You answered one part of a two-part question.

Do I have to "relabel" slices as bootable in /stand/sysinstall or just use `fdisk -B [device containing Fbsd OS here]` ? > boot0cfg should be save. If you give the wrong argument to fdisk, you can destroy the partition information. > <mike > Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ > Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information. I don't know what I'm doing, and the instructions for boot0cfg and fdisk are NOT COMPLETE (the handbook is very lacking in this department too). When I recently got the boot0cfg command to run, it told me "Device busy." To reiterate what I am trying to do -- My computer has just one HD, but (among others) the two partitions listed below: /dev/ad0s2a on / (ufs, local) /dev/ad0s1 on /msdos (msdos, local) IS there a command to use the standard MBR manager (no F1, F2, etc.. menu) *and* boot directly, automatically to /dev/ad0s2a but keep /dev/ad0s1 (/msdos) mountable?
