Thank you very much for your kind reply. Sorry for late response, since other urgent things these days.
The hardware installed is Intel Core i7 based desktop, and I tried to use the debugger at the boot, but the machines has no PS/2 port and the USB keyboard can not work at that time, so I have no chance to go further, so I stop to upgrade my system now. BTW, the machine is running Nevada b95 now, and I tried to use liveupgrade to upgrade it to b108, it's successful upgrading, but after reboot, it's still hang at the same place as try to boot with DVD. Thanks, Wesley -- This message posted from opensolaris.org
