108: Support for older PREP style machines have been removed; lack of availability
109: of the hardware and relatively slow speed compared to more recent machines has
110: contributed to this decision.
111: <li>
112: Apple PowerMac systems with a 601 processor or lack OpenFirmware
113: will likely never be supported.
114: <li>
115: At the current time, older OpenFirmware machines are not supported.
116: This is mostly due to lack of developer resources to work on the support
117: in addition to limited availability of hardware.
118: <li>On the device side, the following are recognized, but not supported:

! 125: <p>
! 126: It is possible to share a disk between MacOS (OS X?) and OpenBSD.
! 127: MacOS must be installed first, and an Unused partition or other free
! 128: partition can then be used to install OpenBSD.
! 129: If a shared disk is to be used and be bootable, the bootloader "ofwboot"
! 130: must be copied onto the first HFS partition.
! 131: See INSTALL.powerpc for more details on how to install a shared disk.
! 132:
1.23 avsm 133: <h3><font color="#0000e0">Root Drive:</font></h3>
134: <p>
135: With multiple drives installed in the system, only certain drives can
136: be configured as an OpenBSD root drive. Any other configurations than
137: those below will not be able to properly detect which drive is the root
138: drive, and so any attempt with either prompt for a root drive, or fail.
139: <p>
140: <ul>
141: <li><tt>ultra0</tt> is always fine to use as an root drive.
142: <li><tt>ultra1</tt> is fine to use as a root disk (as long as <tt>ultra0</tt>
143: is a hard drive, not ATAPI).
144: <li>If no hard drive is located at <tt>ultra1</tt>, it is possible to use a
145: hard drive configured as <tt>ide1</tt> (zip bay) as root drive.
146: <li>It is not possible to use <tt>ide0</tt> (CD-ROM) as a root drive unless
147: no drives are connected to the Ultra IDE bus.

150: <h3><font color="#0000e0">X Resolution:</font></h3>
151: <p>
152: The current X server has no mechanism to change the resolution
153: of the display. To change the resolution, it is necessary to boot MacOS
154: and change to the desired resolution under MacOS. It will save that
155: resolution and OpenFirmware will boot in that resolution until connected
156: to a different monitor. The X server will run in whatever resolution
157: OpenFirmware boots in.

! 164: <h3><font color="#0000e0">History:</font></h3>
1.22 rahnds 165: <p>
1.32 ! drahn 166: The powerpc port was first imported into OpenBSD at the end of 1996.
! 167: Portions of the kernel came from the NetBSD/macppc port, and the
! 168: userland and build pieces came from
! 169: <a href="mailto:drahn@openbsd.org">Dale Rahn</a>.
1.22 rahnds 170:
1.32 ! drahn 171: <p>
! 172: Dale added ELF binary support, and then work with Per Fogelstrom
! 173: continued on general driver support for the next few releases.
! 174: Support was added for OpenFirmware, VI Power4e boards, MCG Powerstack
! 175: machines, DEC 21040, VGA terminal support, and so on.
! 176:
! 177: <p>
! 178: In 1998, the focus shifted towards the Apple machines, and Dale Rahn
! 179: started work to make the range of iMacs and PowerMacs work with this port.
! 180: Due to this, official powerpc releases were not made for the 2.6 and 2.7
! 181: releases as work continued. A number of compiler loader issues were resolved,
! 182: iMac driver support was added, and compatibility with older systems
! 183: was withdrawn to fully concentrate on the Apple machines.
! 184:
! 185: <p>
! 186: OpenBSD/powerpc 2.8 supported Apple hardware.
! 187:
! 188: <p>
! 189: For 2.9, powerpc has moved to UVM, this change has fixed the
! 190: corrupted shared library "pmap" bug that was rather pervasive for 2.8.
! 191:
! 192: <p>
! 193:
! 194: <h3><font color="#0000e0">Known Problems</font></h3>
! 195: The adb keyboard driver, on the iBook and Titanium Powerbook G4,
! 196: has problems such that some keystrokes can cause crashes. This
! 197: problem is mostly contained to multiple keypresses involving the
! 198: <code>Fn</code> key. Also note that <CTRL><CMD><POWER> will reset
! 199: the machine.
! 200: <p>
! 201: USB Hot-Plug detection problems exist on many of the newer systems.
! 202: This problem only exists with the root hub on systems which have only
! 203: one port per root hub, G4 tower systems, PowerBook G4,
