Here they is:
1. The kernel detecting the cards:
3c59x.c:v0.99E 5/12/98 Donald Becker
http://cesdis.gsfc.nasa.gov/linux/drivers/vortex.html
loading device 'eth0'...
eth0: 3Com 3c905B Cyclone 100baseTx at 0xb800, 00:10:4b:98:e5:5a, IRQ 10
8K byte-wide RAM 5:3 Rx:Tx split, autoselect/NWay Autonegotiation
interface.
Enabling bus-master transmits and whole-frame receives.
loading device 'eth1'...
eth1: 3Com 3c905B Cyclone 100baseTx at 0xb400, 00:10:4b:cd:0a:c7, IRQ 11
8K byte-wide RAM 5:3 Rx:Tx split, autoselect/NWay Autonegotiation
interface.
Enabling bus-master transmits and whole-frame receives.
2. Output of ifconfig
[root at pbreton network-scripts]# ifconfig

3. Routing tables
[root at pbreton network-scripts]# netstat -nr
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt
Iface
192.168.1.3 0.0.0.0 255.255.255.255 UH 1500 0 0
eth1
192.168.1.0 0.0.0.0 255.255.255.0 U 1500 0 0
eth1
24.128.88.0 0.0.0.0 255.255.254.0 U 1500 0 0
eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 3584 0 0
lo
0.0.0.0 24.128.88.1 0.0.0.0 G 1500 0 0
eth0
4. /etc/sysconfig/network-scripts files:
emacs at pbreton(4) [10:13:12]% cat ifcfg-eth0
DEVICE=eth0
IPADDR=
NETMASK=
ONBOOT=yes
BOOTPROTO=dhcp
USERCTL=no
emacs at pbreton(5) [10:13:17]% cat ifcfg-eth1
DEVICE=eth1
USERCTL=no
ONBOOT=yes
BOOTPROTO=none
NETWORK=192.168.1.0
BROADCAST=192.168.1.255
NETMASK=255.255.255.0
IPADDR=192.168.1.1
Any clues welcomed... right now I'm mystified, and am back to thinking
that it may be the card after all.
