Section 4.8 of the FAQ discusses how to capture the PBR for multibooting with dd:
# dd if=/dev/rwd0a of=openbsd.pbr bs=512 count=1 Two questions. * For stand-alone installations, is the PBR the same thing as the MBR? * More importantly, how can I use dd to access the MBR in a multibooted system of Vista & OpenBSD? Thanks for any insight.
