PRODUCT and VERSION:
UnixWare 1.1

ABSTRACT:

The ptf616 file contains UnixWare PTF616 patch for UnixWare 1.1.  
This update modifies the X server and kernel routines that deal 
with the keyboard and PS/2-style mice.  The modified routines will 
reset the mouse when switching display screens, preventing the mouse 
from displaying "wild" behavior (button pushes perceived as movement, 
movements perceived as button pushes).  The modified routines also 
prevent an occasional lock-up when zooming to a full screen from a 
desktop DOS window.

SYMPTOM

PS/2 type mouse goes "wild", window zoomed to full screen "locks-up"

SOLUTION

Solution Specifics

General Description
-------------------
These release notes acquaint you with the contents of the UnixWare 
PTF616 patch for UnixWare 1.1.  This update modifies the X server 
and kernel routines that deal with the keyboard and PS/2-style mice.  
The modified routines will reset the mouse when switching display 
screens, preventing the mouse from displaying "wild" behavior 
(button pushes perceived as movement, movements perceived as button 
pushes).  The modified routines also prevent an occasional lock-up 
when zooming to a full screen from a desktop DOS window.

New Features
------------
A statement was added to a kernel routine to reset the state of 
the PS-2 mouse when switching displays.  Display switches occur 
when zooming to full screen in DOS/Windows, or when a desktop user 
logs in from the text prompt on the console.  The keyboard routines 
were modified to prevent the machine from hanging when zooming to 
full screen DOS from a desktop DOS window.

Software Notes and Recommendations
----------------------------------
This update needs a system with the UnixWare 1.1 AS or PE with the update111
package installed.

NOTE: This patch is replaced by update 1.1.2


Hardware Notes and Recommendations
----------------------------------
None

Installation instructions
-------------------------
Place the diskette in the drive, and at the shell prompt type

     pkgadd -d diskette1

DO NOT use the desktop installation procedure.  After the package has been
successfully installed, reboot the machine by executing:

     cd /
     shutdown -i6 -y -g0

Troubleshooting
---------------
Try exiting the graphical login process (press Exit button) and logging 
in as a desktop user.  Make sure the mouse does not go "wild".  
Try this several times.  Also, try zooming from a desktop DOS window 
to a full-screen window.
