1.23 avsm 20: <p>
21: The powerpc port was first imported into OpenBSD at the end of 1996.
1.30 brad 22: Portions of the kernel came from the NetBSD/macppc port, and the
23: userland and build pieces came from
24: <a href="mailto:drahn@openbsd.org">Dale Rahn</a>.

1.3 fn 26: <p>
1.24 deraadt 27: Dale added ELF binary support, and then work with Per Fogelstrom
28: continued on general driver support for the next few releases.
1.23 avsm 29: Support was added for OpenFirmware, VI Power4e boards, MCG Powerstack
1.30 brad 30: machines, DEC 21040, VGA terminal support, and so on.
1.12 deraadt 31:
32: <p>
1.23 avsm 33: In 1998, the focus shifted towards the Apple machines, and Dale Rahn
34: started work to make the range of iMacs and PowerMacs work with this port.
35: Due to this, official powerpc releases were not made for the 2.6 and 2.7
36: releases as work continued. A number of compiler loader issues were resolved,
1.30 brad 37: iMac driver support was added, and compatibility with older systems
1.23 avsm 38: was withdrawn to fully concentrate on the Apple machines.

1.8 rahnds 132: <ul>
1.23 avsm 133: <li>
134: Support for older PREP style machines have been removed; lack of availability
135: of the hardware and relatively slow speed compared to more recent machines has
136: contributed to this decision.
137: <li>
138: Apple PowerMac systems with a 601 processor or lack OpenFirmware
139: will likely never be supported.
140: <li>
141: At the current time, older OpenFirmware machines are not supported.
142: This is mostly due to lack of developer resources to work on the support
143: in addition to limited availability of hardware.
144: <li>On the device side, the following are recognized, but not supported:
145: <ul>
146: <li>Texas Instruments TSB12LV23 FireWire

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.
