Possibly the PCMCIA manager is interfering with things.  This was true
with my laptop and its PS/2 mouse.  BTW you say "Busmouse" do you mean
it?  Busmice are old critters, PS/2 is not the same as Bus (bus has it
own card).

Except for adding the second card, they are easy.

/etc/rc.d/init.d is where the files are
/etc/rc.d/rc3.d is the directory of links for starting and stopping
Level 3 programs (normal run level for RedHat).	 Thus S10network is
called then S30syslog.  S10network points to ../rc3.d/S10network.

Now reading that takes a bit work

. /etc/rc.d/init.d/functions is the bulk of the script functions, keep
ypur eye on this file.

. /etc/sysconfig/network is where the work is done

cd /etc/sysconfig/network-scripts is where you need to edit

but for now look at:
                for i in ifcfg-eth?; do
                    if [ -e $i ]; then
                        ./ifup-eth $i boot
                    fi
                done


For every file ifcfg-eth? (eth0, eth1, etc.) run ifup-eth
/etc/sysconfig/network-scripts/ifcfg-eth0:
#!/bin/sh

#>>>Device type: ethernet

#>>>Variable declarations:
DEVICE=eth0
#IPADDR=192.168.200.73
IPADDR=206.29.195.17
NETMASK=255.255.255.240
#NETWORK=192.168.200.0
NETWORK=206.29.195.16
#BROADCAST=192.168.200.255
BROADCAST=206.29.195.255
GATEWAY=none
ONBOOT=yes
#>>>End variable declarations

So you need to build an ifcfg-eth1

/etc/sysconfig/network-scripts/ifup-eth:
#!/bin/sh
PATH=/sbin:/usr/sbin:/bin:/usr/bin
. $1 ###this loads the variables for eth0, eth1, etc.
if [ "foo$2" = "fooboot" -a ${ONBOOT} = "no" ]
then
        exit
fi
ifconfig ${DEVICE} ${IPADDR} netmask ${NETMASK} broadcast ${BROADCAST}
#route add ${IPADDR}
route add -net ${NETWORK} netmask ${NETMASK}
if [ "${GATEWAY}" != "" -a "${GATEWAY}" != "none" ]
then
        route add default gw ${GATEWAY} metric 1
fi

--------------
Now I had to edit this logic on a couple of client machiens, but now you
see where to affect.

Now is this more complicated?  Yes.  IS it better?  Yes.  Why?  You
weant to start or stop services (like in NT) you merely call
/etc/rc.d/init.d/network stop|start

Same for httpd.init, named.init and the others, very usueful for setting
up, and for cron jobs.

Take a bit to get used to, though I've been told other unixes are moving
that way.

LUN 3?  or ID 3?  Lun is a subset of ID.  You mean its the third
device?  Look at dmesg (or /var/log/messages)  When the scsi driver
scans, it reports the found drives.  You did use a kernel with cdrom
compiled in, didn't you?
