[CentOS] ethernet card name eth1 randomly changes

im having problems installing my nic card. my eth1 keep on renaming randomly to dev****. whenever i change the ifcfg network scripts at sysconfig and reboot, the nic tends to renamed randomly. i have tried changing this thing from davicom to 3com nic's.

dev6278 Link encap:Ethernet HWaddr 00:01:02:91:01:6D BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) Interrupt:11 Base address:0xdf00

any one experienced this already? suggestions are highly recommended. thanks guys!
