I would like to offer the opportunity to give Haiku more visibility in today computing market.
I am looking for someone to port Haiku to this PowerPC machine:

And I'm willing to pay for such job! :-)

I know that some work have been done to port Haiku to PPC MACs so I hope porting to this motherboard will not be too difficult.

I'm not taking either, though I'm one of those occasionally working on the ppc Mac port. I guess that anyone considering your offer will need a little more information on what's involved.

For instance, am I understanding correctly that the board does not feature an IEEE 1275 Open Firmware [1]? It mentions UBoot [2] instead. So it needs a completely new boot loader, duplicating the existing unfinished efforts?

Is the 440ep a single-core CPU? I saw an 8-core e500ec [3] at Embedded World and thought it would be interesting, but the pricing made that much less so. ;)

Seriously, the problems we're facing are occasional kernel load failures [4] as well as MMU problems at various boot stages [5, 6]. And QEMU w/OpenBIOS has been unable to emulate it. Nor is there any graphics support yet that I'm aware of.

But I don't want to discourage anyone, these challenges are definitely solvable since Linux runs on both Macs and 440 boards. :) There's even a KVM for 440 [7], so it may be virtualizable.
