I've struggled with some software configurable isa ne2k's. They appeared
to function quite nicely with linux, but win95's autoprobing had severe
difficulties with the cards. The dos configuration utility would let me
change io and irq settings just fine, I could also write them to the
"register" but not to the card's eeprom, giving me an error in the
card's own setup utility.
The problem appeared to be that the cards used a different combination of irq
and io for configuration and actual operation. It listened only half the
time to the operation addresses and the configuration addresses were
conflicting with other hardware.
This kept me stumped for quite a while and until I figured it out I too
had long bought pci cards (which also gave some trouble <sigh>.)
This was the solution in my case:
-on the motherboard bios setup, disable com2:, freeing irq 3.
-with the dos utility, set the io and irq to what the card uses to
receive programming data.
-then set it to what would suit the computer's available interrupts and
io addresses. Don't forget to write the settings to the card's eeprom.
In your case, the conflicts may ofcourse be a little bit harder to
resolve before you can access the card again. Maybe it doesn't work
altogether on your card. Maybe it's really burnt. You can always try.

Hmmm, I bought winbonds. They don't work without a patch. It would be
great if this patch would make it to the next bootfloppy, or even better
- 2.0.31. Until then, I have to make my own rescue-floppy kernels.

Please check my solution if that may help you, if the reprogrammed io and
irq aren't too outrageous there may still be hope.
I think that it is however possible to fry hardware with linux: while
trying 1.3 I inserted a wrong module for the cdrom interface and it fried
the cdrom drive.
