Thanks to new kernel images provided by G. Paubert in his site I could obtain some new results (not a success but at least this time the boot is going a bit further). The board has no drive, so I tried two versions of the kernel image: the initrd and the nfsroot, (this last try was to see if something different happens, becauase I do not have a NFS root tree for the PPC). When I boot the zImage.initrd-2.2.4 kernel I get these messages: ------ CLIP HERE ------ Network Booting from: DEC21143, Controller 0, Device 0 Device Name: /pci@80000000/pci1011,19@e,0:0,0 Loading: zimage Client IP Address = 192.84.146.131 Server IP Address = 192.84.146.24 Gateway IP Address = 0.0.0.0 Subnet IP Address Mask = 255.255.255.0 Boot File Name = zimage Argument File Name = Network Boot File load in progress...

My questions are: I have to give some parameter at the boot prompt? And the ram disk image that the README said to be inside the file initrd.gz is still inside the kernel image or it must be loade from this file? It seems quite strange to me also the message: OpenPIC Version ? (2 CPUs and 17 IRQ sources) at d1000000 Why 2 CPU?

I exported an empty /home/ppc directory on the same PC that I used as tftp server, but how the board can recognize just this directory? And what files I have to put in this directory?
