In a previous mail in this thread I said: " I just tried 'fdisk -B ad0',
and it has correctly 'demoted' the boot manager to just go ahead and
boot the first partition."
The -b argument to fdisk will allow you to specify one of the
alternative boot codes, but the one you want is /boot/mbr, which is the
default value for -b. Therefore, you do not need to specify it when
typing the command.
As Mike said above, and as I confirmed, this should do the trick for
you:
# fdisk -B ad0
Alternatively, you can do EXACTLY the same thing by typing:
# fdisk -B -b /boot/mbr ad0
Mike used "da0" because his is a SCSI disk, but yours is IDE, so "ad0"
is the way to go.
If you need to set the active partition, use:
# fdisk -a ad0

Patrick O'Reilly.
