! 62:
! 63: <p>
! 64: The OpenBSD/macppc port started as OpenBSD/powerpc, and was initially
! 65: focused on Motorola computers with OpenFirmware, and VI Power4e boards.
! 66: This port was eventually thrown away after OpenBSD 2.5 was released.
! 67: As a result there was no OpenBSD/powerpc port for the 2.6 and 2.7 releases.
! 68: In the meantime, a new port was started, focusing on Apple hardware, and
! 69: based on code from NetBSD/macppc, and after a lot of work from Dale Rahn,
! 70: OpenBSD 2.8 was released with a powerpc port.
! 71: As work on the port continued, it was renamed to OpenBSD/macppc for 3.0.

! 79: Currently, all the hardware listed in the
! 80: <a href="#hardware">supported hardware list</a> section below boots

! 87: The X-Window system is supported on all MacPPC systems, however
! 88: only the ATI graphics adapters are supported by an <i>accelerated</i>
! 89: X server at the current time.
! 90: The nVidia accelerated X server does not currently work, however nVidia
! 91: (and ATI) cards can be used by X in framebuffer (unaccelerated) mode,
! 92: at the boot resolution and color depth using the wsfb driver (installed by
! 93: default).
! 94: </p>
! 95:

397: <li>Serial Ports: While the modern PowerMacintosh series has no external
398: standard serial ports, many have an on-board modem which can be
399: removed and replaced with an adapter (several manufacturers of these exist)
400: which will produce a standard (and supported) serial port.

402: on the firewire bus, yet.
403: <li>Backlight on lcd devices can be controlled thru the brightness control
404: keys on ADB (laptop) keyboards, or thru 'wsconsctl -w display.brightness=xx'
405: (0 - 100) and 'wsconsctl -w display.backlight=xx' (0 or 100)

1.13 nick 419: <li>Older OpenFirmware machines are not currently supported.
420: This is mostly due to lack of developer resources and limited

423: the serial port the modem is attached to is supported, but the modem
424: itself is not supported.
425: <li>Newer PowerBooks have an internal modem attached as a USB device, these
