Networking :: What to do when networkcard isn't detected?



I have a Marvell Yukon ethernetcard which worked pretty much with every distro I tried. However when I want to set up my networkcard for a DHCP connection in DSL I get the message:"no supported networkcard found'  ??? Any suggestions on how to proceed?
"modprobe sk98lin"  gives me:
                                     
/lib/modules/2.4.26/kernel/drivers/net/sk98lin/sk98lin.o: create_module: Operati                                                                                      on not permitted
/lib/modules/2.4.26/kernel/drivers/net/sk98lin/sk98lin.o: insmod /lib/modules/2.                                                                                      4.26/kernel/drivers/net/sk98lin/sk98lin.o failed
/lib/modules/2.4.26/kernel/drivers/net/sk98lin/sk98lin.o: insmod sk98lin failed
Are you in root while doing that?
I did a "sudo su modprobe sk98lin"  hence it didn't work. When I issued a "sudo su" first followed by a "modprobe sk98lin" I got my network working   :)  One more question how do I make it permament? In other words; where can I put the (executable) file "rc.netdevice" with the line "/sbin/modprobe sk98lin" in it? I noticed that DSL has more than one /etc/rc.d folder....
You can add the command "modprobe sk98lin" (note no sudo) to the file /opt/bootlocal.sh.  It will then run at boot time.
