Description Sammy 2000-12-06 14:52:52 UTC

I have RH7.0+updates running on a DELL Inspiron 3800 notebook.
As the networking card I have Xircom 10/100 CE.. networking
card (no modem). The card is recognized by linux and it actually
works (uses tulip_cb driver) BUT when trasferring files it becomes
extremely slow. I substitute the PCMCIA card with a 3Com card and
it is blazingly fast. I read about problems with Xircom cards but
could not find a solution. I ported the pcmcia-3.1.22 package and
started using that but that did not solve the problem either. Any
suggestions would be appreciated.

The card is Xircom CBE2-100

I have been playing around with a Xircom CBEM56G under RedHat 7.2. This laptop
used to work great under RedHat 6.2. It has always had problems with newer
releases unless I rebuilt the kernel with an old PCMCIA driver set from the 6.2
days.

Recently I am having some success with a 2.4.9-21 kernel if I do the following:

1) shut down networking (service network stop)
2) remove the xircom_cb module (modprobe -r xircom_cb)
3) add the xircom_tulip_cb module (modprobe xircom_tulip_cb)
4) restart networking (service network start)

I have a script in /etc/init.d which does just this.

Using netperf perfomance went form < 20 Mbits/sec to > 75 Mbits/sec.

My question is, how is this selection supposed to be made without resorting to a
seperate init.d script? I have tried changing the /etc/pcmcia/config file with
no luck. I also saw references to hotplug. I saw that xircom_tulip_cb was in
/etc/hotplug/blacklist. I removed it and inserted xircom_cb in it's place. This
got me no xircom module loaded at all until I did it manually.

OK, I saw another xircom thread that mentioned using an "alias eth0
xircom_tulib_cb" entry in /etc/modules.conf. This has eliminated the need to run
an init.d script.

xircom_tulip_cb now handles this not quite tulip hw fine
