Sure I've a D-Link DFE-530TX+ and have all the dma interrupt and memory info also
Okay that info will help if the modprobe doesn't find it itself.
As a quick overview, the modules of the kernel are compiled and installed as part of the kernel setup, which as part of a stock linux install they are for you already. A list of dependacies and stuff are built to make your life a lot easier and modprobe is designed to query for the particular type of hardware and set it up with I/O DMA IRQ etc.. as required.
Having a quick nose at a default RH7.2 install there is a set of DLink drivers (I've had to get a DE600 or something working before) and it could be the defxx is the one you want.
Login as root on your machine, type ifconfig into a shell and it should list the active network devices. One should be called lo and unless you have anything else in there, nothing else will be listed. Now type "modprobe defxx" (which hopefully should return without errors) and typing ifconfig should now list lo along with a eth0.
If this has worked, you can use the menu driven netconfig command (type into a xterm or console shell) to setup the network, it'll go through the IP, Gateway, DNS, Subnet stuff with you and setup the config files and save them.
What is odd, is that it didn't detect the hardware for you, as its usually pretty good at that for you... and having just checked the Network Adapters compability list I quote..
DLink DE-220P, DE-528CT, DE-530+, DFE-500TX, DFE-530TX
As you can see, your network card is on there.
As for setup and other things you might want to read, the HOWTO collection is pretty good, and I've found most stuff I want in it. As a point I'm a bit of a command link junkie, as anyone who knows me will tell you (*waits for Samson to mutter* ) and while I know there are X progs to configure all this, I don't know of them due to my preferance for the command line.
Anywho, the networking HOWTOs can be found at Linux Networking HOWTOs and there is a general catagorized list HOWTOs, Catagorized List of HOWTOs
Of course if you have probs, ask
