Hello...
I currently have two computers running slackware linux connected
together with a cross over cable.
(they also have another ne2k-pci type card each, which they use to talk
to another LAN - sm.net (private ip setup thing))
The nics connected to this cable are both rtl8139 based, but neither
wants to run at 100mb/s (they are stuck at 10mb/s)
Is there any way that i can tell them to run at 100mb/s ? (eg a command
to put in the /etc/conf.modules or something similar, or a boottime
command to go in /etc/lilo.conf ?)
I've read most of the realtrek related webpages by Donald Becker, but
they don't seem to mention anything about this.
I've run the rtl8139 diagnostic program which was on his webpage, and
the results are attached below.
As you can see neither card seems to want to autonegotiate.
Thanks in advance for any help.
David Goodwin

The RealTek chip appears to be active, so some registers will not be read.
To see all register values use the '-f' flag.
