Re: Lots of RX errors... ??? ...

I found out that Davicom does have a web site with a Linux driver for 
the DM9000 chip.  However, it was last updated on 2001/11/09.

Does anyone have experience with this driver or know of an update?
Hmmm...  Actually, how do I verify that the chip on this MB is a 9000 
and not something else?

This is for a low throughput home firewall box, so I would hate to swap 
out the MB just because of the bad built in NIC.

Thanks!
