                   HP 27252A PC LAN Adapter/16 TL Plus

In general, the Crynwr Packet Drivers can be used with a large array of
commercial, shareware, and public domain networking software.  The Packet
Driver for the HP/16 Plus (HPPCLANP.COM) is supplied in this directory
along with other files explaining the use, applications, and copyright
considerations for Crynwr Packet Drivers.  Except for this file and
HPPCLANP.COM, the files in this directory are from the Crynwr Packet
Driver Distribution, version 10.

Installation and use of the HP/16 Plus with a Packet Driver and
networking application typically consists of the following steps:

    - Install and test the HP/16 Plus.
    - Install the networking application.
    - Configure the networking application to use a Packet Driver.
    - Copy HPPCLANP.COM from the HP Support Disk.
    - Run HPPCLANP.COM
    - Run the application.

To install the HP/16 Plus and its Crywnr packet driver, follow the
instructions below:

1.  Install the HP/16 Plus into the computer.

    If you are installing the HP/16 Plus in an EISA computer, run the
    computer's EISA configuration utility first before installing the
    HP/16 Plus.  See "Note for EISA Computers" at the end of this file
    for directions.

    Follow the HP/16 Plus Installation Guide and the computer documentation
    for the correct procedure to install an I/O adapter into the computer.
    Ensure that power has been disconnected from the computer before opening
    the computer's case.


2.  Configure and test the HP/16 Plus.

    Reconnect power to the computer and boot DOS.  Run the HP configurator
    on the HP Support Disk.  For example, if the Support Disk is in floppy
    drive A, execute the following commands at the DOS prompt:

        A:
        HPLANSET

    Select "Auto Configuration" to let HPLANSET choose available I/O
    Address Range, and Interrupt Channel values.  Write down these
    values for later use.

    NOTE: Auto configuration does not work if more than one HP/16 Plus is
          installed.  See the HP/16 Plus guide section "Configuring Multiple
          Adapters in the Same Computer" for the correct procedure.

    Select "Card Test" to verify the adapter.  After it passes, select
    "Save configuration to card" and then "Exit program".

    Connect the LAN cable to the HP/16 Plus.


3.  Install the networking product.

    Follow the installation documentation provided with the networking
    product to install the product on the computer.

    Ensure to select Packet Driver as the driver interface option.
    Typically, the choices are NDIS, Packet Driver, or Open Data-Link
    Interface (ODI).


4.  Copy the Packet Driver from the HP Support Disk.

    Create a directory on the computer.  For example,

        C:
        MKDIR \PKTDRV

    Copy the Packet Driver file from HP Support Disk this directory.
    For DOS computers with the HP Support Disk in floppy drive A:

        COPY A:\PKTDRV\HPPCLANP.COM C:\PKTDRV


5.  Run the Packet Driver.

    Typically, the HP/16 Plus Packet Driver needs only the software
    packet_int_no provided as a parameter.  For example, to run the
    packet driver using software interrupt 60 hex, enter the following
    command at the DOS prompt:

       C:\PKTDRV\HPPCLANP 0x60

    The complete instructions (which will be included in future versions
    of INSTALL.DOC) are:


          HP Adapter/16 Plus cards

              usage: hppclanp [-n] [-d] [-w] packet_int_no [io_addr]

               The hppclanp driver supports Adapter/16 Plus LAN cards
          based on the National 8390 chip.  Earlier HP LAN cards should
          use the hppclan driver.  The hppclanp driver uses one optional
          parameter -- the I/O address. If the I/O address is not given
          the Packet Driver searches for and finds the Adapter/16 Plus
          LAN card with the lowest I/O address in the PC.

    See the file INSTALL.DOC for further explanation.


6.  Run the networking application.

    The networking application may need to be supplied with the software
    interrupt number (0x60 in the example above), or it may search for
    installed Packet Drivers.  Consult the documentation for the
    networking application for instructions on how to start the
    application and supply the software interrupt number.




Note for EISA Computers
=======================
Run the EISA configuration utility supplied with the computer to select
values for the two HP/16 Plus resources:  I/O Address Range and Interrupt.
The EISA utility will ensure that resources allocated to the HP/16 Plus will
not be given to other adapters.

The EISA configuration files for the HP/16 Plus reside in the root directory
on the HP Support Disk.  Depending the EISA configuration utility supplied
with the computer there may be a prompt to insert a vendor diskette (the HP
Support Disk), or the configuration files may have to be copied to the
directory or floppy where the EISA configuration utility expects them.  

Below are directions for using the EISA utility to select resources for
the HP/16 Plus:

A.  Run the EISA configuration utility supplied with the computer.
    Follow the procedure to add a new card to the computer.


B.  Select the proper configuration from the selections displayed:

    !HWP1832.CFG  HP EtherTwist PC LAN Adapter/16 TP Plus (27247B)
    !HWP18A0.CFG  HP EtherTwist PC LAN Adapter/16 TL Plus (27252A)

    Note: If the HP/16 Plus selections are not displayed and the EISA
          configuration utility did not prompt for the vendor diskette
          (the HP Support Disk), exit the EISA configuration utility.
          Copy the HP EISA configuration files to the directory or
          diskette containing the EISA configuration utility.  For example,
          if the HP Support Disk is in drive A, execute the following
          command:

             COPY A:*.CFG
    
          Then restart the EISA configuration process from step A.


C.  Use the EISA utility to view the adapter configuration details.

    If the "I/O Address Range" is not "300-31Fh (Factory Default)",
    see "Note on Resolving I/O Address Range Conflicts" below.


D.  Configure Boot ROM Address, if needed.

    If a Boot ROM is to be installed on the adapter, select an address range
    from the choices presented under the "Boot ROM" parameter.  Write down
    the selction for use in step two.


E.  Save the configuration and turn off power to the computer when
    instructed by the EISA utility.

            +--------------------------------------------+
            | Continue with step one of the instructions |
            +--------------------------------------------+




Note on Resolving I/O Address Range Conflicts
=============================================
If any of the computer's adapters, including any other LAN adapters, are
using I/O addresses in the same I/O Address Range as the HP/16 Plus factory
default (300-31Fh), HPLANSET will not be able to find the HP/16 Plus.

There are two methods to complete the installation:
    1) Remove the adapter using I/O Address Range 300-31Fh.
       Install the HP/16 Plus and run HPLANSET.
       Use "Manual Configuration" to select another I/O Address Range.  
       Save the configuration to the HP/16 Plus.
       Reinstall the conflicting adapter.
or,
   2)  Install the HP/16 Plus in another computer and run HPLANSET.
       Use "Manual Configuration" to select another I/O Address Range.  
       Save the configuration to the HP/16 Plus.
       Remove the HP/16 Plus from the computer.
       Install the HP/16 Plus in the original computer.
