If anyone else runs into the same problem, it would probably be a
help if they could save the output from the following script before
proceeding:
#!/bin/sh
DRIVE=da0
SLICE=s1
fdisk ${DRIVE}
disklabel ${DRIVE}
dd if=/dev/r${DRIVE} count=1
dd if=/dev/r${DRIVE}${SLICE} count=17
However, the problem in Julian's case is most likely that fdisk -b
writes a completely standard MBR which effectively assumes that
the drive being booted from is BIOS drive 0x80 (drive 0). You have
to have a boot manager (or some kind of non-standard MBR) on
higher-numbered drives in order to boot from them.
