First one was configured in nvram at startup.
Second one has been configure manually with in a config session.
Really what the router says :)

Are you familiar with the concept of "startup configuration" and "config term" in IOS ?

As Paolo stated, when you see an interface listed with Manual it means the IP address was configured on that interface after the router was rebooted.
For instance:
Router(config)#int s0/0
Router(config-if)#ip add 192.168.1.1 255.255.255.0
Router(config-if)#no shut
Router(config-if)#end
Router#sh ip int bri
*May 10 11:42:49.843: %SYS-5-CONFIG_I: Configured from console by console
Interface IP-Address OK? Method Status Protocol
Serial0/0 192.168.1.1 YES manual up up
Now, if I reboot the router, the interface chances to NVRAM.
Router#sh ip int bri
Interface IP-Address OK? Method Status Protocol
Serial0/0 192.168.1.1 YES NVRAM up up
HTH,
