[vortex] Mini PCI card question

[fes]

Yes, this is definitely my fault for not being careful enough.  Now that I
am at work, I'll boot to Linux and assess the damage.

I greatly appreciate the help from everyone.  Hopefully, I'll be able to
salvage the card.

The funny thing I was thinking about when the card was still working was
that I was dumping my EEPROM and thought that I sould save it off.
Unfortunately, I didn't.  I do have the ethernet address saved off,
though.  So if anyone has a quick dump of an EEPROM from one of these
cards, it might be beneficial.

Thanks,
Frank
