exist
	or hasn't been claimed, then a NULL dereference can result.

	Resolution:
	The validation of the dev number was made more robust.

	PHKL_20155:
	( SR: 8606107507 DTS: JAGab77743 )
	This patch delivers new functionality to support SuperIO
	functionality on the B1000, C3000, and J5000 workstations
	as well as future HP-UX 11.00 workstations which support
	the SuperIO interface.  This patch provides the SuperIO
	Floppy functionality.

	The floppy drive on these systems can not be used unless
	this patch and the core SuperIO patch (PHKL_20152 or its
	superseding patch) is present.  However, if this patch
	is installed on your system without the core SuperIO
	patch also being installed, absolutely no change will
	occur to the system.

	Resolution:
	The objects necessary to support this function have been
	added to the kernel.

	------------------------------------------------------------
	1. Back up your system before installing a patch.

	2. Login as root.

	3. Copy the patch to the /tmp directory.

	4. Move to the /tmp directory and unshar the patch:

		cd /tmp
		sh PHKL_21262

	5. Run swinstall to install the patch:

		swinstall -x autoreboot=true -x patch_match_target=true \
			  -s /tmp/PHKL_21262.depot

	By default swinstall will archive the original software in 
	/var/adm/sw/save/PHKL_21262.  If you do not wish to retain a
	copy of the original software, use the patch_save_files option:

		swinstall -x autoreboot=true -x patch_match_target=true \
			  -x patch_save_files=false -s /tmp/PHKL_21262.depot

	WARNING: If patch_save_files is false when a patch is installed,
		 the patch cannot be deinstalled.  Please be careful
		 when using this feature.

	For future reference, the contents of the PHKL_21262.text file is 
	available in the product readme:

		swlist -l product -a readme -d @ /tmp/PHKL_21262.depot

	To put this patch on a magnetic tape and install from the
	tape drive, use the command:

		dd if=/tmp/PHKL_21262.depot of=/dev/rmt/0m bs=2k

Special Installation Instructions:
	In order for the SuperIO Floppy driver to function, the
	core SuperIO patch (PHKL_20152 or its superseding patch)
	must also be installed on the system.  The SuperIO Floppy
	driver is only required on the B1000, C3000, and J5000
	workstations, as well as future HP-UX 11.00 workstations
	which support the SuperIO interface.
