hi all,
i installed 4.3 recently after running 2.2.6 for ages - but now i've got a
>8Gb hd :) and i wanted to make use of it. in the past when i've copied my
installation to a second hd for backup i've been able to copy the bootloader
(?) from one to another with 'dd if=/dev/ad0 of=/dev/ad1 bs=446 count=1' but
now dd reports ( i think ) "invalid argument" - it only allows bs=512. is
this some sort of clean up of dd to make it work to spec? how do i get the
behaviour i'm after? or what is the proper way to just install the normal
freebsd type bootloader ( the F1,F2,F3,F4,F5 one). i tried 'fdisk -B' but
booting came up with "missing operating system". i guess i could just try
dd'ing the 512 bytes and then fdisk to put the pn table back - would that
work? however i'd still like to be able to separately backup my bootloader
and partition map into different files. any thoughts and directions are
welcome.
thanx, siegfried.
