Guys, I don't know what your plans with the PPC port are, but if you intend to 
go 
further than fixing a few hardware or OF specific bugs and the regressions that 
cropped up since I left it alone, you really need to learn to be a bit more 
self-sufficient. The PPC port is really unfinished and if you plan to get it 
actually 
working, you'll have to seriously dig into at least the PPC architecture 
documentation 
and the kernel source. Probably as well into boot loader, libroot, runtime 
loader, and 
some part of gcc/binutils. So answering simple questions like the one above you 
should 
really be able to do yourself in a few minutes by employing basic tools like 
find, svn 
log, google, and looking into the source.

Anway, "remote disk" is a simple hown-brewn protocol for serving a disk image 
over 
UDP. The intended application is network boot. I used it when working on the 
PPC port 
to get reasonable turn-around times. If you have a working PPC emulator it's 
probably 
less interesting, but if you want to work with real hardware, a two machine 
setup with 
netboot is really the way to go. As for how to use it, you have to run 
remote_disk_server on your development machine. I believe the PPC OF boot 
loader 
automatically picks it up, when you load the boot loader via TFTP. I don't 
recall any 
further details, but it shouldn't be hard to extract more info from the boot 
loader, 
if necessary.

CU, Ingo
