1.1 deraadt 19:
1.23 avsm 20: <p>
21: The powerpc port was first imported into OpenBSD at the end of 1996.
22: Portions of the kernel port came from the NetBSD/macppc port, and the
1.26 jufi 23: userland and build ports came from <a href="mailto:drahn@openbsd.org">Dale Rahn</a>.
1.1 deraadt 24:
1.3 fn 25: <p>
1.24 deraadt 26: Dale added ELF binary support, and then work with Per Fogelstrom
27: continued on general driver support for the next few releases.
1.23 avsm 28: Support was added for OpenFirmware, VI Power4e boards, MCG Powerstack
29: machines, Dec 21040, VGA terminal support, and so on.
1.12 deraadt 30:
31: <p>
1.23 avsm 32: In 1998, the focus shifted towards the Apple machines, and Dale Rahn
33: started work to make the range of iMacs and PowerMacs work with this port.
34: Due to this, official powerpc releases were not made for the 2.6 and 2.7
35: releases as work continued. A number of compiler loader issues were resolved,
36: a lot of iMac driver support was added, and compatibility with older systems
37: was withdrawn to fully concentrate on the Apple machines.
1.22 rahnds 38:
1.11 deraadt 39: <p>
1.23 avsm 40: And now, the 2.8 release at the end of 2000 will be including
41: an official powerpc port.

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

146: <p>
147: With multiple drives installed in the system, only certain drives can
148: be configured as an OpenBSD root drive. Any other configurations than
149: those below will not be able to properly detect which drive is the root
150: drive, and so any attempt with either prompt for a root drive, or fail.
151: <p>
152: <ul>
153: <li><tt>ultra0</tt> is always fine to use as an root drive.
154: <li><tt>ultra1</tt> is fine to use as a root disk (as long as <tt>ultra0</tt>
155: is a hard drive, not ATAPI).
156: <li>If no hard drive is located at <tt>ultra1</tt>, it is possible to use a
157: hard drive configured as <tt>ide1</tt> (zip bay) as root drive.
158: <li>It is not possible to use <tt>ide0</tt> (CD-ROM) as a root drive unless
159: no drives are connected to the Ultra IDE bus.
160: </ul>
161:
162: <h3><font color="#0000e0">X Resolution:</font></h3>
163: <p>
164: The current X server has no mechanism to change the resolution
165: of the display. To change the resolution, it is necessary to boot MacOS
166: and change to the desired resolution under MacOS. It will save that
167: resolution and OpenFirmware will boot in that resolution until connected
168: to a different monitor. The X server will run in whatever resolution
169: OpenFirmware boots in.
