	Back in October of last year, I cooked up a pccard.conf entry for 
it that seemed to mostly work:

# Belkin F5D5020 NE2000-compatible card (FCC ID: LXLC1LANTB)
card "Belkin" "F5D5020-PCMCIA-Network-Card"
         config	auto "ed" ?
         logstr	"Belkin F5D5020 10/100 Base-TX Ethernet 16-bit PCMCIA 
card (NE2000-compatible)"
         insert	/etc/pccard_ether $device start
         remove	/etc/pccard_ether $device stop

	I submitted this to Warner Losh, but IIRC, I got an indication 
back that this wasn't right.  However, I don't recall that I ever got 
any correct pccard.conf setting for this device, and while I could 
get FreeBSD to see the card and use this entry to mostly recognize 
it, I could not actually get any positive network results this way.

	Any additional information you can find would be appreciated. 
Right now, I'm using a Linksys (EtherFast 10/100 Integrated PC Card 
(PCM100) on the machine where I was trying to use the Belkin, but it 
sticks out from the machine and blocks the second PC Card slot, so 
I'd prefer to use the Belkin (which is flush with the edge and comes 
with a dongle), if possible.

	If I could get them both working, or get one of them working with 
one of my various 802.11b WiFi cards, then I would have two NICs and 
could do some much more interesting things with this machine. 
Unfortunately, everything seems to want IRQ3, so even if I could get 
the individual cards working by themselves, I don't know if I could 
ever get them working together.

	I did find an interesting entry at 
at the bottom (dated April 2002) that shows the pccard.conf entry of:

		# Belkin F5D5020
		card "Belkin" "F5D5020-PCMCIA-Network-Card"
		config  auto "ed" ? 0x10
		insert  /etc/pccard_ether $device start
		remove  /etc/pccard_ether $device stop

	Which the author claims (claimed) works (worked) for him.

	You can see my posts from October of last year at 
And then there's the post at 
from April, which also mentions this card.

	But still, no answers to this question.  Unfortunately, just 
Googling for "Belkin F5D5020 FreeBSD" doesn't do much good, as it 
turns up many resellers of this card which claims that it works with 
FreeBSD, or articles that happen to mention both FreeBSD and this 
card on the same page (such as 
<>), but which don't 
actually provide any solutions.
