(1) OVERVIEW
============


SKFM.OS2 is an OS/2 NDIS MAC driver which is intended to
operate with SK-NET FDDI MCA adapters on OS/2 v2.0, v2.1 and Warp 3.
You can install up to two adapters in an OS/2 station as long
as their settings do not conflict.

The driver complies to the NDIS specification v2.0.1.

This documentation gives useful hints on the installation and
configuration of this driver on IBM LAN Server 3.0 and 4.0.




(2) DRIVER INSTALLATION
=======================

The first step is the installation of the SK-NET FDDI MCA
adapter hardware in your workstation. For more information about
this installation and configuration, refer to the adapter's manual.

When the hardware installation is completed, boot your system.
Installing and configuring the driver software will be done by
using the Multi Protocol Transport Services (MPTS) if
IBM LAN Server 4.0 is installed or the LAN Adapter and
Protocol Support (LAPS) if IBM LAN Server 3.0 is installed.

Step 1) Start MPTS or LAPS on your system. The main menu will appear.

Step 2) Choose <Install>. The window <<Install Additional Network Drivers>>
	appears.

Step 3) Insert the Driver Installiation disk 3 into drive A:.

Step 3) The programm ask you to enter the path where the Network
	driver files reside on the driver installation disk. Type

			a:\lansrvr\os2

	and choose <ok> to confirm.

Step 4) The driver files will be copied to your hard disk.
	When the installation is finished the <<Installation
	Complete Screen>> appears. Choose ok to return to the
	main menu.


Now you have to configure the OS/2 NDIS MAC driver. Please
continue with chapter 3 "Driver Configuration".



(3) DRIVER CONFIGURATION
========================

Before the SK-NET FDDI MCA can be used, it must be configured
and bound to at least one protocol stack.

Step 1) From the main menu of MPTS or LAPS choose <Configure>.
	The configuration options will be displayed in the
	next screen.

Step 2) If the MPTS (LAN Server 4.0) utility is used, select
	<Configure LAN adapters and protocols> and press <Enter>.
	If the LAPS (LAN Server 3.0) utility is used, select
	<Configure LAN transports> and press <Enter>.
	The <<LAPS Configuration>> screen appears.

Step 3) Select the SK-NET FDDI MCA in the <<Network Adapter>>
	window and add it to the current configuration.
	For each protocol you want to work with, select
	it from the <<Protocol Window>> and add it to the
	<<Current Workstation Window>>.

Step 4) If you have installed more than one SK-NET FDDI MCA adapter
	in your workstation, you have to specify the parameter Slot Number.
	If you have only one adapter installed, the configuration is
	complete, please continue with step 5.

	o Select the SK-NET FDDI MCA adapter in the
	  <<Current Workstation>> window.
	o Choose the <Edit> option and update the required parameters.
	o To get the valid values or valid range for a parameter,
	  select the paramter and choose the <Range> option.
	o To get the online help for a parameter, select it and
	  press F1.
	o Choose <Ok> to confirm the changes.

	Parameter	Default Value	Accepted Values
	-----------------------------------------------
	Slot Number	    none	1 to 8

Step 5) Choose <Ok> to save the configuration and <Close> to come back
	to the main menu.
	Now choose <Exit> and leave the configuration utility.
	MPTS / LAPS will create a PROTOCOL.INI file and update your
	CONFIG.SYS to match the current configuration you just defined.

	Reboot your workstation to establish the changes.



(4) DRIVER PARAMETERS
=====================


Specifying or changing driver parameters should be done by using
the installation and configuration utilities MPTS or LAPS. This
tools will change the PROTOCOL.INI file (needed at system start
up) and/or the CONFIG.SYS file. Do not modify the PROTOCOL.INI
file with an editor. You may get configuration errors at boot time.

For specifying the driver parameters go to the <<LAPS Configuration>>
screen of MPTS / LAPS. Select the  SK-NET FDDI MCA adapter in
the <<Current Workstation>> window. Choose the <Edit> option and
update the necessary parameters.

You can get the valid range or valid values for each parameter, by
selecting the paramter and choosing the <Range> option.
To get the online help for a parameter, select it and press F1.



	(4.1) GENERAL DRIVER PARAMETERS


This section will give you a description of the driver parameters
supported by the OS/2 NDIS MAC driver.

This parameters are used to configure the SK-NET FDDI MCA adapter
hardware or the drivers interface to the NDIS protocol stack.

Network Adapter Address

Description:	 Overwrites the network adapter's node address
Help:	With this parameter, you can overwrite the default node address.
	In a network, every adapter must have its own and unique node
	address. A node address consists of 12 hexadecimal bytes.
	If the parameter Emulate Topology is set to 'TokenRing' you
	have to specify the node address in non-canonical format.
	If the parameter Emulate Topology is set to 'Ethernet' you
	have to specify the node address in canonical format.

