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>.

1.24 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.

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1.23 avsm 38: was withdrawn to fully concentrate on the Apple machines.

1.30 ! brad 41: As of the 2.8 release there will be official releases for the powerpc port

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

1.23 avsm 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.
