! 120: <a name="#unsup"><h3><font color=#0000e0>Unsupported Hardware:</font></h3></a>
! 121: <ul>
! 122: <li>
! 123: Support for older PREP style machines has been removed; lack of
! 124: availability of the hardware and relatively slow speed compared to more
! 125: recent machines has contributed to this decision.
! 126: <li>
! 127: Apple PowerMac systems with a 601 processor or lack OpenFirmware
! 128: will likely never be supported.
! 129: <li>
! 130: At the current time, older OpenFirmware machines are not supported.
! 131: This is mostly due to lack of developer resources to work on the support
! 132: in addition to limited availability of hardware.
! 133: <li>On the device side, the following are recognized, but not supported:
! 134: <ul>
! 135: <li>Texas Instruments TSB12LV23 FireWire
! 136: </ul>
! 137: </ul>
! 138:
! 139: <h3><font color="#0000e0">Shared HFS disks:</font></h3>
! 140: <p>
! 141: It is possible to share a disk between MacOS (OS X?) and OpenBSD.
! 142: MacOS must be installed first, and an Unused partition or other free
! 143: partition can then be used to install OpenBSD.
! 144: If a shared disk is to be used and be bootable, the bootloader "ofwboot"
! 145: must be copied onto the first HFS partition.
! 146: It is unknown if Openfirmware can load the OpenBSD bootloader from the
! 147: MacOS X FFS partition.
! 148: See INSTALL.powerpc for more details on how to install a shared disk.
! 149:
! 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.
! 175:
! 176: <hr>
! 177: <p>If you are looking for to test new pre-release features, you can
! 178: try one of the snapshots.
! 179: For the powerpc architecture, <a href="ftp://ftp.openbsd.org/pub/OpenBSD/snapshots/powerpc">snapshots</a> are made available from time to time.
! 180:
! 181: <h3><font color="#0000e0">History:</font></h3>
! 182: <p>
! 183: The powerpc port was first imported into OpenBSD at the end of 1996.
! 184: Portions of the kernel came from the NetBSD/macppc port, and the
! 185: userland and build pieces came from
! 186: <a href="mailto:drahn@openbsd.org">Dale Rahn</a>.
! 187:
! 188: <p>
! 189: Dale added ELF binary support, and then work with Per Fogelstrom
! 190: continued on general driver support for the next few releases.
! 191: Support was added for OpenFirmware, VI Power4e boards, MCG Powerstack
! 192: machines, DEC 21040, VGA terminal support, and so on.
! 193:
! 194: <p>
! 195: In 1998, the focus shifted towards the Apple machines, and Dale Rahn
! 196: started work to make the range of iMacs and PowerMacs work with this port.
! 197: Due to this, official powerpc releases were not made for the 2.6 and 2.7
! 198: releases as work continued. A number of compiler loader issues were resolved,
! 199: iMac driver support was added, and compatibility with older systems
! 200: was withdrawn to fully concentrate on the Apple machines.
! 201:
! 202: <p>
! 203: OpenBSD/powerpc 2.8 supported Apple hardware.
! 204:
! 205: <p>
! 206: For 2.9, powerpc has moved to UVM, this change has fixed the
! 207: corrupted shared library "pmap" bug that was rather pervasive for 2.8.
! 208:
! 209: <p>
! 210:
! 211: <h3><font color="#0000e0">Known Problems</font></h3>
! 212: The adb keyboard driver, on the iBook and Titanium Powerbook G4,
! 213: has problems such that some keystrokes can cause crashes. This
! 214: problem is mostly constrained to multiple keypresses involving the
! 215: <code>Fn</code> key. Also note that <CTRL><CMD><POWER> will
! 216: reset the machine.
! 217: <p>
! 218: USB Hot-Plug detection problems exist on many of the newer systems.
! 219: This problem only exists with the root hub on systems which have only
! 220: one port per root hub, G4 tower systems, PowerBook G4, newer iMacs.
! 221: These systems configure with both ohci0 and ohci1.
