Apple systems have two methods to label/partition a boot disk.
Either the disk can be partitioned with Apple HFS partition tools to contain
an "Unused" partition, or without any MacOS tools, the disk can be labled
using an MBR partition table.
If the HFS (DPME) partition table is used, after the disk is partitioned with
the Apple software, the "Unused" section must be changed to type "OpenBSD" name
"OpenBSD" using the pdisk tool contained on this ramdisk. The disklabel can
then be edited normally.
WARNING: the MBR partitioning code will HAPPILY overwrite/destroy any HFS
partitions on the disk, including the partition table.
Choose the MBR option carefully, knowing this fact.

Disk partition sizes and offsets are in sector (most likely 512 bytes) units.
You may set these size/offset pairs on cylinder boundaries
(the number of sector per cylinder is given in )
(the `sectors/cylinder' entry, which is not shown here)
Also, you *must* make sure that the 'i' partition points at the MSDOS
partition that will be used for booting. The 'c' partition shall start
at offset 0 and include the entire disk. This is most likely correct when
you see the default label in the editor.
Do not change any parameters except the partition layout and the label name.
[Here is an example of what the partition information may look like.]
10 partitions:
# size offset fstype [fsize bsize cpg]
a: 120832 10240 4.2BSD 1024 8192 16 # (Cyl. 11*- 142*)

As with anything which modifies your disk's contents, this program can cause
SIGNIFICANT data loss, and you are advised to make sure your data is backed
up before beginning the installation process.
Default answers are displayed in brackets after the questions. You can hit
Control-C at any time to quit, but if you do so at a prompt, you may have
to hit return. Also, quitting in the middle of installation may leave your
system in an inconsistent state. If you hit Control-C and restart the
install, the install program will remember many of your old answers.
