При использовании FreeBSD livefs диска выбираем пункты меню:

"Fixit" -> CDROM/DVD -> Alt-F4

При использовании frenzy livecd в процессе загрузки указываем опцию

nohdd

Fixit# ifconfig rl0 inet 10.10.106.X/24
Fixit# ping 10.10.106.Z
...

Добавляем упоминание сервиса rsh в файл /etc/services

Fixit# cat >> /etc/services
shell 514/tcp
<Ctrl>-D

Используем sysinstall вместо утилит fdisk, bootmgr, bsdlabel и newfs
