- PowerMac G4
(PCI Graphics? - untested but should work)
- PowerMac G4 (AGP Graphics)
- PowerMac G4 (Digital Audio)
- PowerMac G4 (QuickSilver)
- PowerMac G4 (QuickSilver 2002)
- PowerMac Dual G4
- PowerMac G4 Cube
- iMac Rev A
- iMac Rev B
- iMac Rev C
- iMac DV
- iMac DV+
- LCD iMac (new with 3.1)
- PowerBook G3 (FireWire)
- PowerBook G4
- iBook
- iBook2 (problems with Combo drive thought to be fixed in 3.1)
- Xserve (currently only running on serial console with video card removed)
- StarMax (development in progress)
- others... (development in progress)
To help us improve the accuracy of this list, PLEASE
send your dmesg after installation
to dmesg@OpenBSD.org.
Multiboot/Shared HFS disks:
Having OpenBSD multiboot, or share, a disk with OS X/MacOS 9
is possible as long as the disk is first partitioned with the
macOS utility, Drive Setup (MacOS9) or System Disk
Utility (Mac OS X). Unallocated space or a
no longer desired partition must be left for OpenBSD's use.
Since OpenBSD is only able to boot from HFS (not MacOS X UFS) partitions
the first partition must formated HFS(+), not UFS, to be able to boot
OpenBSD.
See INSTALL.macppc for more details on how to install a shared disk.
Stand-alone (no MacOS present) installation is also supported.
Root Drive:
Modern MacPPC systems have two IDE interfaces (called Ultra and IDE), each of
which can have two devices on them (ultra0, ultra1, ide0, ide1).
When multiple drives are present in the system, there are limitations
of which drives can be configured as the OpenBSD root drive.
Invalid configurations will not be able to properly
detect which drive is the root drive, so any attempt will either
prompt for a root drive or fail.
- ultra0 is always a valid root drive.
- ultra1 is valid as a root disk, as long as ultra0
is a hard drive, not a non-hard disk ATAPI device).
- ide1 (Zip drive bay) is valid as a root disk if no hard drive is
located at ultra1,
- ide0 (CD-ROM) is valid as a root drive only if no hard
drives are connected to the Ultra bus.
X Window System:
XFree86 Version 4.2.0 is supported on all MacPPC systems, however
only the ATI graphics adapters are supported by an accelerated
X server at the current time.
The nVidia accelerated X server does not currently work, however nVidia
(and ATI) cards can be used by X in framebuffer (unaccelerated) mode,
at the boot resolution and color depth using the wsfb driver (installed by
default).
Directions on enabling the accelerated X server is
in the /usr/X11R6/README file on the installed system.
Known Problems
- Laptop systems may power off within 2-5 minutes if the lid is closed
while running from battery.
- Older iMacs can have a problem with the USB keyboard driver where
the first key pressed after boot will repeat endlessly. The workaround
is to press <SHIFT> first or to disconnect and reconnect the USB mouse
after the problem has occurred.
Other Features
- <CTRL><CMD><POWER> on ADB (not USB) keyboards
will reset the computer.

- Other Devices
- Serial Ports: While the modern PowerMacintosh series has no external
standard serial ports, many have an on-board modem which can be
removed and replaced with an adapter (several manufacturers of these exist)
which will produce a standard (and supported) serial port.
- Firewire device now probes and is configured, but no devices will attach
on the firewire bus, yet.
- Backlight on lcd devices can be controlled thru the brightness control
keys on ADB (laptop) keyboards, or thru 'wsconsctl -w display.brightness=xx'
(0 - 100) and 'wsconsctl -w display.backlight=xx' (0 or 100)
Unsupported Hardware:
- Older Apple PowerMac systems with a 601 processor and those that
lack OpenFirmware are not supported.
- Older OpenFirmware machines are not currently supported.
This is mostly due to lack of developer resources and limited
availability of hardware.
- Built-in modems on most machines are not supported. In many systems,
the serial port the modem is attached to is supported, but the modem
itself is not supported.
- Newer PowerBooks have an internal modem attached as a USB device, these
are not supported.
- The new 'digital audio' subsystem on iBooks and newer PBG4, G4 and iMacs
is not supported.
- Sleep/Suspend is not supported.
If you are looking for or are willing to test new pre-release
features, you can try using a
snapshot which are made available
on the FTP
sites from time to time.
