Dear SCO Customer,

Support Level Supplement (SLS) PTF3288E, the 3Com 3C509 Driver Supplement, 
installs and configures a new driver that supports the 3Com 3C509 Etherlink 
III ISA Adapter.  SLS PTF3288E uses the Network Interface Card Support Utility
to dynamically load the 3Com driver (el3) from the Independent Hardware 
Vendor (IHV) Configuration diskette you create.


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

SLS PTF3288E should only be installed on these releases:

    SCO UnixWare Application Server Release 2.1.0, 2.1.1, 2.1.2, 2.1.3
    SCO UnixWare Personal Edition Release 2.1.0, 2.1.1, 2.1.2, 2.1.3


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

A diskette containing the new 3Com 3C509 Adapter driver (el3) in IHV format, 
for use with the UnixWare Network Interface Card Support Utility, is required.
To create the diskette and install and configure the driver, follow these 
steps:

1. Become root and create a new directory by typing the following:
 
     $ su
     Password: <type your root password>
     # mkdir /tmp/pkg
     # chmod 700 /tmp/pkg
     # cd /tmp/pkg

2. Create the IHV driver diskette:

   a. Download the ptf3288e.ihv.dd.Z file, which was packaged using dd(1M) and
      compress(1), and the ptf3288e.txt file to the /tmp/pkg directory on your
      system.

   b. Insert a high density diskette (not write-protected) into the A: drive.
      If the diskette is DOS-formatted, skip to the next step.  Otherwise,
      the diskette may be formatted (in the A: drive) using this command:

        # format -i 1 -E /dev/rdsk/f03ht

   c. Transfer the contents of ptf3288e.ihv.dd.Z to a DOS-formatted diskette
      using these commands:

        # uncompress /tmp/pkg/ptf3288e.ihv.dd.Z
        # dd if=/tmp/pkg/ptf3288e.ihv.dd of=/dev/rdsk/f03ht

3. Install and configure the driver.

   a. Invoke the NIC Support Utility.  The utility can be accessed from the
      Desktop GUI "Admin_Tools -> Networking -> NICS_Setup" icons, or from 
      the command line as "/usr/sbin/niccfg".  The utility provides a simple
      menu-oriented graphical interface with online help.

        # /usr/sbin/niccfg

   b. Select the "Install driver from IHV diskette" item from the niccfg 
      menu presented.

   c. Insert the IHV configuration diskette and press <Enter>.  
      The utility will now install and configure the driver (el3) 
      for the 3Com 3C509.

   d. Select the "Accept all entries" item from the menu presented. 
      The utility will dynamically load the el3 driver into the 
      UnixWare kernel.

4. Establish an Internet configuration for your system.

   a. The Internet setup required for your internet node can be established
      by using the utility access from the Desktop GUI "Admin_Tools ->
      Networking -> Internet_Setup" icons or the command line utility,
      "/etc/inet/menu".

5. Reboot the system.

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

We appreciate your business.
