Hello everyone,

I have a problem with a 3c900 Combo [Boomerang], used as a
second Ethernet adapter, on a Compaq Deskpro EN with RedHat 7.0.
This is a fresh Linux installation on a new PC. I installed
all current RH 7.0 update RPM's (as of Mar 2, 2001).

This PC has an embedded ethernet adapter (eth0). I plugged in
a PCI 3c900 which used to work on a former PC with RH 6.2 and
I cannot make it work. The system does not see it and seems
to be confused with the two adapters. The first adapter does
not work well either.

I configured the two adapters using linuxconf (do you know
a better command-line way?). Here is the resulting content
of /etc/modules.conf :

alias parport_lowlevel parport_pc
alias eth0 eepro100
alias usb-controller usb-uhci
alias eth1 3c59x
alias sound-slot-0 i810_audio

When the system boots, none of these adapters is configured.
Doing 'ifconfig', only lo0 is here. Doing 'ifconfig -a',
I can see that eth0 is here but not started. But eth1
does not appear.

Doing 'ifup eth0' sometimes works after boot. But the strange
thing is that 'lsmod' shows that 3c59x is loaded after 'ifup eth0'
(but it was an alias for eth1, not eth0).

Of course, since eth1 is not seen by 'ifconfig -a', 'ifup eth1'
never works.

- Could anyone help me fixing this?
- Where does this confusion between eth0 and eth1 come from?
- How can I force the creation of eth1 outside of linuxconf?

I tried to use 3c90x instead of 3c59x but the module does not load:

# ifdown eth0
# rmmod 3c59x
# insmod 3c90x
Using /lib/modules/2.2.17-14/net/3c90x.o
/lib/modules/2.2.17-14/net/3c90x.o: init_module: Device or resource busy
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters

Thank you in advance for your help.
