Just wondering if FreeBSD has an equivalent to the 'fdisk /mbr' command in DOS (which installs a standard, simple bootloader in the MBR that chainloads from the active partition).
The boot0cfg man page
but all that seems to do is replace the current bootloader with the one that was present before you installed FreeBSD. And since the bootloader that was present before I installed FreeBSD was in fact the FreeBSD bootloader, this fdisk command effectively does nothing.
By the way, the reason I want to revert to the simple bootloader is that FreeBSD is the only OS on this computer, so I have no need for an interactive bootloader.
