This card is supported, but there is no mention of this on D-Link's website.
If it isn't Windows or Novell, they don't care. Shame on you D-Link.
Get with the program. At least have a "not officially supported but
it works on redhat by doing this" informational page. Vote with your
dollars - if it doesn't say linux on the box, don't get it, if possible.
(I assumed a company the size of D-Link would have at least basic support/info
Okay, enuf soapboxing.
How I got it going (having never dealt with pcmcia stuff before it was a
bit of the learning something new in linux adventure game one goes thru)
yields quite a few items. Of significance are cardmgr and cardctl.
And, unlike far too many programs, the man pages for both of these are excellent.
Read up a bit, esp. the "FILES" and "SEE ALSO" sections.
Okay, so stick the card in. I suggest only having this one card in
to keep things simple.
yields very basic "5V 16 bit PC Card" and "Ready" for the socket its in.
"/sbin/cardctl ident [socketnum, either 0 or 1]"
product info: "D-Link" "DFE-670TXD" "PC Card"
manfid: 0x0149, 0x4530
function: 6 (network)
if it doesn't something is wrong, or at least different than what I get.
Okay, so how does this pcmcia stuff work?
Reading the manpage for cardmgr, it looks like cardmgr gets notified of
a card insertion somehow, it reads the product info and whatnot from the
card, tries to match it up in a database of cards -> drivers (/etc/pcmcia/config),
and loads the appropriate driver and does the beep. If the card doesn't
have an entry in /etc/pcmcia/config, there is no driver to load and it does
a lower pitched beep.
Looking at /etc/pcmcia/config I see that similar-sounding cards from D-Link
are supported: DFE-650, DFE-660, and others. Doing a google (god bless
google!) search on DFE-670 produced the info that it is supported, but the
two pages found don't say how to set it up. The page at pcmcia-cs.sourceforge.net
listing compatible cards has it under "pcnet_cs driver", so the existing entry
for the DFE-650 in /etc/pcmcia/config is probably the one to copy and tweak.
At the end of /etc/pcmcia/config it has a "source" command to include any
file in /etc/pcmcia ending in .conf. How handy and thoughtful.
So (as root of course) make a new file /etc/pcmcia/dfe-670.conf, and in it
copy the entry for DFE-650 from /etc/pcmcia/config, and tweak it to read as
card "D-Link DFE-670TXD PC Card"
manfid 0x0149, 0x4530
Yes, you want to have the quotes! Save the file, now eject the card,
push it back in, and ...
boop. No worky. Heh. Turns out that cardmgr is a fancy
little program, and it doesn't parse /etc/pcmcia/config each time a card is
inserted - that info (and some hardware settings) are cached after the first
read. So, you have to send the cardmgr daemon a SIGHUP to reload all
its configuration stuff. Do that, eject the card, push it back in,
and you should get the beep of success!
