***
(5) DRIVER OPTIONS
==================
The SK98WIN.SYS driver allows you to modify several options
in order to optimize the operation of your
SysKonnect SK-NET Gigabit Ethernet Adapter SK-984x.
The driver options can be set as follows:
Step 1.
Start NETWORK from the CONTROL PANEL, choose ADAPTERS, select
the SysKonnect SK-NET Gigabit Ethernet Adapter SK-984x and click
PROPERTIES.
Step 2.
In the SysKonnect SK-NET Gigabit Ethernet Adapter SK-984x Card Setup
window, select the option that you want to change and enter the desired
value.
Step 3.
Press OK when finished.
Step 4.
Reboot the machine.
**************************************************************************
NOTE:
The machine must be rebooted before any changed options can take effect.
**************************************************************************
The parameters supported by the driver are described below.
The Windows NT Installation Support provides an online help utility, which
describes all available parameter options in detail.
Bus / Slot
----------
Default value: next available adapter found when driver installed
Valid range: depends on system configuration
This parameter specifies the adapter instance to which the driver shall be
bound. You can choose from a list of bus/slot combinations for which the
system has found one or more instances of the
SysKonnect SK-NET Gigabit Ethernet Adapter SK-984x. When you add, remove,
or move any adapters to, from, or between PCI slots, this list will
change.
Preferred Port
--------------
Default value: "A"
Valid range: "A" or "B"
NOTE: This parameter is only available for the
SysKonnect SK-NET Gigabit Ethernet Adapter SK-984x dual link.
Use this parameter to set the preferred port that the RLMT (Redundant
Link Management) will use for all network traffic, if more than one port
has an active link to the network.
RLMT Mode
---------
Default value: "Check link state only"
Valid range: "Check link state only"
"Check other port"
"Check other port and segmentation"
NOTE: This parameter is only available for the
SysKonnect SK-NET Gigabit Ethernet Adapter SK-984x dual link.
Use this parameter to set the operational mode for the RLMT (Redundant
Link Management) built into the driver:
- "Check link state only": RLMT uses the link state reported by the
adapter hardware for each individual port to determine whether a port can
be used for all network traffic or not.
- "Check other port": RLMT sends test frames from each port to each other
port and checks if they are received by the other port, respectively.
Thus, the ports must be connected to the network such that LLC test frames
can be exchanged between them (i.e. there must be no routers between the
ports).
- "Check other port and segmentation": RLMT checks the other port and in
addition requests information from the Gigabit Ethernet switch next to
each port to see if the network is segmented between the ports. Thus, this
mode is only to be used if you have Gigabit Ethernet switches installed in
your network that have been configured to use the Spanning Tree protocol.
NOTE: RLMT modes "Check other port" and "Check other Port and
segmentation" are are meant to operate in configurations where a network
path between the ports on one adapter exists. Especially, they are not
designed to work where adapters are connected back-to-back.
Network Address
---------------
Default value: burned-in adapter address
Valid range: 0y-00-00-00-00-01 to FE-FF-FF-FF-FF-FF (hexadecimal), where
at least the "locally administered" bit 2h (i.e. bit #1) in
the 'y' nibble must be set and the "multicast" bit 1h (i.e.
bit #0) must not be set
CAUTION: Each individual network MAC address can only be used once in a
network. Assigning the same address to more than one adapter in the same
network is a fault and can cause serious network problems.
To use a network MAC address other than the one burned into the adapter
card, enter the network address in hexadecimal, in the following format:
XX-XX-XX-XX-XX-XX (e.g. 02-00-5A-98-12-34).
If you leave the Network Address blank (or specify a different number of
digits), the network address burned into the adapter card will be used.
MaxFrameSize
------------
Default value: 1514 (decimal)
Valid range: 14..1514 (decimal)
This parameter specifies the maximum frame size in bytes that the driver
will support. The performance of your network usually increases when
a large packet size is used.
ADVANCED DRIVER OPTIONS
The SK98WIN.SYS driver supports various advanced options, which
should only be set in one or more of the following cases:
- Troubleshooting a specific problem.
- Fine-tuning network performance.
The driver's advanced options can be set as follows:
**************************************************************************
CAUTION:
Setting any advanced driver options can dramatically change the behaviour
of the driver. This can lead to serious system or network problems. So
care must be taken when any driver options are set by the user.
If the driver is ever misconfigured in such a way that it no longer
operates properly, then remove and re-install the driver. This causes the
default values for all options to be restored.
