I remember Gergios telling me that this card worked in an older version of bf.

Am I mistaken that Lance is mostly an optimized/evolved version of NE2000, the basic specification behind the RTL NIC? I think it is sometimes referred to as NE2100. I am not saying that the cards are identical, rather their differences are minimal for basic
functionality.<br>

Hi Patrik,<br>
<br>
You should not need to modify rtl8029as.dev at all - its functionality<br>
hasn't changed since it was written originally (it's not a complex<br>
card), and reverting it will most likely break the existing driver.<br>
<br>
The file has changed because Mackerel acquired new constructs which<br>
made it much simpler to express things like arrays of registers, and<br>
non-standard address spaces, both of which the RTL uses.<br>
<br>
The best source of material for understanding the .dev file is the<br>
Mackerel manual (available on the web site and in the source code as a<br>
technical note), but as I said, you shouldn't need to modify this<br>
file, only the driver.<br>
<br>
Do you have a citation for the AM79C973 ever working? I don't think we<br>
have one here, and if I remember correctly the AM79C973 is compatible<br>
with the LANCE, rather than the RTL8029, and we don't have a LANCE<br>
driver...<br>
