       Installing with Microsoft LAN Manager(tm) DOS Workstation for
                   HP 27247B PC LAN Adapter/16 TP Plus
                   HP 27252A PC LAN Adapter/16 TL Plus

This directory tree contains drivers and related files needed to install
the HP/16 Plus with Microsoft LAN Manager(tm) version 2.2 or earlier Basic
or Enhanced Workstation in a DOS or Windows computer.

Use the following instructions to install the HP/16 Plus and its DOS
NDIS 2.0.1 driver:

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.  Run the LAN Manager SETUP utility.

    Locate the Microsoft LAN Manager Installation and Configuration
    Guide and three Microsoft diskettes labeled "MS-DOS Setup", "MS-DOS
    Driver 1", and "MS-DOS Driver 2".  Insert the Microsoft diskette
    labeled "MS-DOS Setup" into the floppy drive.  For example, if the
    diskette is in drive A, then execute these DOS commands:

        A:
        SETUP

    After several screens of information, the SETUP utility will display
    a screen requesting (and supplying defaults) for the source and
    destination of the installation.  Follow the instructions on the
    screen to specify which DOS directory LAN Manager will install the
    files.  The default directory supplied will be C:\LANMAN.DOS.  Write
    down this directory in case changes to the PROTOCOL.INI file are
    required.  Press the ENTER key to select the installation paths.

    The SETUP utility will then prompt for selection of Basic or Enhanced
    Workstation, and proceed to load files from the "MS-DOS Setup" disk and
    the "MS-DOS Driver 1" disk.  The SETUP utility will now display the
    "Network Adapter Driver" window.


4.  Select the network adapter driver.

    To install the network adapter driver from the Microsoft diskette,
    follow the instructions under "Microsoft Diskette Installation".
    
    To install the network adapter driver from the HP Support Disk,
    follow the instructions under "HP Support Disk Installation".
    
    Microsoft Diskette Installation
    -------------------------------
        When the SETUP utility displays the "Network Adapter Drivers"
        list window, use the arrow keys to highlight the line:

            HP LAN Adapter/16+ TP or TL

        Press the ENTER key to accept the driver.
    
    HP Support Disk Installation
    ----------------------------
        When the SETUP utility displays the "Network Adapter Drivers"
        list window, use the TAB key to highlight the <Other Driver> menu
        choice at the bottom of the window.  Press the ENTER key.

        The SETUP utility next prompts for the network driver disk.  Insert
        the HP Support Disk into the floppy drive and press the ENTER key.
        After reading the HP Support Disk, the line:

            HP LAN Adapter/16+ TP or TL

        will be the only line appearing in the "Network Adapter Drivers"
        list window.  Press the ENTER key to select the driver.


5.  Select network protocols.

    After selecting the HP/16 Plus driver, the SETUP utility will display
    a "Network Protocols for HP LAN Adapter/16+ TP or TL" window.  Select
    the desired protocol(s) and continue with the installation.


6.  Complete the LAN Manager installation.

    Before the LAN Manager SETUP utility exits, it will advise that the
    PROTOCOL.INI file should be verified.  The HP/16 Plus DOS NDIS 2.0.1
    driver is self-configuring and does not require additional parameters.
    
    If more than one HP/16 Plus adapter is installed in the computer, the
    IOADDRESS parameter must be specified in the [HPLANP_NIF] section
    of the PROTOCOL.INI file.  See the note below labeled "PROTOCOL.INI
    Parameter Definitions" for descriptions of each PROTOCOL.INI parameter.


6.  The installation is finished.

    The installation and changes made will not take effect until the
    computer is rebooted.



PROTOCOL.INI Parameter Definitions
==================================

Below is an explanation of each PROTOCOL.INI parameter in the [HPLANP_NIF]
section for the HP 27247B or HP 27252A PC LAN Adapter/16 Plus.

The only parameter that must be present is the "DRIVERNAME".

If more than one HP/16 Plus is installed, the "IOADDRESS" parameter is
also required.

All parameters have default values.  A parameter need not be present in
PROTOCOL.INI if its default value is satisfactory.


