Thanks to all who have helped. I've proceeded a bit further. My monitor/keyboard/mouse were connected via a Aten monitor switch which somehow swallowed the first key presses. I think the system now waits at Grub for the input. I still get the screen msg"switch to 90 khz/60 Hz". A second screen only outputs 'Out of range'. I get now the Boot menu, but I don't see the DVD drive. When I press 'Arrow down' and Enter after the beep I get more messages from the system boot. It seems that the first network interface 'eth0' gets an address via dhcp from my router. Then I geta msg about samba started and afterwards the system hangs. I think it will now configure the second network interface. Would it make sense to remove the network card for the second interface (only the first one is on the motherboard)? Any more tips for me? Since it's a bit late I will wait until tomorrow. Kind regards, Hans
