Before you begin, you should decide if OpenBSD is to be installed
on the whole disk or share the disk with Mac OS.
For stand-alone (No Mac OS installed) or dedicated disks, the MBR
installation method should be chosen and no additional prep is necessary.
If the disk is to be shared with Mac OS, a partition must be preallocated
by the Mac OS partition editor and Mac OS installed to the proper partition.
This expects that the HFS partition will be the first partition on
the disk, and then the OpenBSD partition will follow.
This may require the disk be reformatted using the "Drive Setup" application
and reinstalled under Mac OS.

At this time, the system can be installed from the supplied
CD-ROM boot image, by network loading the bootloader, or loading
the bootloader and kernel from an HFS partition.
Once the bootloader is installed on the local hard drive, the
system can boot from it. OpenBSD may share a drive with Mac OS
if the process is followed carefully. Currently it is
necessary to use Open Firmware commands to dual boot between
OS's, or multiple drives may be used with each OS owning drive(s).
It is also possible on some newer models to set up the system
to auto boot OpenBSD and if Mac OS is desired, choose it using
the firmware boot selector by holding down the <option> key
during reboot and selecting the Mac OS Disk icon.
(Refer to "Preparing your System for OpenBSD Installation" above
for information on how to access and boot from Open Firmware.)

Disks on OpenBSD/MACHINE are partitioned either using Apple-style
HFS partitions, or MBR partitions.
OpenBSD/MACHINE can share a disk with Mac OS or Mac OS X by using
an HFS partitioned disk. For proper layout, the disk should be
partitioned with Mac OS or Mac OS X first with unused space or a
spare partition where OpenBSD can be installed.
The installation program will ask you whether you intend to use
HFS or MBR partitions.
HFS partitioning:
HFS partition tables are edited with pdisk(8). The most
common operation, and the example presented here, deals
with the conversion of an existing partition into one usable
by OpenBSD.
Before editing, the partition table may look like the
following:
#: type name length base ( size )
1: Apple_partition_map Apple 63 @ 1
2: Apple_Driver43*Macintosh 54 @ 64
3: Apple_Driver43*Macintosh 74 @ 118
4: Apple_Driver_ATA*Macintosh 54 @ 192
5: Apple_Driver_ATA*Macintosh 74 @ 246
6: Apple_FWDriver Macintosh 200 @ 320
7: Apple_Driver_IOKit Macintosh 512 @ 520
8: Apple_Patches Patch Partition 512 @ 1032
9: Apple_HFS untitled 2142310 @ 1544 ( 1.0G)
10: Apple_HFS untitled 2 4120589 @ 2143854 ( 2.0G)
11: Unused untitled 3 6330517 @ 6264443 ( 3.0G)
After editing the table, it should look like:
#: type name length base ( size )
1: Apple_partition_map Apple 63 @ 1
2: Apple_Driver43*Macintosh 54 @ 64
3: Apple_Driver43*Macintosh 74 @ 118
4: Apple_Driver_ATA*Macintosh 54 @ 192
5: Apple_Driver_ATA*Macintosh 74 @ 246
6: Apple_FWDriver Macintosh 200 @ 320
7: Apple_Driver_IOKit Macintosh 512 @ 520
8: Apple_Patches Patch Partition 512 @ 1032
9: Apple_HFS untitled 2142310 @ 1544 ( 1.0G)
10: Apple_HFS untitled 2 4120589 @ 2143854 ( 2.0G)
11: OpenBSD OpenBSD 6330517 @ 6264443 ( 3.0G)
This will likely be different based on the number of
partitions created on the disk by the Apple partition editor.
It is _VERY_ important to not change the start, sizes, or
types of partitions other than the ones that are to be used
by OpenBSD, including the Apple_Driver.* and
Apple_partition_map.

The installation program will ask you if you want to use
the whole disk for OpenBSD. If you don't need to or don't
intend to share the disk with other operating systems,
answer `y' here. The installation program will then create
a single MBR partition spanning the whole disk, dedicated
to OpenBSD.
Otherwise, fdisk(8) will be invoked to let you to edit
your MBR partitioning. The current MBR partitions defined
will be displayed and you will be allowed to modify them,
add new partitions, and change which partition to boot from
by default.
After your OpenBSD MBR partition has been setup, the real
partition setup can follow.
OpenBSDInstallPart5({:-
If you have DOS or Linux partitions defined on the disk, these
will usually show up as partition 'i', 'j' and so on.-:})
If you chose to use HFS partitioning to share the disk with MacOS,
OpenBSD will be unable to install the bootloader into the HFS(+)
partition to boot OpenBSD; it will be necessary to copy 'ofwboot'
from the installation media into the first HFS(+) partition using
Mac OS or Mac OS X.
If the disk is partitioned using MBR, the bootloader will be
automatically installed if you setup a small (a few MB) MSDOS
partition as position `i' in the label.
