[ Notice ]

The LAN driver software in this diskette is of beta version, and not yet
certified by 3Com corporation.  The first version of the driver software
will be released after the successful completion of the certification by
3Com corporation.

[ The 3Plus Driver ]

This diskette contains Toshiba Ethernet card driver for use with 3Com's
3Plus network operation system. The driver software file name is TSBETH.SYS.
The TSBETH.SYS is a MS-DOS device driver, and installed at boot time
according to the command line specified in the CONFIG.SYS file. 
This short document describes the overview of Toshiba LAN cards and how to
install this driver software in your workstation.


[ Toshiba LAN Cards ]

There are three versions of the Toshiba LAN cards.  Each supports both
of standard (thick) and thin Ethernet.  The cards are:

Type 1. Externally-powered Toshiba size card
        with an AC adapter
        without an AC adapter
Type 2. IBM XT compatible card
Type 3. Internally-powered Toshiba size card

This table identifies which card to use for each personal computer:


Computer    Type 1    Type 2    Type 3
----------------------------------------
T1200       yes
T1600       yes
T3100       yes
T3100/20    yes
T3100e                yes       yes 
T3200                 yes
T5100       yes
T5200                 yes       yes
T8500                 yes       yes


Before you insert the adapter in your PC, set the swithes and the jumper
settings on the interface card properly.  The default I/O base address is
280H and the default interrupt request (IRQ) level is 9.  More detail
information is described in the Toshiba LAN Installation Manual.


[ Installing the Driver Software ]

After installing the 3Com/3Plus network software as specified in the 3Com
Installation and Configuration Guide, copy the Toshiba Ethernet driver file
TSBETH.SYS from this diskette to the \3DRIVERS directory with new name
called ETH.SYS as below: 

CD C:\3DRIVERS
COPY  A:TSBETH.SYS  C:ETH.SYS

If you changed the I/O address and IRQ level, you also must to modify
the DEVICE=\3DRIVERS\ETH.SYS command line in your CONFIG.SYS file to reflect
them.  And if you want to change the default shared memory address and size
(32Kbytes from C800:0), you need to modify above command line. Use the format:

DEVICE = \3DRIVERS\ETH.SYS  IRQ-Level I/O-Base Memory-Base Memory-Size

where, 

IRQ-Level   : IRQ level of Toshiba LAN card (in decimal), default is 9.
              This number must be same with the jumper setting on the card.
I/O-Base    : I/O base address (in hexadecimal), default is 280.
              This number must be same with the jumper setting on the card.
Memory-Base : Shared memory base segment address (in hexadecimal), default 
              is C800.  You must select Memory-Base not to conflict to other
              ROMs, RAMs (esspecailly EMS).
Memory-Size : Shared memory size (in decimal, unit is KB), default is 32.       
              Memory-Size must be one of 64, 32, 16 (KB), and the larger size
              selection gives the higher availablity.
              Note that memory area must not across the 64K boundary.
  
For example, if you change IRQ to 3, I/O Base Address to 300H, Memory Base
Address to D000:0, and Memory Size to 64KB, device statement line should be:        
                                
DEVICE = \3DRIVERS\ETH.SYS  3 300 D000  64
