To overwrite the driver's default values,
add or edit the following values in the Registry
CB100<adapter_number> Parameters subtree by
using the Registry Editor. The Registry Editor can be executed by
typing "regedit" at Start-up menu -> Run, and press <return>.
CacheLineSize = REG_DWORD { 32 | 64 | 128 }
32 bytes (default)
64 bytes
128 bytes
ExtraReceiveBuffers = REG_DWORD {value} (default: 16)
Number of buffers allocated by the
driver in the Receive look_aside list.
ExtraReceivePackets = REG_DWORD {value} (default: 100)
Number of packets preallocated by the
driver.
InterruptMitigation = REG_DWORD {0 | 1}
0 Disabled (default)
1 Enabled
Enable/disable the Interrupt Mitigation
algorithm.
InterruptThreshold = REG_DWORD {value} (default: 500)
Maximum number of interrupt/second allowed before
the Receive and Transmit interrupts get masked.
Meaningfull only when InterruptMitigation is enabled.
FrameThreshold = REG_DWORD {value} (default: 400)
Minimum number of processed frame/second allowed
before the Receive and Transmit interrupts get
unmasked.
Meaningfull only when InterruptMitigation is enabled.
EXT_MRM = REG_DWORD { 0 | 1 }
0 Disabled
1 Enabled (default)
Enable/disable PCI Memory Read Multiple command.
MRM should be enabled when the CB100 is connected
to the TI1130 PCI/CardBus bridge.
EXT_MRL = REG_DWORD { 0 | 1 }
0 Disabled
1 Enabled (default)
Enable/disable PCI Memory Read Line command.
EXT_MWI = REG_DWORD { 0 | 1 }
0 Disabled
1 Enabled (default)
Enable/disable PCI Memory Write and Invalidate command.
Due to incompatibility problems with certain PCI host bridges
and PCI-to-PCI bridges, the driver currently does not enable
the Memory Write Invalidate (MWI) and Memory Read Line (MRL) commands
simultaneously. The driver will only enable one of the two commands;
by default, MRL will be enabled.
ReceiveBuffers = REG_DWORD {8..64} (default: 16)
Number of buffers allocated by the
driver in the Receive ring.
UnderrunRetry = REG_DWORD number_of_retries (default=2)
Maximun number of retransmission attempts of
an underrun packet.
UnderrunThreshold = REG_DWORD number_of_underruns (default=10) (21140 and 21143/2 only)
Maximun number of underrun occurences before the
controller switches to the next threshold value.
BurstLength = REG_DWORD { 0 | 1 | 2 | 4 | 8 | 16 | 32 }
0 unlimited

SnoozeMode = REG_DWORD { 0 | 1 }
0 Disabled (default)
1 Enabled
StoreAndForward = REG_DWORD { 0 | 1 }
Select the StoreAndForward mode if high
PCI latencies causes 100Mbps Transmit Underruns
1 Enabled
0 Disabled (default)
TransmitThreshold = REG_DWORD { 72 | 96 | 128 | 160 }
Transmit Threshold values for 10Mbps media.
72 bytes
96 bytes (default)
128 bytes
160 bytes
TransmitThreshold100 = REG_DWORD { 128 | 256 | 512 | 1024 }
