From the top of my head, dd if=/dev/wd0s1a of=root.iso dd if=/dev/wd0s1f of=usr.iso .... It may/(not) be necessary to specify a block size but that is for you to investigate ;-) Then ftp the .iso files to the other box and do something like vnconfig /dev/vn0c root.iso mount /dev/vn0c /usr/mnt [ yeah, the vnconfig page says a lot about these so if I make a mistake..] However, if I were you, I'd move the disk onto the other box and connect it as slave then do something like mkdir /usr/rootmnt mkdir /usr/usrmnt Then mount /dev/wd1s1a /usr/rootmnt ...something along those lines, and do what I want.. Sorry I am a bit sketch but I hope it gives you the kickstart.. -Wash -- Odhiambo Washington <wash@wananchi.com> "The box said 'Requires Wananchi Online Ltd. www.wananchi.com Windows 95, NT, or better,' Tel: 254 2 313985-9 Fax: 254 2 313922 so I installed FreeBSD."
