With good ethernet card drivers, and extra tweaks in the internet stack for speed, _who_ needs the EtherExpress Pro/100 SmartAdapter???? Nobody. Especially at that cost. (I like the way is says '...has a PCI bus...' - wow what a new concept!) I don't think FreeBSD supports it. I'd be suprised to see anyone having one of these cards. As far as your original questions go: 'Switched' ethernet depends purely on the (switched) hub used, not the NIC. All the nodes on the local network share the same hub, but before switched hubs, data was broadcast to the whole network physically. AFAIK, 10Mb and 100Mb networks are functionally the same (apart from needing the extra hardware support), but both 10Mb and 100Mb carrier signals can be used.
