to further muddy the water, D_Link has a history of saving the boxes and changing the contents instead of creating a new model, so their model numbers don't help much, you need revision levels and and chipset info to set up their products unless you have the install software from the original box.
I went to Tiger Direct, bought 3 different gigabit cards for $100, two of them worked with SME7, no way of knowing by looking at the boxes!
(VIA and Realtek chipsets worked, Marvell didn't )
I wasted half a day trying to make the Marvel card ( a dlink model that CLAIMS to work with RH4 according to their site ) work, it works fine in an XP machine.
