Dear SCO Customer,

Support Level Supplement (SLS) ptf7619c, the UnixWare 7.1.1 psm_apic Driver
Supplement and NSC 7.1.1+IP dependent node install supplement, addresses the 
following problems:

1.  On machines with an 8-way Intel Sabre motherboard, interrupts are not
    distributed to the eighth processor.

2.  Installation of UnixWare 7.1.1 hangs on systems with clock speed greater
    than or equal to 1Ghz.

3.  ptf7619b hangs some non 8-way systems.

4.  Support of UnixWare Non-Stop Clusters dependent node installation using the
    new Intel PRO/1000 F and PRO/1000 T Server Adapters.

5.  Support for network installation of Unixware 7.1.1 using PRO/1000 Adapters.

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

SLS ptf7619c should only be installed on:

        UnixWare 7 Release 7.1.1


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

For supporting systems with greater than 1GHz clock speed, new boot floppies
are provided.

      Cut the boot floppies and a Supplemental diskette:

      # dd if=ptf7619.new.boot.img1 of=/dev/rdsk/f03ht bs=32k
      # dd if=ptf7619.new.boot.img2 of=/dev/rdsk/f03ht bs=32k
      # uncompress ptf7619c.Z
      # dd if=ptf7619c of=/dev/rdsk/f03ht bs=32k <== Supplemental diskette

     Use the boot floppies to install the system. Near the end of the
     installation, you will be prompted for a ptf diskette. At this point,
     insert the Supplementary diskette in the floppy drive and choose
     "Install A PTF".

For updated support of network installation of Unixware 7.1.1 using
PRO/1000 Adapters, new netinstall floppies are provided. Please
check the README.ptf7619c for details.

NOTE: that ptf7619c itself isn't applicable and can't be installed on NSC
systems. So the 1Ghz support does not apply for NSC systems.

For support of UnixWare Non-Stop Clusters dependent node installation
using the the new Intel PRO/1000 F and PRO/1000 T Server Adapters,
new boot and netinstall images are provided. Please check the
README.ptf7619c for details.


1. Download the ptf7619c.Z file to the /tmp directory on your machine.

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

        $ su
        Password: <type your root password>
        # uncompress /tmp/ptf7619c.Z
        # pkgadd -d /tmp/ptf7619c
        # rm /tmp/ptf7619c


Alternatively, SLS ptf7619c may be installed in quiet mode, that is, without
displaying the release notes and asking for installation confirmation. To do
this, use these commands:

        $ su
        Password: <type your root password>
        # uncompress /tmp/ptf7619c.Z
        # pkgadd -qd /tmp/ptf7619c all
        # rm /tmp/ptf7619c

3. Reboot the system after installing this SLS package.

The release notes displayed prior to installation can be found in:

        /var/sadm/pkg/ptf7619/install/ptf7619.txt


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

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

        $ su
        Password: <type your root password>
        # pkgrm ptf7619

2. Reboot the system after removing this SLS package.


If you have questions regarding this SLS, or the product on which
it is installed, please contact your software supplier.
