NDIS Driver Installation Overview
                       For Ethernet PCMCIA Adapter

The drivers contained in the directory MSLANMAN.DOS , and NDIS are
for use with  Ethernet PCMCIA adapter.

They are used with Com's 3+Open, Microsoft's OS/2 LAN Manager OEM,
distribution packages Release 1.x or 2.x,  and other compatible OEM
versions of LAN Manager.  The drivers named "ETHPCM"  conform to
the Network Driver Interface Specification (NDIS) defined by
Microsoft/3Com.

1. Installation Procedure

   Proper installation can be verified by running the
   diagnostic program CARDTEST.EXE in \DIAG directory under DOS.


2. Sample protocol.ini file and parameters

[ACCNE_NIF]

;  Default section of protocol.ini file for the Adapter

    drivername = ETHPCM$
    irq = 5
    iobase = 0x300

; End of this sample file

Several parameters are included in the ACCNE_NIF section of the
PROTOCOL.INI file.  However, the only parameter that must
be specified is the "drivername".  The other parameters use the
values detected by the driver.

irq         Specifies the interrupt channel used by the adapter.
            Acceptable values for this parameter are 2, 3, 4, 5,
            10, 11, 12 ,and 15. However, some of the mentioned
            adapters do not support all the acceptable values.


iobase      Specifies the iobase address used by the adapter.
            This parameter is given in hexadecimal values.
            Acceptable value for this parameter are 0x240, 0x280,
            0x2C0, 0x300, 0x320, 0x340, 0x360.


3. Additional Parameters in the protocol.ini file for
the NDIS Driver Configuration

  Keyword            Parameter

MaxMultiCast  1 .. 1000  Default 10
              Maximum number of MultiCast Addresses.
              This configures the size of the MultiCast
              Address Table.


MaxRequests   6 .. 64  Default 8
              Maximum number of outstanding General Requests.
              This configures the size of the General Request
              Queue.


MaxTransmits  6 .. 64  Default 12
              Maximum number of outstanding TransmitChain commands.
              This configures the size of the TransmitChain Request
              Queue.


ReceiveChains 6 .. 96  Default 12
              Maximum number of outstanding ReceiveChain commands.
              This configures the size of the ReceiveChain Request
              Queue.


ReceiveBuffers6 .. 96  Default 12
              Configures the number of the Receive buffers in the
              Receive Buffer Pool.

TROUBLE SHOOTING and ERROR MESSAGES

    If you have a problem, run "CARDTEST" program to determine if
    any parameters are in conflict.

ERROR MESSAGE:

    ERROR: Adapter card not found or I/O port error.

    There are two possible reasons for this error:
    (1) The Adapter card is not installed correctly in its slot,
    (2) The I/O port failure is caused by an incompatability between
    the computer and the adapter.


    ERROR: Incorrect Media Setting or Bad Tranceiver

    The following are the possible reasons for this error:  (1) The tranceiver
    is bad.  (2) The cable is broken. (3) The cabling is not attached.

    Please run the CARDTEST program to determine the reason for the error.
