1.34 ! horacio 112: Support for older PREP style machines has been removed; lack of
! 113: availability of the hardware and relatively slow speed compared to more
! 114: recent machines has contributed to this decision.
1.23 avsm 115: <li>
116: Apple PowerMac systems with a 601 processor or lack OpenFirmware
117: will likely never be supported.
118: <li>
119: At the current time, older OpenFirmware machines are not supported.
120: This is mostly due to lack of developer resources to work on the support
121: in addition to limited availability of hardware.
122: <li>On the device side, the following are recognized, but not supported:
123: <ul>
124: <li>Texas Instruments TSB12LV23 FireWire

1.32 drahn 128: <h3><font color="#0000e0">Shared HFS disks:</font></h3>
129: <p>
130: It is possible to share a disk between MacOS (OS X?) and OpenBSD.
131: MacOS must be installed first, and an Unused partition or other free
132: partition can then be used to install OpenBSD.
133: If a shared disk is to be used and be bootable, the bootloader "ofwboot"
134: must be copied onto the first HFS partition.
1.33 drahn 135: It is unknown if Openfirmware can load the OpenBSD bootloader from the
136: MacOS X FFS partition.
1.32 drahn 137: See INSTALL.powerpc for more details on how to install a shared disk.
138:
1.23 avsm 139: <h3><font color="#0000e0">Root Drive:</font></h3>
140: <p>
141: With multiple drives installed in the system, only certain drives can
142: be configured as an OpenBSD root drive. Any other configurations than
143: those below will not be able to properly detect which drive is the root
144: drive, and so any attempt with either prompt for a root drive, or fail.
145: <p>
146: <ul>
147: <li><tt>ultra0</tt> is always fine to use as an root drive.
148: <li><tt>ultra1</tt> is fine to use as a root disk (as long as <tt>ultra0</tt>
149: is a hard drive, not ATAPI).
150: <li>If no hard drive is located at <tt>ultra1</tt>, it is possible to use a
151: hard drive configured as <tt>ide1</tt> (zip bay) as root drive.
152: <li>It is not possible to use <tt>ide0</tt> (CD-ROM) as a root drive unless
153: no drives are connected to the Ultra IDE bus.
154: </ul>
155:
156: <h3><font color="#0000e0">X Resolution:</font></h3>
157: <p>
158: The current X server has no mechanism to change the resolution
159: of the display. To change the resolution, it is necessary to boot MacOS
160: and change to the desired resolution under MacOS. It will save that
161: resolution and OpenFirmware will boot in that resolution until connected
162: to a different monitor. The X server will run in whatever resolution
163: OpenFirmware boots in.

170: <h3><font color="#0000e0">History:</font></h3>
1.22 rahnds 171: <p>
1.32 drahn 172: The powerpc port was first imported into OpenBSD at the end of 1996.
173: Portions of the kernel came from the NetBSD/macppc port, and the
174: userland and build pieces came from
175: <a href="mailto:drahn@openbsd.org">Dale Rahn</a>.
1.22 rahnds 176:
1.32 drahn 177: <p>
178: Dale added ELF binary support, and then work with Per Fogelstrom
179: continued on general driver support for the next few releases.
180: Support was added for OpenFirmware, VI Power4e boards, MCG Powerstack
181: machines, DEC 21040, VGA terminal support, and so on.
182:
183: <p>
184: In 1998, the focus shifted towards the Apple machines, and Dale Rahn
185: started work to make the range of iMacs and PowerMacs work with this port.
186: Due to this, official powerpc releases were not made for the 2.6 and 2.7
187: releases as work continued. A number of compiler loader issues were resolved,
188: iMac driver support was added, and compatibility with older systems
189: was withdrawn to fully concentrate on the Apple machines.
190:
191: <p>
192: OpenBSD/powerpc 2.8 supported Apple hardware.
193:
194: <p>
195: For 2.9, powerpc has moved to UVM, this change has fixed the
196: corrupted shared library "pmap" bug that was rather pervasive for 2.8.
197:
198: <p>
199:
200: <h3><font color="#0000e0">Known Problems</font></h3>
201: The adb keyboard driver, on the iBook and Titanium Powerbook G4,
202: has problems such that some keystrokes can cause crashes. This
1.34 ! horacio 203: problem is mostly constrained to multiple keypresses involving the
! 204: <code>Fn</code> key. Also note that <CTRL><CMD><POWER> will
! 205: reset the machine.
1.32 drahn 206: <p>
207: USB Hot-Plug detection problems exist on many of the newer systems.
208: This problem only exists with the root hub on systems which have only
1.33 drahn 209: one port per root hub, G4 tower systems, PowerBook G4, newer iMacs.
210: These systems configure with both ohci0 and ohci1.
