I recently implemented code to talk to a Realtek 8019AS which is NE2000 compatible. I found the datasheet for the rtl8019as to be helpful, but somewhat incomplete. I used datasheet for the 8390 that you mentioned, but probably the best resource I found was National ap-note AN-874 "Writing Drivers for the DP8390 NIC Family of Ethernet Controllers." This ap-note basically walks through a driver written in x86 assembly. After working through AN-874 until I absolutely understood everything the driver was supposed to do, it wasn't too bad to get the controller working. It did take me a little while though because I had a couple addressing errors in my code. The general approach I took was to get ISA working to read/write registers. Then I got remote dma working with the controller. After you get those two things working, you can send ethernet frames and you 'just' need to build whatever ip or tcp stuff you want to handle on top of that.
