Dear all,

When I am sending the magic packet to the remote machine on LAN, it receive the magic packet, that I can see that it's power lights are on. But on the screen it only show a blinking cursor blinking on it for many hours. But do not load the POST process/boot into the operating system. However an other machine is booting fine. Both machines have same configurations.

Please help.

Thanks in advance.
