If FILO is a payload in flash, then you need to set CONFIG_ROM_STREAM=1 
and CONFIG_ROM_STREAM_START to the address you want to start looking 
for the payload ELF header (usually just after the LinuxBIOS image). 
CONFIG_IDE_STREAM is used to load a payload (such as FILO) from an 
attached IDE device. This is useful if the flash is not large enough to 
hold LinuxBIOS+payload, but is probably not what you are looking for. 
Sorry for the confusion.
