I had disabled 905C's network boot feature, when I asked.
But my mother board is too old, so after disabling it, the
905C was still trying to boot from the network.  I didn't
connect a monitor, so I couldn't understand why it didn't
work.  Then, along you suggestion, I tried all.  Then, I
found out that I have to disable whole boot menu for my old
PC.  After that, it works fine.  Thanks a lot.
