What is Support Level Supplement (SLS) ptf9051a,
The UnixWare 7.1.4 Maintenance Pack 2 Supplement?


Problem Fixed
-------------

  1.  Fixed non-synchronized assignments of controller number by both
      pdiunits and SDI layer causing overlapping and conflicting SDI unit
      numbers asigned to usb_msto, leading to problems while accessing
      USB floppy drive(s).

  2.  If after initiating shutdown, the system is not powered off after
      the following message is displayed, the processor heats up.
      "System has halted and may be powered off (Press any key to reboot)"

      fz530708

  3.  Fixed mps and atup PSM initialization to do "himem" detection
      after APIC & PIC initialization or after masking all interrupts on
      PIC, otherwise unexpected hardware interrupts can cause failure of
      v86bios() calls to detect "himem" via BIOS e820 interfaces leading
      to the OS not detecting the whole system memory.

  4.  Work around problem with IBM Blade Server (eserver 8677-1xx) BIOS
      version 1.09 that cause system panic shortly after boot.

  5.  Interrupts may be incorrectly routed when the ACPI boot
      parameter is set with "ACPI=Y".  It may also occur on uniprocessor
      systems that support hyperthreading and do not have MPS BIOS
      tables when the ENABLE_JT boot parameter is set with
      "ENABLE_JT=Y".  Most systems will not require this fix since the
      problem only manifests itself on systems with complex bus
      architectures.  Symptoms that the fix is required are any of:

      a) High CPU consumption in interrupt time when the system is
         otherwise idle, as indicated by sar and/or rtpm.

      b) Devices with interrupt timeouts.

      c) PCI devices that cannot be found.

  6.  The Boot Strap Processor is incorrectly identified on the Intel
      S3E31xx series (Harwich/Twin Castle) platform.  This problem
      manifests itself as a spontaneous system reset when the remaining
      processors are brought online.

      fz531694

  7.  Fixed a deadlock in asyc output stream.

  8.  Timeouts for bound drivers may run on wrong cpu.

      fz532326

  9.  Support to allow running global callout on any cpu. If this
      feature is enabled via setting callout_balance to 1 in svc.cf/Space.c,
      then callouts may execute on cpu other than the boot cpu. This has
      the affect of running callouts at the precise scheduled time in an
      heavy system workload.

Software Notes and Recommendations
----------------------------------

  ptf9051a should only be installed on:

  UnixWare 7.1.4 Maintenance Pack 2

o The Intel S3E31XX series (Harwich/Twin Castle) will not run in 
  multi-processor mode until ptf9051 is installed.  There are two
  work arounds.  Either defer OSMP installation during ISL until
  after ptf9051 is installed, or, interrupt the boot sequence during
  any reboots up until the time the ptf is installed, enter 
  "psm=atup" to boot into single processor mode.


Installation Instructions
-------------------------

  1. Download the ptf9051a.Z file to the /tmp directory on your machine.
     You can download the supplement from:

     ftp://ftp.sco.com/pub/unixware7/714/patches/

  2. As root, add the package to your system using these commands:

     $ su -
     Password: <type your root password>
     # zcat /tmp/ptf9051a.Z | pkgadd -d -

     Alternatively, this package may be installed in quiet mode, that is,
     without displaying the release notes and asking for confirmation.
     To do this, use these commands:

     $ su -
     Password: <type your root password>
     # zcat /tmp/ptf9051a.Z | pkgadd -qd - all

  3. Reboot the system after installing this package.


Removal Instructions
--------------------

  1. As root, remove the package using these commands:

     $ su -
     Password: <type your root password>
     # pkgrm ptf9051

  2. Reboot the system after removing this package.
