57:
58: <p>
59: The OpenBSD/macppc port started as OpenBSD/powerpc, and was initially
60: focused on Motorola computers with OpenFirmware, and VI Power4e boards.
61: This port was eventually thrown away after OpenBSD 2.5 was released.
62: As a result there was no OpenBSD/powerpc port for the 2.6 and 2.7 releases.
63: In the meantime, a new port was started, focusing on Apple hardware, and
64: based on code from NetBSD/macppc, and after a lot of work from Dale Rahn,
65: OpenBSD 2.8 was released with a powerpc port.
66: As work on the port continued, it was renamed to OpenBSD/macppc for 3.0.

451: <h3><font color="#0000e0">Boot device considerations:</font></h3>
452: <p>
453: Modern MacPPC systems have two IDE interfaces (called Ultra and IDE), each of
454: which can have two devices on them (ultra0, ultra1, ide0, ide1).
455: When multiple drives are present in the system, there are limitations
456: of which drives can be configured as the OpenBSD root drive.
457: Invalid configurations will not be able to properly
458: detect which drive is the root drive, so any attempt will either
459: prompt for a root drive or fail.
460:
461: <ul>
462: <li><tt>ultra0</tt> is always a valid root drive.
463: <li><tt>ultra1</tt> is valid as a root disk, as long as <tt>ultra0</tt>
464: is a hard drive, not a non-hard disk ATAPI device).
465: <li><tt>ide1</tt> (Zip drive bay) is valid as a root disk if no hard drive is
466: located at <tt>ultra1</tt>,
467: <li><tt>ide0</tt> (cdrom) is valid as a root drive <b>only</b> if no hard
468: drives are connected to the Ultra bus.

476: <li>Laptop systems may power off within 2-5 minutes if the lid is closed

478: <li>Older iMacs can have a problem with the USB keyboard driver where
479: the first key pressed after boot will repeat endlessly. The workaround
480: is to press <SHIFT> first or to disconnect and reconnect the USB mouse
