Kirk, please read at least the final part of the message...

Sure, as long as there is no specific documentation about these chips. 
However, if we assume that the documentation for 905C still stands, the 
content is simply not valid.

I'm not debating this. My concern was about cards with invalid EPROM 
content; in this case, it happened that the invalid EPROM matched this 
"catch-all" pattern; but what if it didn't ? Your driver would then behave 
like the LK driver does now.

I actually wonder what would happen if I would put a DEC-based card PCI ID 
in this EPROM. Would the tulip driver detect it and try to drive it ?

Ouhh, far from me to criticize this. I didn't mean at all to touch PCI 
scanning matters... I appologize if it looked like this!

To come back to EPROM problems, I modified a bit vortex-diag to be able to 
save and load an EPROM image file. It's available along with a short 
description at:

http://www.iwr.uni-heidelberg.de/groups/biocomp/bogdan/tornado/

I used it with a Tornado card and it worked fine, but of course YMMV.
So, Kirk, if you're willing, you can use it by saving the image from the 
first adapter and loading it to the second adapter. If you want to modify 
the MAC address, you need to use a hex editor to modify it before you 
load it, but then it might be better if you would just load it like it is 
then use the "-H" option of vortex-diag (along with "-w" after making sure 
that it looks like you want to).
