1.8 rahnds 121: <ul>
1.23 avsm 122: <li>
1.34 horacio 123: Support for older PREP style machines has been removed; lack of
124: availability of the hardware and relatively slow speed compared to more
125: recent machines has contributed to this decision.
1.23 avsm 126: <li>
127: Apple PowerMac systems with a 601 processor or lack OpenFirmware
128: will likely never be supported.
129: <li>
130: At the current time, older OpenFirmware machines are not supported.
131: This is mostly due to lack of developer resources to work on the support
132: in addition to limited availability of hardware.
133: <li>On the device side, the following are recognized, but not supported:
134: <ul>
135: <li>Texas Instruments TSB12LV23 FireWire

1.32 drahn 139: <h3><font color="#0000e0">Shared HFS disks:</font></h3>
140: <p>
141: It is possible to share a disk between MacOS (OS X?) and OpenBSD.
142: MacOS must be installed first, and an Unused partition or other free
143: partition can then be used to install OpenBSD.
144: If a shared disk is to be used and be bootable, the bootloader "ofwboot"
145: must be copied onto the first HFS partition.
1.33 drahn 146: It is unknown if Openfirmware can load the OpenBSD bootloader from the
147: MacOS X FFS partition.
1.32 drahn 148: See INSTALL.powerpc for more details on how to install a shared disk.
149:
1.23 avsm 150: <h3><font color="#0000e0">Root Drive:</font></h3>
151: <p>
152: With multiple drives installed in the system, only certain drives can
153: be configured as an OpenBSD root drive. Any other configurations than
154: those below will not be able to properly detect which drive is the root
155: drive, and so any attempt with either prompt for a root drive, or fail.
156: <p>
157: <ul>
158: <li><tt>ultra0</tt> is always fine to use as an root drive.
159: <li><tt>ultra1</tt> is fine to use as a root disk (as long as <tt>ultra0</tt>
160: is a hard drive, not ATAPI).
161: <li>If no hard drive is located at <tt>ultra1</tt>, it is possible to use a
162: hard drive configured as <tt>ide1</tt> (zip bay) as root drive.
163: <li>It is not possible to use <tt>ide0</tt> (CD-ROM) as a root drive unless
164: no drives are connected to the Ultra IDE bus.
165: </ul>
166:
167: <h3><font color="#0000e0">X Resolution:</font></h3>
168: <p>
169: The current X server has no mechanism to change the resolution
170: of the display. To change the resolution, it is necessary to boot MacOS
171: and change to the desired resolution under MacOS. It will save that
172: resolution and OpenFirmware will boot in that resolution until connected
173: to a different monitor. The X server will run in whatever resolution
174: OpenFirmware boots in.

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