DOS and OS/2 NDIS2 DRIVER FOR FAST ETHERNET PCI ADAPTER KF-221TX
================================================================
The NDIS2 DOS driver can be used for the following environments:
Artisoft's "LANtastic for DOS/Windows",
IBM LAN Service program
Microsoft Lan Manager 2.x
Windows for Workgroups Version 3.1
Windows for Workgroups Version 3.11
PATHWORKS for DOS Version 4.0
The NDIS2 OS/2 driver can be used for :
Microsoft LAN Manager 2.x for OS/2 .
IBM Lan Server 3.0 or 4.0 for OS/2 .
DRIVER FILE: \ndis.dos\dc21x4.dos
\ndis.os2\dc21x4.os2
DRIVER NAME: dc21x4$
DRIVER KEYWORDS: the driver defines several keywords for specifying certain
adapter configuration parameters. The keywords can be
specified in the system PROTOCOL.INI file.
The keywords are defined as below:
Keyword Description
---------- --------------------------------------------------------------
SLOT Specify the adapter instance in a PCI computer.
Not present : auto scan the first adapter
Valid values: 16 - 26 ( 16 is First adapter)
-------------------------------------------------------------------------
SIA_MODE = AUTOSENSE ; auto detect 100Mbps or 10Mbps connection and
; ignore DATA_RATE option
= TP ; twsited pair interface running in standard mode
= TP_FULL_DUPLEX ; twsietd pair interface running in full duplex
------------------------------------------------------------------------------
DATA_RATE = MB100 ; configure the adapter for 100Mbps operation
= MB10 ; configure the adapter for 10Mbps operation
------------------------------------------------------------------------------
Advanced Keywords :
------------------------------------------------------------------------------
TX_THRESHOLD = FP ; "Full packet" threshold, store and forward
= LW128 ; the smallest threshold
= LW256 ; even smaller
= LW512 ; smaller threshold
= LW1024 ; a threshold of almost one packet
Controls the transmit threshold of the device. A small
threshold may improve performance, however in some machines
it could cause many packets to be lost, and perhaps the
connection may fail. Refer to \technote.txt for more information.
------------------------------------------------------------------------------
NUM_TX_BUFFERS = 4 - 16 ; Specifies the number of transmit buffers the
; driver should use. Default is 8.
------------------------------------------------------------------------------
NUM_RX_BUFFERS = 4 - 16 ; Specifies the number of receive buffers the
; driver should use. Default is 12.
------------------------------------------------------------------------------
TURBO = ENABLED ; Controls whether host-to-PCI posting (HPPE) will
= DISABLED ; be disabled or enabled. This is relevant only if
; the system's host-to-PCI bridge is INTEL's 82424
; (CDC) or 82434 (PCMC) bridge.
; ENABLED - disable HPPE, may improve performance
; DISABLED - enable HPPE
; <absent> - leave system setting as they sre.
------------------------------------------------------------------------------
Note: 1. Summary of the keyword combinations:
SIA_MODE DATA_RATE --> Connector selected
--------------------------------------------------
AUTOSENSE not specified auto detect
AUTOSENSE MB100 auto detect
AUTOSENSE MB10 auto detect
TP MB100 100 Mbps
TP MB10 10 Mbps
TP not specified 100 Mbps
TP_FULL_DUPLEX not specified 100 Mbps
not specified not specified auto detect
If no active network connection is established,
2. If SIA_MODE=AUTOSENSE is specified in protocol.ini and no
active cable is connected during loading the driver, 10Mbps
operation will be the default. Make sure an active connection
is established before loading driver if "SIA_MODE=AUTOSENSE"
is specified.
Download Driver Pack
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.
