Thanks to the both of you. The objdump command worked.
I tried the objcopy before I emailed and converted the binary file to an
ELF format but for some reason the architecture would not get written to
the created elf file:
PPC_440-bojcopy -I binary -O elf32-powerpc -B powerpc file file.elf
trying to do an "objdump -f" showed that there was no architecture
information copied over. Trying to disassemble this resulted in an error
saying the architecture was unknown. Probably this was a problem with my
tools so I won't worry about it. And it would have to go on another
thread anyhow.
Thanks again.
Fahd

Alternatively, use objcopy to convert the file into an ELF image.
