network configuration problem in Fedora

We have an "old" embedded system with fedora 7 on it. I can perform some minor changes/updates on it but upgrade the whole system to higher version of fedora (10/11) can't be done without big hassle. My problem is, the IP address I assign to the NIC won't take effect only by restarting the NIC. I have to reboot the computer to make it happen. I've tried using the GUI network configuration tool and manually edit the etc/sysconfig/network/devices/ifcfg-eth0 file (only one NIC), no luck. The address in the file did change though. Any idea? Thanks!

BTW: There seems no more update support for fedora7, at least not from the default updater.
