According to one suggestion I changed ethernet cable. I also connected
both servers to one, separated hub to avoid overloaded network.
But now I have following:
Timeout waiting for ARP/RARP packet...

I found description of the problem in "Advanced Installation Guide".
I have following:
# grep bootparams /etc/nsswitch.conf
bootparams: files
# cat /etc/bootparams
* install_config=gamon:/jumpstart

Do I need something else in the file ?
