Caveats:

I am not sure if 100BaseTX daughterboards (for those cards which support such things) will work. I haven’t had any solid evidence either way.

However, if a card supports 100BaseTx without requiring an add on daughterboard, it should work with 100BaseTx.

The “Netelligent 10 T/2 PCI UTP/Coax” (b012) device is untested, but I do not expect any problems.

II. Driver Options

  1. You can append debug=x to the end of the insmod line to get debug messages, where x is a bit field where the bits mean the following:

    0x01

    Turn on general debugging messages.

    0x02

    Turn on receive debugging messages.

    0x04

    Turn on transmit debugging messages.

    0x08

    Turn on list debugging messages.

  2. You can append aui=1 to the end of the insmod line to cause the adapter to use the AUI interface instead of the 10 Base T interface. This is also what to do if you want to use the BNC connector on a TLAN based device. (Setting this option on a device that does not have an AUI/BNC connector will probably cause it to not function correctly.)

  3. You can set duplex=1 to force half duplex, and duplex=2 to force full duplex.

  4. You can set speed=10 to force 10Mbs operation, and speed=100 to force 100Mbs operation. (I’m not sure what will happen if a card which only supports 10Mbs is forced into 100Mbs mode.)

  5. You have to use speed=X duplex=Y together now. If you just do “insmod tlan.o speed=100” the driver will do Auto-Neg. To force a 10Mbps Half-Duplex link do “insmod tlan.o speed=10 duplex=1”.

  6. If the driver is built into the kernel, you can use the 3rd and 4th parameters to set aui and debug respectively. For example:

    ether=0,0,0x1,0x7,eth0

    This sets aui to 0x1 and debug to 0x7, assuming eth0 is a supported TLAN device.

    The bits in the third byte are assigned as follows:

    0x01

    aui

    0x02

    use half duplex

    0x04

    use full duplex

    0x08

    use 10BaseT

    0x10

    use 100BaseTx

    You also need to set both speed and duplex settings when forcing speeds with kernel-parameters. ether=0,0,0x12,0,eth0 will force link to 100Mbps Half-Duplex.

  7. If you have more than one tlan adapter in your system, you can use the above options on a per adapter basis. To force a 100Mbit/HD link with your eth1 adapter use:

    insmod tlan speed=0,100 duplex=0,1

    Now eth0 will use auto-neg and eth1 will be forced to 100Mbit/HD. Note that the tlan driver supports a maximum of 8 adapters.

III. Things to try if you have problems

  1. Make sure your card’s PCI id is among those listed in section I, above.

  2. Make sure routing is correct.

  3. Try forcing different speed/duplex settings
