Are you sure the machine in question actually is a PowerPC system as opposed to a POWER architecture RS/6000. LinuxPPC will not run on POWER architecture as LinuxPPC uses PowerPC instructions and memory management is different. The pre-PREP / pre-CHRP RS/6000 loaders are extremely simplistic, but I do not know the details. If it understands XCOFF, then it might look at the entry point for the "application" in the header to know the starting address. David [[ This message was sent via the linuxppc-dev mailing list.
