hullo,
ive been reading thru the archives of the mailing lists as well as the
page by Donald Becker, but i didnt really find a solution to the
problem (shame on me if i overlooked it):
ive got a 3c905b Cyclone card in my linux box, and when powering
it on, the 100mbit led on the hub (surecom ep-808x, an 8 port
nway switching and autosensing hub) goes on, and as soon as the
boot process is finished, it goes off again.
any windows machine on the same network works fine with 100mbit/s and
the same card.
heres my collected output from various commands:

The Vortex chip may be active, so FIFO registers will not be read.
To see all register values use the '-f' flag.

networking is fine, except that im running at 10mbit/s while id like
to run at 100mbit/s :-)
my kernel version is 2.0.35, and the driver is not compiled as a module.
i give those arguments to /etc/lilo.conf: append="mem=256M ether=0,0,eth1"
any help or pointer would be really appreciated.
