120: <a name="#unsup"><h3><font color=#0000e0>Unsupported Hardware:</font></h3></a>
121: <ul>
122: <li>
123: Apple PowerMac systems with a 601 processor or lack OpenFirmware
124: will likely never be supported.
125: <li>
126: At the current time, older OpenFirmware machines are not supported.
127: This is mostly due to lack of developer resources to work on the support
128: in addition to limited availability of hardware.
129: <li>On the device side, the following are recognized, but not supported:
130: <ul>
131: <li>Texas Instruments TSB12LV23 FireWire
132: </ul>
133: </ul>
134:
135: <h3><font color="#0000e0">Shared HFS disks:</font></h3>
136: <p>
137: It is possible to share a disk between MacOS (OS X?) and OpenBSD.
138: MacOS must be installed first, and an Unused partition or other free
139: partition can then be used to install OpenBSD.
140: If a shared disk is to be used and be bootable, the bootloader "ofwboot"
141: must be copied onto the first HFS partition.
142: It is unknown if Openfirmware can load the OpenBSD bootloader from the
143: MacOS X FFS partition.
1.2 ! brad 144: See INSTALL.macppc for more details on how to install a shared disk.
1.1 brad 145:
146: <h3><font color="#0000e0">Root Drive:</font></h3>
147: <p>
148: With multiple drives installed in the system, only certain drives can
149: be configured as an OpenBSD root drive. Any other configurations than
150: those below will not be able to properly detect which drive is the root
151: drive, and so any attempt with either prompt for a root drive, or fail.
152: <p>
153: <ul>
154: <li><tt>ultra0</tt> is always fine to use as an root drive.
155: <li><tt>ultra1</tt> is fine to use as a root disk (as long as <tt>ultra0</tt>
156: is a hard drive, not ATAPI).
157: <li>If no hard drive is located at <tt>ultra1</tt>, it is possible to use a
158: hard drive configured as <tt>ide1</tt> (zip bay) as root drive.
159: <li>It is not possible to use <tt>ide0</tt> (CD-ROM) as a root drive unless
160: no drives are connected to the Ultra IDE bus.
161: </ul>
162:
163: <h3><font color="#0000e0">X Resolution:</font></h3>
164: <p>
165: The current X server has no mechanism to change the resolution
166: of the display. To change the resolution, it is necessary to boot MacOS
167: and change to the desired resolution under MacOS. It will save that
168: resolution and OpenFirmware will boot in that resolution until connected
169: to a different monitor. The X server will run in whatever resolution
170: OpenFirmware boots in.

173: <p>If you are looking for to test new pre-release features, you can
1.2 ! brad 174: try one of the snapshots.
! 175: For the macppc architecture, <a href="ftp://ftp.openbsd.org/pub/OpenBSD/snapshots/macppc">snapshots</a> are made available from time to time.
1.1 brad 176:
177: <h3><font color="#0000e0">History:</font></h3>
178: <p>
179: The powerpc port was first imported into OpenBSD at the end of 1996.
180: Portions of the kernel came from the NetBSD/macppc port, and the
181: userland and build pieces came from
182: <a href="mailto:drahn@openbsd.org">Dale Rahn</a>.
183:
184: <p>
185: Dale added ELF binary support, and then work with Per Fogelstrom
186: continued on general driver support for the next few releases.
187: Support was added for OpenFirmware, VI Power4e boards, MCG Powerstack
188: machines, DEC 21040, VGA terminal support, and so on.
189:
190: <p>
191: In 1998, the focus shifted towards the Apple machines, and Dale Rahn
192: started work to make the range of iMacs and PowerMacs work with this port.
193: Due to this, official powerpc releases were not made for the 2.6 and 2.7
194: releases as work continued. A number of compiler loader issues were resolved,
195: iMac driver support was added, and compatibility with older systems
196: was withdrawn to fully concentrate on the Apple machines.
197:
198: <p>
199: OpenBSD/powerpc 2.8 supported Apple hardware.
200:
201: <p>
202: For 2.9, powerpc has moved to UVM, this change has fixed the
203: corrupted shared library "pmap" bug that was rather pervasive for 2.8.
204:
205: <p>
1.2 ! brad 206: For 3.0, the powerpc port has been renamed to macppc.

1.1 brad 209:
210: <h3><font color="#0000e0">Known Problems</font></h3>
211: The adb keyboard driver, on the iBook and Titanium Powerbook G4,
212: has problems such that some keystrokes can cause crashes. This
213: problem is mostly constrained to multiple keypresses involving the
214: <code>Fn</code> key. Also note that <CTRL><CMD><POWER> will
215: reset the machine.
216: <p>
217: USB Hot-Plug detection problems exist on many of the newer systems.
218: This problem only exists with the root hub on systems which have only
219: one port per root hub, G4 tower systems, PowerBook G4, newer iMacs.
220: These systems configure with both ohci0 and ohci1.
