                      Packet Driver Installation

EN2220PD.COM is the packet driver for the EN2220 CardBus PC Card.  Before
running EN2220PD.COM, please execute the EN2220 enabler, CBOPEN.EXE.

EN2220PD syntax:

EN2220PD  [-#] [-a] [-b] [-t] [-f] [-s] [-d] [-n] [-w] [-u] [-h] <PD_INT_NO>


[-#]           The "-#" option selects a specific EN2220 PC Card when 
               there are multiple EN2220 cards installed in the computer.  
               "-1" specifies the card in socket 0 which CBOPEN 
               enabled. "-2" specifies the card in socket 1 which CBOPEN

[-a]           The "-a" option tells the driver to perform automatic media
               detection during driver initialization.  

[-t]           The "-t" option tells the driver to use Twisted Pair (RJ-45)
               (10BASE-T) as the transmission media. 

[-f]           The "-f" option enables the FULL_DUPLEX feature of the card.
               It has effect only when Twisted Pair is used.

[-s]           The "-s" option sets the link speed to 100 Mbps.  

[-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 0x6F.

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


The following command line loads the Packet Driver at software interrupt 60h, 
and the transmission media is automatically detected.  The I/O base address
and the IRQ value are read from the CardBus card's configuration space.

EN2220PD -a 0x60  or EN2220PD 0x60

   1) The default transmission media is automatic-detection.

   2) The placement of 0x prior to the parameters indicates this is a 
      hexadecimal number.

How To Update Drivers Manually

After your driver has been downloaded, follow these simple steps to install it.

  • Expand the archive file (if the download file is in zip or rar format).

  • If the expanded file has an .exe extension, double click it and follow the installation instructions.

  • Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.

  • Find the device and model you want to update in the device list.

  • Double-click on it to open the Properties dialog box.

  • From the Properties dialog box, select the Driver tab.

  • Click the Update Driver button, then follow the instructions.

Very important: You must reboot your system to ensure that any driver updates have taken effect.
