T1108 LAN Support Program (LSP) driver installation for IBM NOSs other
than PC 3270
---------------------------------------------------------------------
Installing TR2KASI for IBM LAN Server
---------------------------------------------------------------------
1. To install the device driver, replace DXMA0MOD.SYS and
DXMC0MOD.SYS in the CONFIG.SYS file with TR2KA0.SYS and
TR2KASI.SYS, respectively.
2. To configure the device driver, there are command line
options that can be specified in the CONFIG.SYS file.
The format for specifying the options is as follows:
DEVICE=TR2KA0.SYS
DEVICE=TR2KASI.SYS [NODE ADDRESS] [PORT ADDRESS] [INT]
[SPEED] [BIT16] [WS0] [AIB]
Brackets [] are used to indicate optional parameters.
3. Copy the TR2KLLC.COD file to the root directory of the
drive where TR2KASI.SYS is located.

Parameters Supported by TR2KASI
---------------------------------------------------------------------
+--------------------------------------------------------------+
| Parameter | Range | Default |
+--------------------+------------------------------+----------+
| NODE ADDRESS | "000000000000"-"7FFFFFFFFFFF"| BIA |
| PORT ADDRESS | See description. | 0xA20 |
| INT | 2 - 12 | 2 |
| SPEED | 4 or 16 | 16 |
| BIT16 | See description. | - |
| WS0 | See description. | - |
| BUFFER SIZE | 256 - 17960 | 4216 |
| AIB | See description. | ROM |
+--------------------------------------------------------------+
NODE ADDRESS If the NODE ADDRESS parameter is specified, it must
be the first parameter on the line. All other
parameters may occur in any order. All parameters
except NODE ADDRESS, are preceded by a "/".
NODE ADDRESS is used to specify a 12 character node
address to be used in place of the burned in address
(BIA). The address MUST be a 12 digit hexadecimal
number in the range of 000000000000 to 7FFFFFFFFFFF.
If this parameter is omitted then the adapter BIA
address will be used.
PORT ADDRESS PORT ADDRESS is used to indicate the port I/O address
of the installed adapter. To select a specific I/O
PORT ADDRESS, use the /PORT=xxxx option, where xxxx
is a valid 4 digit hexadecimal address. If the /PORT=
option is omitted, the default PORT ADDRESS is A20.
***** NOTE: The PORT ADDRESS MUST be 4 digits. Leading zeros MUST
be present (i.e. /PORT=0A40).
INT The INT option is used to specify which interrupt (IRQ)
is being used to communicate to the adapter. INT 2 is
the default if the INT parameter is not specified. To
override the default, select the /INT=xx option, where
xx is a one or two digit decimal value indicating the
valid INT selected for the Token Ring adapter.
SPEED The SPEED parameter may be used to software select a
ring speed of 4 Mbps. The adapter will default to 16
Mbps or to the speed as defined by appropriate hardware
switches if the software can not override these
switches.
The syntax for this option is /SPEED=4.
BIT16 The BIT16 parameter is used to select 16 bit pseudo DMA
transfers to/from the base PORT ADDRESS plus 0x10.
Pseudo DMA defaults to 8 bit mode to/from the base PORT
ADDRESS.
To select 16 bit mode, specify the /BIT16 option.
WS0 The WS0 parameter tells the driver to select 8 bit
pseudo DMA transfers to/from the base PORT ADDRESS plus
0x10. This allows adapters designed to support this
feature to perform zero wait-state I/O's. To select
zero wait-state 8 bit mode, specify the /WS0 option.
BUFFER SIZE BUFFER SIZE can be used to select any receive buffer
size up to 18000 bytes. Default BUFFER SIZE is 4216
bytes. To set the BUFFER SIZE, include the /BUF=
parameter followed by the number of bytes to allocate
for the receive buffer. For example, /BUF=2048 would
set the receive buffer size to 2K.
***** WARNING: Do not configure your network to generate frames that
exceed the maximum receive buffer size.
AIB AIB is used to install a 256 byte block of data in base
system memory to provide adapter information to 3270
communications programs. This is needed for Token Ring
adapters which have no onboard ROM, or which have
ROM disabled. If the /MEM=xxx option is used, the /AIB
option is ignored. If used on PS/2 type systems with an
extended BIOS data segment at 639K, an additional 7.2
KBytes may be allocated to align to an 8K boundary.

Installing TR2KASI for a Token Ring LAN Adapter
---------------------------------------------------------------------
To install TR2KASI.SYS for use with NETBIOS, replace DXMC0MOD.SYS
with TR2KASI.SYS in the CONFIG.SYS file and include any desired
parameters. Make sure that TR2KLLC.COD resides in the root
directory of the drive where TR2KASI.SYS is located. Some
examples are provided below:
Example 1.
DEVICE=TR2KA0.SYS
DEVICE=TR2KASI.SYS
DEVICE=DXMT0MOD.SYS
Example 2.
DEVICE=TR2KA0.SYS
DEVICE=TR2KASI.SYS /PORT=0A40 /BIT16
DEVICE=DXMT0MOD.SYS
Example 3.
DEVICE=TR2KA0.SYS
DEVICE=TR2KASI.SYS /PORT=0A40 /BUF=16384
DEVICE=DXMT0MOD.SYS
Example 4.
DEVICE=TR2KA0.SYS
DEVICE=TR2KASI.SYS 400000001111 /SPEED=4 /BUF=1100
DEVICE=DXMT0MOD.SYS
Example 1 loads TR2KASI.SYS with the default parameters: the node
address is determined by the adapter BIA, the adapter speed is 16 Mbps
, the port address is A20, and pseudo DMA is enabled. The buffer size
will be 4K.
Example 2 installs the adapter with a port address of A40. The adapter
will use its adapter BIA for the node address. The adapter will
perform data transfers in 16 bit pseudo DMA mode. The receive buffer
size for both adapters is set to 4K bytes.
Example 3 installs the adapter with a port address of 0A40.
The receive buffer size is set to the 16K.
Example 4 installs the adapter with a node address of 400000001111.
Pseudo DMA is enabled for the adapter, and the buffer size will be
1100 bytes. The adapter will software select a ring speed of 4 Mbps.
If NETBIOS is not needed, omit the DXMT0MOD.SYS line. The LLC code
required by the T1108 adapter resides in a file called TR2KLLC.COD.
This file must be available in the root directory for TR2KASI.SYS to
read during load time.
***** NOTE: Unpredictable results will occur if hardware capabilities
or jumper selections do not match those selected by the parameter
or default values.
