One way, not necessarily the best way, if you want dualboot, is
* boot the OS X installation disk.
* Partition the disk, leaving a FAT32 partition for OpenBSD. Using
FAT32 is way to make a physical partition. (This may not be necessary.)
* Install OS X.
* Install rEFIt
http://refit.sourceforge.net/
Make sure to run
/efi/refit/enable-always.sh
* boot the OpenBSD installation cd, change the FAT32 partition to
OpenBSD and use all of it.
* reboot, and use the rEFIt menu to choose the Start Partitioning Tool
option to sync the MBR.
* choose the OpenBSD icon and wait a bit. I don't know what it's doing,
but it won't go anywhere.
* forcibly reboot. Now you can choose OS X or OpenBSD upon startup. OS
X will be the default, unless you change rEFIt's settings.
YMMV
It's possible to set triple boot with linux also, but watch out that
grub doesn't mess with the bootloader when you do your next update. If
that happens then you can set grub to include something like this:
## OpenBSD
title OpenBSD
root (hd1,1)
# or where ever the root was
makeactive
chainloader +1
/Lars