NOTE:	Do not specify multicast or broadcast addresses for this parameter.
NOTE:	Do not assign the same local address to more than one adapter.
NOTE:	The Locally Administrated Bit of your specified node address should
	be set. This bit is in the first byte of the node address.
	It is bit 6 if the driver emulates Token-Ring and bit 1 if the
	driver emulates Ethernet.

Syntax: non-canonical format for emulating Token-Ring

	Network Adapter Address 	400005a02482C


Syntax: The same address but in canonical format for emulating Ethernet

	Network Adapter Address 	020005a401234


Slot Number

Description: Defines the slot in which the adapter is installed.
Help:	If you do not specify a slot number, the driver scans
	automatically for an SK-NET FDDI MCA adapter.
	The valid range for this parameter reaches from 1 to 8.
NOTE:	Specifying the parameter Slot Number is mandatory if more
	than one SK-NET FDDI MCA adapter is installed in the
	same computer.


Emulate Topology

Description: The type of network topology the driver currently emulates.
Help:	Because the FDDI topology is not implemented in the NDIS
	protocol stacks the driver has to emulate either Token-Ring
	or Ethernet. The default value for this parameter is
	'TokenRing'.
NOTE:	Emulating Ethernet may decrease the performance of the driver,
	because the driver is required to use the smaller Ethernet
	frame size of 1514 bytes instead of Token-Ring 4504 bytes.


IBM Source Routing Support

Description: Enables or disables the IBM Source Routing Support.
Help:	The possible values for this parameter are 'YES' and 'NO'.
	If the IBM Source Routing Support is set to 'NO', in all
	sent packets the IBM Source Routing field is cut by the
	driver. The default value is 'YES'.
NOTE:	Specifying this parameter has only an effect, if the
	parameter Emulate Topology is set to 'TokenRing'.


TCPIP on Token Ring Support

Description: Enables of disables the TCPIP on Token Ring Support.
Help:	The possible values for this parameter are 'YES' and 'NO'.
	If this parameter is set to 'YES', in all IP and ARP packets,
	the IBM Source Routing field is cut by the MAC driver and in
	all ARP packets the sender host address and the target host
	address are converted from non-canonical to canonical format
	during transmission.
	The sender host address and the target host address in a received
	ARP packet are converted from canonical to non-canonical format
	by the MAC driver, too.


Ring Status Mask

Description: The ring status delivered to the protocol driver is masked
	using the value of this parameter.
Help:	The OS/2 NDIS MAC driver indicates the ring status and ring errors
	to the NDIS protocol stack. With this paramter it is possible
	to fade out some indication bits. For more information about
	the ring status indication bits please refer to the IBM Token-Ring
	Technical Reference Manual.


	(4.2) ADVANCED DRIVER PARAMETERS

This section will give you a list of the advanced parameters established
in the OS/2 NDIS MAC driver. These parameters will give access to the
FDDI Station Management (SMT).

The SMT parameters are divided into three groups:

      - General SMT parameters
      - Synchronous Bandwith Allocator (SBA) parameters
	for configuring the SBA
      - End Station Support (ESS) parameters for using
	synchronous bandwidth

A detailed description of each parameter is given in the SMTDOCU.TXT
file in the root of this diskette. But this documentation uses the
short names for the SMT parameters. The following table holds the
supported SMT parameters and the corresponding short names.

General SMT parameters supported by this driver:


SMT parameter			SMT parameter short name
-------------------------------------------------------------------------
Password for PMF Requests		PmfPassWd
SMT User Data				UserData
SMT LER Cutoff attribut Port A		LerCutOffA
SMT LER Cutoff attribut Port B		LerCutOffB
SMT LER Alarm attribut Port A		LerAlarmA
SMT LER Alarm attribut Port B		LerAlarmB
SMT T-Min attribut			TMin
SMT T-Max attribut			TMax
SMT T-Req attribut			TReq
SMT TVX attribut			TVX
-------------------------------------------------------------------------


For the SBA and ESS parameters the short names are used in the MPTS / LAPS
configuration. Therefore a list and a short description for each supported
parameter follows.

SBA parameters supported by this driver:

Parameter	Short description
-------------------------------------------------------------------------
SbaCommand	command to start or stop the SBA
SbaAvailable	amount of bandwidth, the SBA can assign for
		synchrounous transmission
-------------------------------------------------------------------------


ESS parameters supported by this driver:

Parameter	Short description
-------------------------------------------------------------------------
SbaPayLoad	requested synchronous bandwidth for static allocation
SbaOverHead	requested overhead for static allocation
MaxTNeg 	maximum token rotation time delay
MinSegmentSize	minimum synchronous segmentation size
SbaCategory	session ID for the static allocation
SynchTxMode	synchronous transmission mode
-------------------------------------------------------------------------

(5) STARTUP ERROR MESSAGES
==========================


	(5.1) OVERVIEW


If an initialization error occurs at driver start up, the driver will
be unloaded by the system and this system message is displayed:

-------------------------------------------------------------------------
SYS1201: The device driver C:\IBMCOM\MACS\SKFM.OS2 specified
in the DEVICE command on line <line number> of the config.sys file
was not installed. Line <line number> is ignored.

