I am using Sharp PC-FJ120R with a Kingsoft PCMCIA ethernet card. I
though it is because Fedora lack the driver of the ethernet card. But my
friend said that the machine works well with Redhat 7.0......

Any suggestions?

Comment out the pcnet_cs entry in /etc/modprobe.conf, and set ONBOOT=no in /etc/sysconfig/network-scripts/ifcfg-eth0, and reboot. Actually an 'rmmod pcnet_cs' and 'service pcmcia restart' should work in lieu of rebooting.

The problem is your ethernet pcmcia card driver module is being loaded before pcmcia is started and the card controller module is loaded. This fails to work of course, and the later starting of pcmcia fails because the controller module conflicts with the already loaded card driver. The two changes above remedy the order things start in, and you will find that the ethernet interface does get started automatically at boot, because once pcmcia is started the card is detected and the interface for it is started.
