1.23 avsm 123: <li>
1.34 horacio 124: Support for older PREP style machines has been removed; lack of
125: availability of the hardware and relatively slow speed compared to more
126: recent machines has contributed to this decision.
1.23 avsm 127: <li>
128: Apple PowerMac systems with a 601 processor or lack OpenFirmware
129: will likely never be supported.
130: <li>
131: At the current time, older OpenFirmware machines are not supported.
132: This is mostly due to lack of developer resources to work on the support
133: in addition to limited availability of hardware.
134: <li>On the device side, the following are recognized, but not supported:
135: <ul>
136: <li>Texas Instruments TSB12LV23 FireWire

1.32 drahn 140: <h3><font color="#0000e0">Shared HFS disks:</font></h3>
141: <p>
142: It is possible to share a disk between MacOS (OS X?) and OpenBSD.
143: MacOS must be installed first, and an Unused partition or other free
144: partition can then be used to install OpenBSD.
145: If a shared disk is to be used and be bootable, the bootloader "ofwboot"
146: must be copied onto the first HFS partition.
1.33 drahn 147: It is unknown if Openfirmware can load the OpenBSD bootloader from the
148: MacOS X FFS partition.
1.32 drahn 149: See INSTALL.powerpc for more details on how to install a shared disk.
150:
1.23 avsm 151: <h3><font color="#0000e0">Root Drive:</font></h3>
152: <p>
153: With multiple drives installed in the system, only certain drives can
154: be configured as an OpenBSD root drive. Any other configurations than
155: those below will not be able to properly detect which drive is the root
156: drive, and so any attempt with either prompt for a root drive, or fail.
157: <p>
158: <ul>
159: <li><tt>ultra0</tt> is always fine to use as an root drive.
160: <li><tt>ultra1</tt> is fine to use as a root disk (as long as <tt>ultra0</tt>
161: is a hard drive, not ATAPI).
162: <li>If no hard drive is located at <tt>ultra1</tt>, it is possible to use a
163: hard drive configured as <tt>ide1</tt> (zip bay) as root drive.
164: <li>It is not possible to use <tt>ide0</tt> (CD-ROM) as a root drive unless
165: no drives are connected to the Ultra IDE bus.
166: </ul>
167:
168: <h3><font color="#0000e0">X Resolution:</font></h3>
169: <p>
170: The current X server has no mechanism to change the resolution
171: of the display. To change the resolution, it is necessary to boot MacOS
172: and change to the desired resolution under MacOS. It will save that
173: resolution and OpenFirmware will boot in that resolution until connected
174: to a different monitor. The X server will run in whatever resolution
175: OpenFirmware boots in.

179: try one of the snapshots.
1.25 deraadt 180: For the powerpc architecture, <a href="ftp://ftp.openbsd.org/pub/OpenBSD/snapshots/powerpc">snapshots</a> are made available from time to time.

182: <h3><font color="#0000e0">History:</font></h3>
1.22 rahnds 183: <p>
1.32 drahn 184: The powerpc port was first imported into OpenBSD at the end of 1996.
185: Portions of the kernel came from the NetBSD/macppc port, and the
186: userland and build pieces came from
187: <a href="mailto:drahn@openbsd.org">Dale Rahn</a>.
1.22 rahnds 188:
1.32 drahn 189: <p>
190: Dale added ELF binary support, and then work with Per Fogelstrom
191: continued on general driver support for the next few releases.
192: Support was added for OpenFirmware, VI Power4e boards, MCG Powerstack
193: machines, DEC 21040, VGA terminal support, and so on.
194:
195: <p>
196: In 1998, the focus shifted towards the Apple machines, and Dale Rahn
197: started work to make the range of iMacs and PowerMacs work with this port.
198: Due to this, official powerpc releases were not made for the 2.6 and 2.7
199: releases as work continued. A number of compiler loader issues were resolved,
200: iMac driver support was added, and compatibility with older systems
201: was withdrawn to fully concentrate on the Apple machines.
202:
203: <p>
204: OpenBSD/powerpc 2.8 supported Apple hardware.
205:
206: <p>
207: For 2.9, powerpc has moved to UVM, this change has fixed the
208: corrupted shared library "pmap" bug that was rather pervasive for 2.8.
209:
210: <p>
211:
212: <h3><font color="#0000e0">Known Problems</font></h3>
213: The adb keyboard driver, on the iBook and Titanium Powerbook G4,
214: has problems such that some keystrokes can cause crashes. This
1.34 horacio 215: problem is mostly constrained to multiple keypresses involving the
216: <code>Fn</code> key. Also note that <CTRL><CMD><POWER> will
217: reset the machine.
1.32 drahn 218: <p>
219: USB Hot-Plug detection problems exist on many of the newer systems.
220: This problem only exists with the root hub on systems which have only
1.33 drahn 221: one port per root hub, G4 tower systems, PowerBook G4, newer iMacs.
222: These systems configure with both ohci0 and ohci1.