Press Enter to continue
-------------------------------------------------------------------------


After <Enter> is pressed, the system continues to load the other
device drivers. After all device drivers are loaded the a separate
screen is opened and the error message generated by the OS/2 NDIS
MAC driver is displayed - for example

-------------------------------------------------------------------------
SKM0011: There is no SK FDDI adapter installed in this computer.
->Press Enter to continue
-------------------------------------------------------------------------

After pressing <Enter> some more error messages from other device drivers
may be printed out.

To get some more information about the error message open an OS/2 window
and type

Syntax: 	help <message number>


Example: To get help about the current error message please type

		help SKM0011





	(5.2) LIST OF ERROR MESSAGES


The following list holds the error messages that may occur on
SKFM.OS2 driver startup. If one of these errors occurs,
take a look at this description for error detection and problem fixing:



Message: There is no SK FDDI adapter installed in this computer.

Reason: The driver did not find an SK-NET FDDI MCA adapter which
	it was able to use. Perhaps you have specified a wrong
	Slot Number?
Help:	Check the hardware configuration (system configuration).
	Refer section (3) and (4) for hints about specifying the
	Slot Number.


Message: There is more than one SK FDDI adapter installed in
	 this computer.

Reason: The driver found more than one SK-NET FDDI MCA adapter
	during EISA or Micro Channel slot search. Thus, the driver
	could not decide which one to use actually.
Help:	Select one of the adapters by specifying a Slot Number.


Message: CFG_CARD_EN bit of the SK FDDI adapter is not set!

Reason: The SK-NET FDDI MCA adapter was not properly installed
	by the system configuration program. The present configuration
	of your adapter is void.
Help:	Restart the conifugration program and configure the adapter
	manually if necessary.

Message: Selected IRQ for the SK FDDI adapter is in use and
	 not sharable.

Reason: The configured hardware interrupt is already used by
	some other hardware. The OS/2 NDIS MAC driver cannot
	share an interrupt with some other drivers.
Help:	Run the system configuration program and select an other unused
	interrupt.


Message: The memory of the SK FDDI adapter exceeds 16 MByte.
	 Please use a 32 bit slot.

Reason: The driver has been loaded into a memory area beyond
	16 MBytes, while the adapter has been inserted in a 16-Bit
	Slot and thus cannot be addressed. Consequently, the
	adapter can not operate.
Help:	Install the adapter in a 32-Bit slot.


Message: The LAN Message Device Driver is not available.

Reason: The device driver for printing out device driver messages is
	not installed. If an initialization error occurs the error
	message of the driver will be printed directly to the screen.
Help:	Insert the following statement in the CONFIG.SYS file before
	the device driver PROTMAN.OS2 is loaded.
	C:\IBMCOM\LANMSGDD.OS2 /I:C:\IBMCOM


Message: The required parameter EMULATE was not found in the
	 PROTOCOL.INI file.

Reason: The parameter Emulate Topology was not specified in the
	driver configuration section. But this parameter is mandatory.
Help:	Start MPTS or LAPS and configure Emulate Topology either to
	'TokenRing' or to 'Ethernet'.


Message: The SK FDDI NDIS device driver could not open the
	 NDIS protocol manager.

Reason: An error occurred when the driver tried to open the protocol
	manager. Perhaps the protocol manager has not been loaded or
	the OS/2 NDIS MAC driver is loaded to early.
Help:	You have a serious problem with your LAN Server installation.
	Please delete the SKFM.OS2 statement in your
	CONFIG.SYS file. Start MPTS or LAPS and configure the driver
	again. Reboot the workstation.


Message: The SK FDDI NDIS device driver could not get the
	 protocol manager linkage.

Reason: An error occurred when the GetProtocolManagerLinkage function
	of the protocol manager was started.


Message: The SK FDDI NDIS device driver could not get the
	 protocol manager info.

Reason: An error occurred when the GetProtocolManagerInfo function of
	the protocol manager was started.


Message: The SK FDDI NDIS device driver could not register
	 with the protocol manager.

Reason: An error occurred when the RegisterModule function of the protocol
	manager was started.


Message: The ALT-Key was pressed. The loading of the SK FDDI
	 device driver is aborted

Reason: The loading process of the OS/2 NDIS MAC driver has been
	aborted by key strike. The device driver has not been loaded.



(6) KNOWN LIMITATIONS
=====================

Be careful when using the parameter 'Network Adapter Address', the driver
accepts also mulicast and broadcast addresses.
