Anybody know where there's any documentation explaining network card programming?

I can kind of reverse engineer, but prefer to do things by knowing what I am doing as compared to hacking.

Thanks,

download menuetos and look through the source code. it is able to use my 3com card so i must have some code you can use.

Hi Pelaillo!

I have searched through internet and found out that several card manufactures have published their network card drivers written in pure asm. I think that could help you to some extent.

Look at Crynwr packet drivers collection. These are 16-bit real-mode ethernet drivers for DOS, written in asm (open source).

Thanks for all the help.
I knew about the Crynwr site, but kind of wanted the specs. After I looked at the Realtek specs, I guess just having the source code is not so bad. Man are there a lot of registers for programming network cards(not quite as easy as IDE hard drives).

Didn't want to go the menuetOS route or Linux route because I don't know their interfaces. At least with dos, I can easily read the code in sequential order. The other OS's I don't know which routine is called in what order and what is already set up.

Could find any asm sources on manufactures sites, but I didn't look too hard either.

Thanks again for the help.
