1.1 deraadt 19:
1.3 fn 20: <p>
1.11 deraadt 21: This is a rather new port. It supports some types of machines with
22: PowerPC processors in them -- <strong>but not all</strong>. Even though
1.17 todd 23: there are standards committees trying to resolve the problem, there are
1.11 deraadt 24: significant differences between various PowerPC computers, even when made
25: by the same vendor! This port will run on some machines, but not on others.
26: Check the list below.
1.12 deraadt 27:
28: <p>
29: To work, a machine MUST have some variety of OpenBoot firmware!
1.11 deraadt 30: <p>
31:
32: As such, this is still rather preliminary and should not be considered
1.12 deraadt 33: finished. However, if you have PowerPC hardware we would like to know
1.11 deraadt 34: if it at least boots the install floppy.
35:
36: <p>
37: The following processors are supported: 603, 603e, 604, 604ev.
1.1 deraadt 38:
39: <p>
1.11 deraadt 40: The port does not yet use real device drivers. It uses OpenFirmware
41: for all device driver needs: console, disk, ethernet. It can be
42: installed from floppy and network or cdrom. Netboot and netroot
43: support exists, but is untested.

1.14 deraadt 76: <li>IBM machines.
1.11 deraadt 77: <li>PPCP class machines.
1.13 deraadt 78: <li>Apple PowerMac systems with a 601 processor or lack OpenFirmware
79: will never work.
1.11 deraadt 80: <li>Apple PowerMac systems with at least a 603 processor and OpenFirmware.
81: The Apple implementation of OpenFirmware does not support loading of ELF
82: executables (like the boot-blocks for this port). This needs a workaround.

86: <h3><strong>History:</strong></h3>
87:
88: <p>
89: The powerpc specific portions of the kernel came from the NetBSD port
90: by Wolfgang Solfrank. The userland and build tools came from an
1.17 todd 91: independent and incomplete port by Dale Rahn. Hopefully pieces
1.8 rahnds 92: from that other port will be merged, device driver support for
93: interrupts and some real driver support.
94: The conversion to the Wolfgang port was done because it was running
95: multiuser and the other port was still single user out of memory ramdisk
96: (no fully working device drivers).
