Disable transceiver. On those cards which support it, this flag causes the transceiver to be disabled and the AUI connection to be used by default.
Force 8bit mode. This flag forces the card to 8bit mode regardless of how the card identifies itself. This may be needed for some clones which incorrectly identify themselves as 16bit, even though they only have an 8bit interface. This flag takes precedence over force 16bit mode.
Force 16bit mode. This flag forces the card to 16bit mode regardless of how the card identifies itself. This may be needed for some clones which incorrectly identify themselves as 8bit, even though they have a 16bit ISA interface.
Disable transmitter multi-buffering. This flag disables the use of multiple transmit buffers and may be necessary in rare cases where packets are sent out faster than a machine on the other end can handle (as evidenced by severe packet lossage). Some ( non- Fx :-)) machines have terrible Ethernet performance and simply cannot cope with 1100K+ data rates. Use of this flag also provides one more packet worth of receiver buffering, and on 8bit cards, this may help reduce receiver lossage.
When using a 3c503 card, the AUI connection may be selected by specifying the link2 option to ifconfig(8) (BNC is the default).
The IRQ number that was specified in the kernel config file (and then compiled into the kernel) differs from the IRQ that has been set on the interface card.
"ed%d: failed to clear shared memory at %x - check configuration."
When the card was probed at system boot time, the ed driver found that it could not clear the cards shared memory. This is most commonly caused by a BIOS extension ROM being configured in the same address space as the Ethernet cards shared memory. Either find the offending card and change its BIOS ROM to be at an address that does not conflict, or change the .Cd iomem option in the kernel config file so that the cards shared memory is mapped at a non-conflicting address.
"ed%d: Invalid irq configuration (%d) must be 2-5 for 3c503."
The IRQ number that was specified in the kernel config file is not valid for the 3Com 3c503 card. The 3c503 can only be assigned to IRQs 2 through 5.
"ed%d: Cannot find start of RAM." "ed%d: Cannot find any RAM, start : %d, x = %d."
The probe of a Gateway card was unsuccessful in configuring the cards packet memory. This likely indicates that the card was improperly recognized as a Gateway or that the card is defective.
"ed: packets buffered, but transmitter idle."
Indicates a logic problem in the driver. Should never happen.
"ed%d: device timeout"
Indicates that an expected transmitter interrupt did not occur. Usually caused by an interrupt conflict with another card on the ISA bus. This condition could also be caused if the kernel is configured for a different IRQ channel than the one the card is actually using. If that is the case, you will have to either reconfigure the card using a DOS utility or set the jumpers on the card appropriately.
"ed%d: NIC memory corrupt - invalid packet length %d."
Indicates that a packet was received with a packet length that was either larger than the maximum size or smaller than the minimum size allowed by the IEEE 802.3 standard. Usually caused by a conflict with another card on the ISA bus, but in some cases may also indicate faulty cabling.
"ed%d: remote transmit DMA failed to complete."
This indicates that a programmed I/O transfer to an NE1000 or NE2000 style card has failed to properly complete. Usually caused by the ISA bus speed being set too fast.
