The 3c2000 driver has a bug that makes it not transmit UDP packets right, so I would recomend using the syskonnect driver for the chip that the 3c2000 uses instead of the 3com driver (which is just a hack of the syskonnect driver anyway). I should say the 3c2000T does, though I think they all use the same driver so I assume they would all have this problem. It makes LAM act very oddly.
Anyway, regardless of which driver you want to use, this is how I got my nodes with 3c2000T cards to boot nicely after cloning. This needs to be done on a cloned oscar node, so you need to install the following rpms on one kernel-doc kernel-source kernel-utils net-snmp-5 (or something like this) which are all on disk two. 1) Download the 2.4 series driver from syskonnect.com 2) Uses bz2 so untar with tar xjvf 3) cd DriverInstall 4) ./install.sh (pick user installation mode) 5) Add the following to /etc/modules.conf alias eth0 sk98lin 6) Driver is located in /lib/modules/2.4.20-8smp/kernel/drivers/net/sk98lin If this node works on reboot, make the same changes to the image file. So edit /var/lib/systemimager/images/oscarimage/etc/modules.conf and copy the driver from the node to /var/lib/systemimager/images/oscarimage/lib/modules/2.4.20-8smp/kernel/drivers/net If you want it to work with the non smp kernel too, just put the driver in the same directory as above only without the smp. I only ever boot my nodes in smp, so you might need to compile the non-smp version separately, I am not sure. I am working from my notes so I probably have some - and _ mixed up, possibly some other minor details, but I think this captures the general idea. You can also do more or less the same thing with the 3c2000 driver if you want to try it. I have some notes from that too if you decide you want to go that route and have problems.
