I doubt the vendor (NDC Communications Inc. in Sunnyvale) knows the meaning of the abbreviation SFA in large parts of the English-speaking world. The label on the packet indicates that they're revision B4. > - Step 2: Actually *look* at the card, with your eyeballs, and make note > of the part number on the controller chip.

It's a 98715. Oops, wrong answer. The chip has the following inscriptions: MX (large font) MX98715AEC-C M9941 TA151301 37DCX > - Step 3: With the card(s) installed in your machine, type the following > command: > > # pciconf -l > /tmp/pciconf.out Here's the complete output for one machine.

All the cards are the same, bought at Fry's on the 16th June. The other two may have different manufacturing dates, but I don't want to drag them out of the machines they're in just for that. > Once you have all of this information collected and formatted nicely, > e-mail it to me at wpaul@freebsd.org and I will generate a patch to > if_dc so that I can special-case these chips correctly.

You should probably send this to -CURRENT as well.
