Hi all!

I'm quite a newbie in administration tasks, so maybe this is a trivial
question ;-)

The fact is that I boot from cdrom to install an application on a SunFire
280R,
I'm using a laptop connected to serial port.
The installation proceeds to format the system and install system files.
Then, system is rebooted but for some reason root partition is not mounted,
and sytem is restarted again and again showing always the message below.

Do you know how can I break this endless loop?

Thanks in advance
