I. The driver EN5251PD.COM can be used for the following:
   Accton EN5251 Based Fast Ethernet Adapters


EN5251PD          syntax:

EN5251PD          [-#] [-a] [-t] [-f] [-s] [-n] [-w] [-u] [-h] <PD_INT_NO>


Parameter       Explain
-----------------------------------------------------------------------------
[-#]            The "-#" option will let the driver work on a specific adapter
                when multiple EN5251 based adapters are found in the computer
                system.  For example, "-1" means the first adapter will be
                activated by the driver, "-2" means the second adapter will
                be activated, ... etc.

                A maximum of 4 adapters are supported simulaneously.

[-a]            The "-a" option will let driver perform automatic media
                detection during driver initialization.  The detection
                sequence is

                TP 100Mbps Full Duplex ---> TP 10Mbps Full Duplex --->
                TP 100Mbps Half Duplex ---> TP 10Mbps Half Duplex
                
                If no physical media is attached to the adapter then TP
                100Mbps Full Duplex is the default media.

[-t]            The "-t" option is to use Twisted Pair (RJ-45) (10BASE-T) as
                the transmission media. And it is also the default setting.

[-f]            The "-f" option enables FULL_DUPLEX feature of the adapters.
                It has no effect except when Twisted Pair is used.

[-s]            The "-s" option sets the adapter line speed to 100Mbps. It is
                a dedicated option for the EN5251 Based Ethernet adapter.

[-n]            Your NOVELL server uses NOVELL ISO-like packets. Your NOVELL
                workstation uses NOVELL 8137 packets. You can use this option
                to convert NOVELL 8137 packets into NOVELL ISO-like packets.

[-w]            Steve Wallace added a hack to let the packet drivers run under
                Windows. This is not to be construed with the proper solution,
                which is to write a TCP/IP package for Windows.

                This hack is enabled only when you use the '-w' switch.

[-u]            This option unloads the Packet Driver.

[-h]            This option displays the on-line help.

<PD_INT_NO>     This specifies the software interrupt (INT) where you'll load
                the packet driver. It must be in the range 0x60 to 0x80.

-----------------------------------------------------------------------------
Notice!!  The PC/TCP kernel, by default, is loaded at interrupt 0x61
          (so don't load the packet driver there!)

Example:

The following command line loads the
EN5251 based adapter Packet Driver at software interrupt 60h, transmission
media is automatical-detected:

                EN5251PD -a 0x60  or EN5251PD 0x60

** Note **
   The default transmission media is automatic-detection.
   The prefix of 0x to the parameters.
