I googled and found
this.
Looks like you need to edit /etc/sysconfig/network-scripts/ifcfg-eth0 to looks something like this
Code:
# Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE]
DEVICE=eth0
BOOTPROTO=static
BROADCAST=192.168.0.255
HWADDR=00:0C:29:11:31:55
IPADDR=192.168.0.100
IPV6ADDR=
IPV6PREFIX=
NETMASK=255.255.255.0
NETWORK=192.168.0.0
ONBOOT=yes
Of course, change the network addresses to the correct subnet.
Good luck. If I'm wrong, I'll give you your money back...
