RHEL 5.8 doesn't see all network adapters


This is ifconfig results from Ubuntu:
Code:
eth0      Link encap:Ethernet  HWaddr 00:23:ae:99:9b:b7 
          inet addr:192.168.100.10  Bcast:192.168.100.255  Mask:255.255.255.0
          inet6 addr: fe80::223:aeff:fe99:9bb7/64 Scope:Link

          RX bytes:0 (0.0 B)  TX bytes:4029 (4.0 KB)
          Memory:fe6e0000-fe700000
eth1      Link encap:Ethernet  HWaddr 00:1b:21:5e:28:af 
          inet addr:10.192.190.61  Bcast:10.192.190.255  Mask:255.255.255.0
          inet6 addr: fe80::21b:21ff:fe5e:28af/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:374 errors:0 dropped:0 overruns:0 frame:0
          TX packets:66 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:45154 (45.1 KB)  TX bytes:8894 (8.8 KB)
          Memory:fe260000-fe280000
In RHEL 5.8:
Code:
eth0      Link encap:Ethernet  HWaddr 00:23:AE:99:9B:B7  
          inet addr:10.90.185.67  Bcast:10.90.185.255  Mask:255.255.255.0
          inet6 addr: fe80::223:aeff:fe99:9bb7/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:2760 errors:0 dropped:0 overruns:0 frame:0
          TX packets:2434 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:1109942 (1.0 MiB)  TX bytes:480153 (468.8 KiB)
          Interrupt:50 Memory:fe6e0000-fe700000
Both also include loopback adapter. So, RHEL doesn't see eth1. How can I fix this?

1. Check "ONBOOT= " status in eth1 configuration file. It should be "ONBOOT=yes"
2. Run command "dmesg | grep eth". It should show eth1 interface.
