Dear SCO Customer,

Support Level Supplement (SLS) ptf4018c, the 3Com 3C90x Driver Supplement,
installs and configures a new driver that supports the 3Com 3C90x EtherLink
XL PCI Adapter.  SLS ptf4018c uses the Network Interface Card Support
Utility to dynamically load the 3Com driver (e3H) from the Independent
Hardware Vendor (IHV) Configuration diskette you create.

SLS ptf4018c is identical to SLS ptf4018b with additional support for the
3Com EtherLink XL PCI (3C900B). 

SLS ptf4018b is identical to SLS ptf4018a with the addition of a fix
to force the PCI Bus Master bit to "on" so that the driver will work
with certain older system BIOSes.

SLS ptf4018c should only be installed on:

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

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

SLS ptf4018c can be installed using the pkgadd command or by creating an
IHV diskette from the supplied IHV image.  Follow the instructions provided
below, depending on the format you choose to load.


Installation using the pkgadd command:
--------------------------------------

1. Download the ptf4018c.Z file to the /tmp directory on your machine.

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

        $ su
        Password:
        # uncompress /tmp/ptf4018c.Z
        # pkgadd -d /tmp/ptf4018c
        # rm /tmp/ptf4018c

3. 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 "Accept all entries" item from the menu presented.  The
      utility will dynamically load the 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. Shut down and reboot the system after installing this SLS.

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

        /var/sadm/pkg/ptf4018/install/ptf4018.txt.

Installation of IHV format Supplement:
--------------------------------------

A diskette containing the 3Com 3C90x Driver 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, take these
steps:

1. Become root and create a new directory by typing:

        $ su
        Password:
        # mkdir /tmp/pkg
        # chmod 700 /tmp/pkg
        # cd /tmp/pkg

2. Create the IHV driver diskette:

   a. Download the ptf4018c.ihv.dd.Z file, which was packaged using dd(1M)
      and compress(1), and the ptf4018c.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 ptf4018c.ihv.dd.Z to a formatted diskette
      using these commands:

        # uncompress /tmp/pkg/ptf4018c.ihv.dd.Z
        # dd if=/tmp/pkg/ptf4018c.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 .  The utility
      will now install and configure the driver.

   d. Select the "Accept all entries" item from the menu presented.

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. Shut down and reboot the system after installing this SLS.
