These are all ELF format kernels, intended to be booted using the 2 stage
NetBSD Bootloader which can lift this kernel off the root filesytem.
Unfortunately the firmware won't boot ELF kernels (unlike some SGI machines)

You can use elf2ecoff on a running NetBSD Mips based platform (mipsco,
sgimips etc), or use the nbmips-elf2ecoff if you build a toolchain for any
mips based target.
Once you have converted the file to ECOFF format, you will be able to
network boot it.

You can do that, but I doubt whether this is enough space for a full
kernel, you need to install the 2 stage bootloader instead.

PS.  Sounds like it's time to build a new snapshot.  I need to integrate
installboot into the toolchain version (so it will cross compile) which
would allow an installkernel to be built again....
