Patch Description: s700 10.20 PS/2 mouse syncronization for 744/165L patch

Post Date:  97/11/17

Hardware Platforms - OS Releases:
	s700: 10.20

Products: N/A

Filesets:

Automatic Reboot?: Yes

Status: General Superseded

Critical: No

Path Name: /hp-ux_patches/s700/10.X/PHKL_12841

Symptoms:
	PHKL_12841:
	SR# 4701374082 DTS# DSDe440147: the mouse looses synchro-
	nization such that the pointer moves all over the screen
	and button presses are active that the user did not
	initiate.

Defect Description:
	PHKL_12841:
	SR# 4701374082 DTS# DSDe440147: the 744/165L has some
	signal integrity problems that caused long sequences of
	parity errors on the PS/2 bus. The driver did not account
	for these long sequences, thus a RESEND command from the
	mouse would be interpretted as a data byte, throwing off
	the synchronization of mouse packets. The keyboard did
	not show any symptoms of the long parity error sequences.
	Therefore, this fix only addresses the mouse
	synchronization problem.

Installation Instructions:

	------------------------------------------------------------
	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_12841

	5a. For a standalone system, run swinstall to install the
	    patch:

		swinstall -x autoreboot=true -x match_target=true \
			-s /tmp/PHKL_12841.depot

	5b. For a homogeneous NFS Diskless cluster run swcluster on the
	    server to install the patch on the server and the clients:

		swcluster -i -b

	    This will invoke swcluster in the interactive mode and
	    force all clients to be shut down.

	    WARNING: All cluster clients must be shut down prior to the
		     patch installation.  Installing the patch while the
		     clients are booted is unsupported and can lead to
		     serious problems.

	    The swcluster command will invoke an swinstall session in which
	    you must specify:

		alternate root path  -  default is /export/shared_root/OS_700
		source depot path    -  /tmp/PHKL_12841.depot

	    To complete the installation, select the patch by choosing
	    "Actions -> Match What Target Has" and then "Actions -> Install"
	    from the Menubar.

	5c. For a heterogeneous NFS Diskless cluster:

		- run swinstall on the server as in step 5a to install
		  the patch on the cluster server.

		- run swcluster on the server as in step 5b to install
		  the patch on the cluster clients.

	By default swinstall will archive the original software in
	/var/adm/sw/patch/PHKL_12841.  If you do not wish to retain a
	copy of the original software, you can create an empty file
	named /var/adm/sw/patch/PATCH_NOSAVE.

	Warning: If this file exists when a patch is installed, the
	         patch cannot be deinstalled.  Please be careful
		 when using this feature.

	It is recommended that you move the PHKL_12841.text file to
	/var/adm/sw/patch for future reference.

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

		dd if=/tmp/PHKL_12841.depot of=/dev/rmt/0m bs=2k
