mkelfImage is mainly used in two cases:

1. tiny kernel and tiny initrd in flash chip
2. booting from network with etherboot/gpxe

Since you are using FILO, you do not need to create an elf image,
FILO is able to load both kernel and initrd from the storage media
directly.

The image that is supposed to be flashed is probably called
linuxbios.rom and is generated after you have run buildtarget
followed by make in the appropriate directory below
LinuxBIOSv2/targets/

Hope this helps.
