Network adapter without transformer?

[larry moe 'n curly]

Every network adapter I've seen, whether on a PCI card or built into a
motherboard, had a transformer, but I don't see any for the one on a
Biostar M7VIZ. At the rear it has a combination connector for an
ethernet socket and two USB ports. Could the transformer be built into
this connector? It was made by Amp and is covered with stainless
steel, but so are similar-looking devices on other motherboards that
definitely had separate transformers.

Wierd. I haven't seen one of those on a NIC for donkeys years.

The transformer I'm referring to is encapsulated in a small rectangular
chunk of black plastic, usually located right next to the Ethernet
connector, like this: http://tinyurl.com/czc8o (upper left, runs
vertically) or this: http://tinyurl.com/9f864 (near middle, between
black north bridge heatsink and silver box near top; this transoformer
is less oblong). In comparison, this BioStar mobo:
http://tinyurl.com/7u64r (upper right corner -- the square black things
next to the vertical cylindrical capacitor are MOSFETs, not a
transformer) has no visible transformer.

Is the NIC working ???

Then what the **** is your problem ???

guido,
it has to do with intelligence.

THat's because its not working as a transformer.

Then what is it working as? The spec sheet for it says "10/100 Base
Pulse Transformer":

Does a "transformer" make the NIC more " intelligent" ?
DUH !

Very possible, there are such connectors, i.e.
"http://trxcom.en.alibaba.com/produc...5_Connector_with_Lan_Transformer/showimg.html"

AMP most likely has something similar. I'd be surprised if it's cheaper
than an external transformer, but it does save space.
