Ah, okay.

Should I be using objcopy to cut these sections out of my SOM executable
and into the LIF image?

Two other problems I have:

1. The kernel doesn't build yet, it fails to link and dies with:


ld -e stext arch/parisc/kernel/head.o arch/parisc/kernel/init_task.o
init/main.o init/version.o \
        arch/parisc/kernel/kernel.o arch/parisc/mm/mm.o kernel/kernel.o
mm/mm.o fs/fs.o ipc/ipc.o \
        fs/filesystems.a \
        net/network.a \
        drivers/block/block.a drivers/char/char.a  drivers/net/net.a \
        /usr/src/linux/arch/parisc/lib/lib.a /usr/src/linux/lib/lib.a
/usr/src/linux/arch/parisc/lib/lib.a \
        -o vmlinux
ld: Unsatisfied symbols:
   swapper_pg_dir (data)
   _stext (data)

I haven't yet figured out how to solve this.

2. The bootloader within the kernel tries to load the vmlinux into
memory, but dies by returning -6 at the P0_BOOTDEV_iodc_io() call within
bootdev_sread() in rom _interface.c.  I should be able to figure out
what's going on here...