DRIVERNAME
     units:[n/a]
     range:[HPLANP$, HPLANP2$, HPLANP3$, HPLANP4$]
     default:[HPLANP$]

   Identifies the LAN adapter driver.  Use a unique value from the range 
   indicated for each HP LAN adapter installed in your computer.  If you
   had two adapters installed, you would use HPLANP$ for the first adapter,
   and HPLANP2$ for the second.


INTERRUPT
     units:[integer]
     range:[3,4,5,6,7,9,10,11,12,15]
     default:[read from adapter, factory default 3]

   If present, it indicates which interrupt channel the driver should
   configure the adapter to generate interrupts.  The driver will override
   the interrupt channel configured by HPLANSET in step 2 until the computer
   is rebooted.


IOADDRESS
     units:[n/a]
     range:[0x100, 0x120, 0x140, 0x160, 0x180, 0x1A0, 0x1C0, 0x1E0
            0x200, 0x220, 0x240, 0x260, 0x280, 0x2A0, 0x2C0, 0x2E0]
            0x300, 0x320, 0x340, 0x360, 0x380, 0x3A0, 0x3C0, 0x3E0]
     default:[search all addresses]

   If present, indicates the base I/O address (ie. the first address in 
   HPLANSET I/o Address Range) configured on the adapter.  If the adapter is
   not at the base I/O address, the driver will exit with an error.
   
   If more than one HP/16 Plus adapter is installed in the computer, this
   parameter must be present under each HP/16 Plus NIF section.


MAXHWTRANS
     units:[integer]
     range:[2-20]
     default:[8]

   If present, this controls how the adapter memory is partitioned into
   into a transmit queue and a receive ring buffer.  The parameter value
   specifies the number of full-sized transmit packets that can be
   simultaneously stored in the adapter's transmit queue.  Each transmit
   packet consumes 1536 bytes.  The remaining adapter memory is used as a
   receive ring buffer.

   Both of the HP/16 Plus adapters (HP 27247B and HP 27252A) have 32 Kbytes
   (32K X 8) of memory.

   For example, if a HP/16 Plus were configured with MAXHWTRANS = 10, 
   15360 bytes would be allocated to the transmit queue and 17408 
   (32768 - 15360) would be allocated for the receive ring buffer.


MAXMULTICAST
     units:[integer]
     range:[1-50]
     default:[5]

   If present, this controls the maximum number of multicast addresses
   that can be simultaneously stored by the driver.  Each address consumes
   16 bytes of computer memory.


MAXSWTRANS
     units:[integer]
     range:[1-10]
     default:2

   Occasionally the HPLANP driver will put a transmit packet in a software
   queue before sending it to the adapter's transmit queue.  This parameter,
   if present, controls the number of packets that can simultaneously be
   stored in the software queue.  Each queue entry consumes 146 bytes of
   computer memory.


MAXICNEST
     units:[integer]
     range:[1-4]
     default:1

   If present, this controls the interrupt nesting depth of the driver.
   The value is the number of outstanding NDIS Indication Complete calls
   that the driver will allow.  When the limit is reached the driver
   will cease processing receive indications until an outstanding
   Indication Complete has returned.  Higher values will use greater
   amounts of stack space.


AUI
     units:[n/a]
     range:[YES,NO]
     default:n/a

   If present, this controls which of the adapter's LAN connectors is used.
   A value of 'YES' forces the 15-pin DIX (AUI) connector to be used. 
   A value of 'NO' forces the native LAN connector on the adapter to be used.  
   On the HP 27247B, the native connector is an RJ-45 twisted-pair connector.  
   On the HP 27252B the native connector is a BNC connector for thin LAN.
   The driver will override the LAN Connector configured by HPLANSET in step
   2 until the computer is rebooted.

   When this parameter is not present, the driver will use the value 
   configured on the adapter by the HPLANSET utility.  HPLANSET can specify
   automatic selection (the default), or identify a specific connector to
   be used.  Run HPLANSET to view or modify the HP/16 Plus's configuration.




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.
