The model number is similar to an ISA card I have in my Win 98SE machine. My card is a Linksys LNE2000T, named Ether16 10BaseT LAN Card. It has an RJ45 jack and I have it connected to my router via CAT5 cable. It works fine; Internet connection speed is the same as my main computer (Win XP, onboard LAN).
The only way you're going to know for sure whether will work is to try it. If it does not work, a driver update might solve the problem. I don't know where you can get a driver for it, since the brand name is not indicated. I see Linksys has a driver for my old card, but I don't know whether that driver would be appropriate for your card.
If you can't get it to work and you have an empty PCI slot, you could get a network card for a PCI slot.
