I assure you I won't give up until we all run out of ideas! ;)

Back to the problem; I already tried increasing the debugging verbosity to
6, nothing out of the ordinary is reported in /var/log/messages, neither
during boot-up nor afterwards. But it gets even weirder: my laptop is set
to seek DHCP connection during its boot-up and if the crossover cable is
connected to the desktop computer, media link is found and recognized as
100Mbit full duplex. Since dhcpd isn't running, nothing happens, but I
guess that for this to happen, network cards have to talk to each other,
right? I also checked /proc/interrupts, which are increasing as they
should, /proc/dev/net seems ok as well. Everything is ok that I can tell,
except for this glitch of not working at all! ;)

I also tried 3c90x driver, but it returns Device not found error. For more
information I'm attaching the output from logs & trials.

Thanks,

Andrej

*** Testing 3c59x driver: ***

Compilation smooth. Module insertion smooth.

/proc/interrupts increases in time
/proc/net/dev sane (responds to pinging)
When probing, 100Mbit full duplex detected.

However, no link via crossover cable may be established.
