-PowerPC-based Macintosh systems are divided into "Old World" and "New World" -systems, the difference being -the design -of the system ROM. Only "New World" machines are supported. -Known compatible systems include the following: +OpenBSD/macppc runs on the PowerPC-based Macintosh systems from the +``New World'' family, i.e. all Apple computers from the iMac to current +models. +
+ ++A mailinglist dedicated to the OpenBSD/macppc port is available at +ppc@openbsd.org. +To join the OpenBSD/macppc mailing list, send a message body of "subscribe +ppc" to +majordomo@openbsd.org. +Please be sure to check our mailing list policy before +subscribing. +
+ ++The current port maintainer is Dale Rahn +(drahn@openbsd.org). +

+The OpenBSD/macppc port started as OpenBSD/powerpc, and was initially +focused on Motorola computers with OpenFirmware, and VI Power4e boards. +This port was eventually thrown away after OpenBSD 2.5 was released. +As a result there was no OpenBSD/powerpc port for the 2.6 and 2.7 releases. +In the meantime, a new port was started, focusing on Apple hardware, and +based on code from NetBSD/macppc, and after a lot of work from Dale Rahn, +OpenBSD 2.8 was released with a powerpc port. +As work on the port continued, it was renamed to OpenBSD/macppc for 3.0. +
+ ++Currently, all the hardware listed in the +supported hardware list section below boots +multi-user, supports most, if not all, of the on-board devices, and is +generally useable. +
+ + ++The X-Window system is supported on all MacPPC systems, however +only the ATI graphics adapters are supported by an accelerated +X server at the current time. +The nVidia accelerated X server does not currently work, however nVidia +(and ATI) cards can be used by X in framebuffer (unaccelerated) mode, +at the boot resolution and color depth using the wsfb driver (installed by +default). +
+ ++Directions on enabling the accelerated X server can be found +in the /usr/X11R6/README file on the installed system. +

+The last supported OpenBSD/macppc release is +OpenBSD 3.2. +Here are the + +OpenBSD/macppc 3.2 installation instructions +. +
+ ++Snapshots are made available from time to time, in +this location +as well as in a few +mirrors. +Here are the + +OpenBSD/macppc snapshot installation instructions + as well. +
+ ++There are several installation media provided: +
+ With the OpenBSD CD inserted in the cdrom drive, powering the machine on + while leaving the ``C'' key pressed will bootstrap the installation + procedure. + Alternatively, the CD can be booted at the OpenFirmware prompt, with +
+ boot cd:,ofwboot 3.2/macppc/bsd.rd ++
+ If the system disk is shared with MacOS, the ofwboot boot loader + and the bsd.rd installation media can be copied to the first HFS + or HFS+ partition. + Then the installation procedure can be booted at the OpenFirmware prompt, + with +
+ boot hd:,ofwboot bsd.rd ++
