Does your card still work on the net? I have had that problem occur
using Redhat 5.1 on a Dell Optiplex, also with a 3c509B card. I was
also using version .99E of the driver. It turned out that this occurred
only when the card was set to 10MB half duplex. If I changed it to
100MB full duplex the error went away. In either case I was able to
connect to the network fine with no errors. I decided after much
searching for people with this same problem that it was unique to Dell's
for some reason and that the error had no impact. Thus, I am ignoring
the message. I have had systems up and running this way for months now,
with no problems.
