<h3><font color="#0000e0">Multiboot/Shared HFS disks:</font></h3> |
| |
<p> |
| |
Multiboot/sharing a disk with OS X/MacOS 9 is possible as long as the |
| |
disk is first partitioned with the MacOS utility. An "Unused" or other |
| |
available partition must be left for OpenBSD's use. |
| |
Since the machines are only able to boot from HFS (not MacOS X UFS) partitions |
| |
the first partition must formated HFS(+), not UFS to be able to boot |
| |
OpenBSD. |
| |
<p> |
| |
See INSTALL.macppc for more details on how to install a shared disk. |
| |
<p> |
| |
Standalone (no MacOS present) installation is also supported. |
| |
|
| |
<h3><font color="#0000e0">Root Drive:</font></h3> |
| <p> |
<p> |
| |
When multiple drives are present in the system, only certain drives |
| |
can be configured as the OpenBSD root drive. |
| |
Any other configurations than those below will not be able to properly |
| |
detect which drive is the root drive, and so any attempt with either |
| |
prompt for a root drive, or fail. |
| |
<p> |
| |
<ul> |
| |
<li><tt>ultra0</tt> is always fine to use as an root drive. |
| |
<li><tt>ultra1</tt> is fine to use as a root disk (as long as <tt>ultra0</tt> |
| |
is a hard drive, not ATAPI). |
| |
<li>If no hard drive is located at <tt>ultra1</tt>, it is possible to use a |
| |
hard drive configured as <tt>ide1</tt> (zip bay) as root drive. |
| |
<li>It is not possible to use <tt>ide0</tt> (CD-ROM) as a root drive unless |
| |
no drives are connected to the Ultra IDE bus. |
| |
</ul> |
| |
|
| |
<h3><font color="#0000e0">X Window System:</font></h3> |
| |
<p> |
| |
XFree86 Version 4.2.0 is supported on all systems. |
| |
Only the ATI graphics adapters are supported with the accelerated X server |
| |
at the current time. |
| |
The Nvidia driver does not currently work. |
| |
It is possible to use X in framebuffer mode with either the nvidia cards |
| |
or ATI at the boot resolution/depth using the wsfb driver. |
| |
<p> |
| |
The wsfb driver (installed by default) will allow either the Nvidia cards |
| |
or the ATI cards to run X in framebuffer mode at the boot resolution/depth. |
| |
The directions on how to enable the accelerated X server is present |
| |
in the <tty>/usr/X11R6/README</tty> file on the installed system. |
| |
<p> |

<h3><font color="#0000e0">Known Problems</font></h3> |
| |
<ul> |
| |
<li>Sleep/suspend is not supported. |
| |
<li>Turning off the backlight/screen blanking is not supported. |
| |
<li>gm0 driver does not support 1000Mb operation, only 10/100Mb. |
| |
<li>Feature that <CTRL><CMD><POWER> on ADB will reset |
| |
the machine. |

</ul> |

| <h3><font color="#0000e0">Shared HFS disks:</font></h3> |
|
| <p> |
|
| It is possible to share a disk between MacOS (OS X?) and OpenBSD. |
|
| MacOS must be installed first, and an Unused partition or other free |
|
| partition can then be used to install OpenBSD. |
|
| If a shared disk is to be used and be bootable, the bootloader "ofwboot" |
|
| must be copied onto the first HFS partition. |
|
| It is unknown if Openfirmware can load the OpenBSD bootloader from the |
|
| MacOS X FFS partition. |
|
| See INSTALL.macppc for more details on how to install a shared disk. |
|
| |
|
| <h3><font color="#0000e0">Root Drive:</font></h3> |
|
| <p> |
|
| With multiple drives installed in the system, only certain drives can |
|
| be configured as an OpenBSD root drive. Any other configurations than |
|
| those below will not be able to properly detect which drive is the root |
|
| drive, and so any attempt with either prompt for a root drive, or fail. |

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

| <h3><font color="#0000e0">History:</font></h3> |
|
| <p> |
<p> |
| The powerpc port was first imported into OpenBSD at the end of 1996. |
|
| Portions of the kernel came from the NetBSD/macppc port, and the |
|
| userland and build pieces came from |
|
| <a href="mailto:drahn@openbsd.org">Dale Rahn</a>. |
|
| |
|
| <p> |
|
| Dale added ELF binary support, and then work with Per Fogelstrom |
|
| continued on general driver support for the next few releases. |
|
| Support was added for OpenFirmware, VI Power4e boards, MCG Powerstack |
|
| machines, DEC 21040, VGA terminal support, and so on. |
|
| |
|
| <p> |
|
| In 1998, the focus shifted towards the Apple machines, and Dale Rahn |
|
| started work to make the range of iMacs and PowerMacs work with this port. |
|
| Due to this, official powerpc releases were not made for the 2.6 and 2.7 |
|
| releases as work continued. A number of compiler loader issues were resolved, |
|
| iMac driver support was added, and compatibility with older systems |
|
| was withdrawn to fully concentrate on the Apple machines. |
|
| |
|
| <p> |
|
| OpenBSD/powerpc 2.8 supported Apple hardware. |
|
| |
|
| <p> |
|
| For 2.9, powerpc has moved to UVM, this change has fixed the |
|
| corrupted shared library "pmap" bug that was rather pervasive for 2.8. |
|
| |
|
| <p> |
|
| For 3.0, the powerpc port has been renamed to macppc. |
|
| |
|
| <p> |
|
| |
|
| <h3><font color="#0000e0">Known Problems</font></h3> |
|
| The adb keyboard driver, on the iBook and Titanium PowerBook G4, |
|
| has problems such that some keystrokes can cause crashes. This |
|
| problem is mostly constrained to multiple keypresses involving the |
|
| <code>Fn</code> key. Also note that <CTRL><CMD><POWER> will |
|
| reset the machine. |
