Installation
------------

To install this update:

1. Unzip the file into a new directory on the Firewall machine
2. Click on Start -> Settings -> Control Panel
3. Double click on the "Network" icon
4. Click on the "Protocols" tab at the top of the window
5. Click on "IBM Intermediate Support Driver" in the protocols list
6. Click on "Update"
7. A new window will appear which requests that you enter the path to the
   update files. Enter the name of the directory into which you unzipped
   the update file in step 1, followed immediately by a backslash ("\") and
   the National Language version which you require:

        German:              de_DE
        US English:          en_US
        Spanish:             es_ES
        French:              fr_FR
        Italian:             it_IT
        Japanese:            ja_JP
        Korean:              ko_KR
        Portuguese:          pt_BR
        Simplified Chinese:  zh_CN
        Traditional Chinese: zh_TW

   For example, if you unzipped the update into the directory d:\temp and
   you are using a German system, enter "d:\temp\de_DE" as the pathname.

   After you have entered the pathname, click on "Continue."

8. Click on "Close"
9. Permit the machine re-boot to occur


Problems with Certain Network Interface Card Drivers
----------------------------------------------------
Some problems have been found using the IBM Intermediate Support Driver
with older network interface card drivers. The following drivers are
known to have problems:

* Driver AMDPCN.SYS to control the onboard ethernet card in
  the IBM PC 325 and Netfinity servers. A miniport (NDIS 4.x)
  driver named PCNTN4M.SYS is available from AMD which replaces
  the older driver and works correctly with the IBM
  Intermediate Support Driver.

  PCNTN4M.SYS is one of AMD's "PCnet Family Software Drivers"
  and is currently available from:

  http://www.amd.com/products/npd/software/pcnet/objectcode/ver33.html

  The driver is part of the "Disk 2" package.

* Driver IBMENIIN.SYS which controls the Ethernet /A adapter
  for MCA.  This driver will not work and a newer driver for
  this network interface card is not available.

* Driver IBMEA351.SYS which controls the PCI Ethernet adapter.
  This driver is apparently in support of NT 3.51, is an old style
  full NIC driver (not a miniport driver), and no upgrade of the
  driver is available.

In general, the IBM Intermediate Support Driver works best with
network interface card drivers that use the miniport driver
functions available with NDIS 3.0 or later.  If you experience
problems with a particular network interface card after the IBM
Intermediate Support Driver is installed, check to see if a
miniport version of the network interface card driver is
available.  If a newer driver for the network interface card is
available, be sure to install it before attempting to isolate
networking problems.
