To work, a machine MUST have some variety of OpenBoot firmware!

The processor support is quite stable at this point.

Driver support is currently somewhat limited, due to most PCI devices

only having been tested on little-endian machines. Additional device

support for Macintosh hardware systems is under development any

programming information for any recent Mac hardware would improve

this situation.

As such, this is still rather preliminary and should not be considered

finished.

The port is still not fully stable, but is now running well enough that

is is reasonable to do system development.

Hopefully, all stablity problem will be worked on and this will

become a reasonably useable port.

However, if you have PowerPC hardware we would like to know

if it at least boots the install floppy.

The following processors are supported: 603, 603e, 604, 604ev.

The following processors are supported: 603, 603e, 604, 604ev, 750.

The port does not yet use real device drivers. It uses OpenFirmware

<li>PPCP class machines.

<li>Apple PowerMac systems with a 601 processor or lack OpenFirmware

will never work.

<li>Apple PowerMac systems with at least a 603 processor and OpenFirmware.

<li>The Apple implementation of OpenFirmware does not support loading of ELF

The Apple implementation of OpenFirmware does not support loading of ELF

executables (like the boot-blocks for this port). This needs a workaround.

added, vga cannot be used as console yet, but can be used as a terminal.

No X servers are supported, but the mechanism to access vga via mmap exists.

For 2.5 support continued at the previous level as 2.4.

For 2.6 support an offical release was not made for the powerpc port.

Work on the iMac had started and compiler loader issues had not been

resolved which prevented the system from building out of the tree.

Post 2.6, iMac support has been added, further development is underway

to support the imac devices better and add support for other systems.

Initally with the imac driver support, compatibility with older

systems was lost. This is primarily due to a lack of testing, these

systems will be supported once the system changes are backported.
