*******************************************
* PACKET DRIVER PROGRAM FOR 3Com 3+ Share *
*******************************************

The INFOTEL 3Com 3+ Share Driver Program lets you run 3Com 3+ Share
on your PC with the INFOTEL IN-220P SERIES Ethernet card.

The following files will be used in this installation:

Files          Contents
-----------   -------------------------------------------------------
IN220P.SYS     Packet driver program for IN-220P SERIES card
ETH.SYS        3Com 3+ Share driver program


1. Follow the installation procedure for 3Com EtherLink board.

2. Copy the program ETH.SYS from the Installation Diskette for
   the INFOTEL IN-220P SERIES 16-Bit Ethernet card to the boot
   disk/diskette.
   This program will replace the program of the same file name
   (ETH.SYS) when you perform the installation procedure  in
   step 1  above.

3. In the CONFIG.SYS file on the boot disk/diskette, make sure
   you have the following two statements.  The order of these
   two statement must be as shown below.

     DEVICE = IN220P.SYS <-d> <packet_int_no> <-w>
     DEVICE = ETH.SYS

You may now boot and start your 3COM workstation.

*****************************************************
* PACKET DRIVER PROGRAM FOR Sun MicroSystems PC-NFS *
*****************************************************

The INFOTEL PC-NFS Driver Program lets you run Sun MicroSystems PC-NFS
on your PC with the INFOTEL IN-220P SERIES 16-Bit Ethernet Card.

The following files will be used in this installation:

Files           Contents
-----------     ----------------------------------------------------------
PDNFS.SYS       PC-NFS Driver Program
IN220P.SYS      Packet driver program for IN-220P SERIES card
IN220P.COM      Packet driver program for IN-220P SERIES card

Two methods can be used to install:

METHOD 1:

1. Install the PC-NFS program according to the procedure described in the
   PC-NFS manual.  On the screen of the PC-NFS install program, select 3C501
   (the 3Com EtherLink card) as your network interface card. When the screens
   prompt you, select 3 for the interrupt level (IRQ), and select 300h for
   the base I/O address.

2. Copy the following files to the \NFS directory of your hard disk:

     PDNFS.SYS
     IN220P.SYS
     IN220P.COM

3. Modify the CONFIG.SYS file as follows:

   DEVICE=C:\ANSI.SYS
   DEVICE=C:\NFS\PCNFS.SYS /m
   DEVICE=C:\NFS\SOCKDRV.SYS
   DEVICE=C:\NFS\IN220P.SYS <-d> <packet_int_no> <-w>
   DEVICE=C:\NFS\PDNFS.SYS
   LASTDRIVE=V

     AUTOEXEC.BAT file:

     SET PATH = C:\; C:\NFS
     SET TZ=EST5EDT
     NET YPDOMAIN ypserver
     NET START RDR
     NET YPSET homer
     NET NAME john
     NET USER F: \\user\john

       We use the name "john" here as an example.

4. Reboot the PC to start PC-NFS.

You may now execute the PC-NFS commands to communicate
other computers through the TCP/IP protocol.


METHOD 2:

1. Install the PC-NFS program according to the procedure described in the
   PC-NFS manual.  On the screen of the PC-NFS install program, select 3C501
   (the 3Com EtherLink card) as your network interface card. When the screens
   prompt you, select 3 for the interrupt level (IRQ), and select 300h for
   the base I/O address.

2. Copy the following files to the \NFS directory of your hard
   disk:

     PDNFS.SYS
     IN220P.SYS
     IN220P.COM

3. Modify the CONFIG.SYS file as follows:

        DEVICE=C:\ANSI.SYS
        DEVICE=C:\NFS\PCNFS.SYS /m
        DEVICE=C:\NFS\SOCKDRV.SYS
        DEVICE=C:\NFS\PDNFS.SYS
        LASTDRIVE=V

     AUTOEXEC.BAT file:

        SET PATH = C:\; C:\NFS
        SET TZ=EST5EDT
        IN220P <-d> <packet_int_no> <-w>
        NET YPDOMAIN ypserver
        NET START RDR
        NET YPSET homer
        NET NAME john
        NET USER F: \\user\john

       We use the name "john" here as an example.

4. Reboot the PC to start PC-NFS.

You may now execute the PC-NFS commands to communicate
other computers through the TCP/IP protocol.

****************************************
* PACKET DRIVER PROGRAM FOR FTP PC/TCP *
****************************************
The INFOTEL packet driver programs above let you run FTP's PC/TCP
with the INFOTEL IN-220P SERIES Ethernet Card.  Two methods can be used:

METHOD 1:

If you use the IN220P.SYS program, the following statement must
be included in your CONFIG.SYS file:

     DEVICE = IN220P.SYS <-d> <packet_int_no> <-w>

This statement may be placed anywhere in the CONFIG.SYS file.

METHOD 2:

If you use the IN220P.COM program, follow the procedure below:

1. Execute the IN220P.COM as follows:

     >IN220P <-d> <packet_int_no> <-w>

2. Execute the ETHDRV.EXE device driver program (provided by FTP).

You are now ready to use FTP's PC/TCP.

Notes:

<packet_int_no> is the software interrupt vector number used by the
                packet driver program, which can be from 96 to 128.
<-d>            Delay Initial - The driver program will not initialize
                the network interface card until the packet driver program
                is accessed by its upper layer program first time.
<-w>            the -w parameter is for use with the Windows environment only.
