We tried several of these NICs in October.  We were unable to get the March
2001 drivers to run stably on the Tyan 24xx motherboards.  With even

The Tyan newsgroup also reports problems with this NIC under W2K and there
are supposed to be patches available via 3COM tech support.  We haven't yet
gotten a reply from 3COM tech support regarding the Linux drivers.

We moved on to other things and I'd hoped to see someone else's comment here
about revised drivers.  If there has been one, I haven't seen it.
