Hi... on freebsd-hackers, Alfred Perlstein posted a method that allows boot-disk-less installation... but it requires mdconfig, a 5.1 utility...
is there a method to do this under 4.8? it seems to me that the job performed by md0 could be done with vn0 e.g. do # ls /dev/vn* if empty do # cd /dev # ./MAKEDEV vn0 # ./MAKEDEV vn1 # vnconfig vn0 /path/to/freebsd/4.9.iso # mount_cd9660 /dev/vn0c /path/to/freebsd4.9 or however you access the freebsd install iso disk the point being to get access to the /floppies/boot.flp image on the cdrom # vnconfig vn1 /path/to/freebsd4.9/floppies/boot.flp # mkdir /bootfloppy # mount_mfs /dev/vn1c /bootfloppy/ # cp /bootfloppy/kernel.gz /ikernel.gz # cp /bootfloppy/mfsroot.gz /mfsroot.gz then reboot as described... I am about to try this out... wish me luck!
