What you just did was zero out the bootcode portion of the MBR (which is fine if you don't multiboot) and initialize the partition table of the MBR to read just one FreeBSD slice covering the entire disk (also fine if you only had one FreeBSD partition there to begin with). What this means is that any other slices you had on the disk will be gone. I don't know what disk layout you had, but something tells me that you may have erased /usr, /var and /tmp (if you used the default fdisk layout when installing FreeBSD, that is). I'm no expert, but I think this _can_ lead to complications. -- Henrik W Lund