**************************************************************************
Step 1.
Start the Registry Editor tool REGEDIT.
Step 2.
All of the driver's options are stored in the system's registry
database. Open the path to the driver's options:
\HKEY_LOCAL_MACHINE
\SYSTEM
\CurrentControlSet
\Services
\SK98WINx
\Parameters
Where the 'x' in SK98WIN must be replaced by the instance
number of the driver, i.e. SK98WIN1, SK98WIN2, etc.
Step 3.
You can now do the following:
- Modify an existing driver option by double-clicking it.
- Create a new driver option by clicking EDIT / NEW and then
selecting the type for the new option: "String", "Binary" or
"DWORD". The type required by each particular driver option is
listed in the "Type:" field in the description below.
- Delete an existing driver option by selecting it and then
clicking EDIT / DELETE. In this case, the driver will use its
built-in default for the deleted option.
Step 4.
After you have finished changing driver options, reboot the machine.
**************************************************************************
NOTE:
The machine must be rebooted before any changed options can take effect.
**************************************************************************
The following is a list of advanced options supported by the SK98WIN
driver.
NOTE: Most of the advanced options are not present in the registry by
default. These options must first be created via EDIT / NEW. Note that in
the absence of any option, the driver will use its built-in default value
for that option, as described by "Default value:" below.
MaxReceives
-----------
Type: DWORD
Default value: 20 multiplied by the number of CPUs in the system
Valid range: 3..200 (decimal)
This option allows you to specify the number of receive buffers that the
driver will allocate. Increasing the number of receive buffers can
sometimes improve network performance. Each receive buffer consumes about
1500 bytes of system memory.
MaxTransmits
------------
Type: DWORD
Default value: 7 plus the number of CPUs in the system
Valid range: 4..100 (decimal)
This option allows you to specify the number of transmit buffers that the
driver will allocate. Increasing the number of transmit buffers can
sometimes improve network performance. Each transmit buffer consumes about
1500 bytes of system memory.
MaxMulticast
------------
Type: DWORD
Default value: 128 (decimal)
Valid range: 0..10000 (decimal)
This option specifies the maximum number of multicast addresses that the
driver accepts.
FixedIntMod
-----------
Type: DWORD
Default value: 0
Valid range: 0 = "Off", 1000..100000 (decimal)
This option allows you to specify the maximum number of hardware interrupt
requests (IRQ) that the driver will allow for the adapter per second.
Modifying this option can improve the performance of your system under
heavy load conditions.
AutoNegotiation_<n> <n> = port designator (A or B)
-------------------
Type: DWORD
Default value: 2
Valid range: 0 = "Off"
1 = "On"
2 = "auto-sense"
NOTE: If this parameter if set to 0 ("Off") and 'DuplexCapabilities' is
set to 3 ("both half and full duplex") the driver will override the
setting and use 1 ("On") instead.
This parameter sets the auto-negotiation mode. This parameter can be set
for each port individually.
This is helpful if the port at the other end of the cable is limited in
its capabilities. Using the default setting, the
SysKonnect SK-NET Gigabit Ethernet Adapter SK-984x should automatically
detect the capabilities of the peer port.
DuplexCapabilities_<n> <n> = port designator (A or B)
----------------------
Type: DWORD
Default value: 3
Valid range: 1 = "half duplex"
2 = "full duplex"
3 = "both half and full duplex"
NOTE: This parameter is ignored if 'AutoNegotiation' is set to 2
("auto-sense").
This parameter can be used to limit the duplex capabilities that the port
reports during auto-negotiation. This parameter can be set for each port
individually.
This is helpful if the port at the other end of the cable cannot handle
all possible combinations. Using the default setting, the
SysKonnect SK-NET Gigabit Ethernet Adapter SK-984x should automatically
detect the capabilities of the peer port.
FlowControl_<n> <n> = port designator (A or B)
---------------
Type: DWORD
Default value: 3
Valid range: 0 = "no flow control"
1 = "asymmetrical flow control"
2 = "symmetrical flow control"
3 = "both asymmetrical and symmetrical flow control"
NOTE: This parameter is ignored if 'AutoNegotiation' is set to 0 ("Off").
This parameter can be used to set the flow control capabilities that the
port reports during auto-negotiation. This parameter can be set for each
port individually.
This is helpful if the port at the other end of the cable cannot handle
all possible combinations. Using the default setting, the
SysKonnect SK-NET Gigabit Ethernet Adapter SK-984x should automatically
detect the capabilities of the peer port.
