— DEC DC21x4x
(Tulip) 10/100 Ethernet device
de* at pci?
device driver supports Ethernet adapters
based on the Digital Equipment DC21x4x based self-contained Ethernet chips.
This includes, among others, the following models:
- Cogent EM100FX and
- DEC PCI DE435, EISA DE425,
- older Linksys 10, 10/100
- SMC 8432, 9332, 9334
- ZNYX ZX3xx
This driver may support other cards based on the 21040 and 21041 Ethernet
controllers, or the 21140[A], 21141, 21142, and 21143 Fast Ethernet
driver supports the following media types:
- Enable autoselection of the media type and options.
- Set 10Mbps operation on the 10baseT port.
- Set 10Mbps operation on the BNC port.
- Set 10Mbps operation on the AUI port.
- Set 100Mbps (Fast Ethernet) operation.
- Set 100Mbps operation.
- Set 100Mbps operation (4-pair cat-3 cable).
driver supports the following media options:
- Set full duplex operation for UTP port.
For more information on configuring this device, see
. To view a list of
media types and options supported by your card try
ifconfig <device> media
. For example,
ifconfig de0 media
Note that the media types available depend on the particular card in use. Some
cards are explicitly programmed to a particular media type by a setup utility
and are not changeable.
The old “ifconfig linkN” method of configuration is not supported.
- de0: waking device from sleep/snooze
- The 21041 and 21140A chips support suspending the
operation of the card.
- de0: error: desired IRQ of X does not
match device's actual IRQ of Y
- The device probe detected that the board is configured for
a different interrupt than the one specified in the kernel configuration
- de0: not configured; limit of N reached
- There is a limit of 32 de
devices allowed in a single machine.
- de0: not configured; 21040 pass 2.0
required (X.Y found)
- de0: not configured; 21140 pass 1.1
required (X.Y found)
- Certain revisions of the chipset are not supported by this

Since the 21040 is available on both EISA and PCI boards, one must be careful in
how one defines the 21040 in the kernel config file.
