Need your help!!! I have a SPARC Ultra 10 machine running Solaris 10, it was using static ip address, recently I changed the config from static ip to dynamic ip which connected to a gateway, added the default gateway in routine table, after the changes I rebooted machine couple times, and everything works normal. It got his own ip and could communicate with other machine on the small network. But all of sudden, after I tried to reboot it, it was hang at the message "Use is subject to license terms." STOP+A couldn't bring me to ok prompt, the only way I have to do is power it donw, then power it up, at the ok prompt, I typed boot -v, the following is the output: ok boot -v Boot device: /pci@1f,0/pci@1,1/ide@3/disk@0,0 File and args: -v The boot filesystem is logging. The ufs log is empty and will not be used.

But if I test on qfe@0,1 when I connected it to the switch, the output was ok test /pci@1f,0/pci@1/pci@3/SUNW,qfe@0,1 qfe@0,1 register test --- succeeded.
