Hi Peter,
 
Yes I have turned on resierfs and ext2 too because /boot is and ext2 partition. From your description it looks like the AUTOBOOT options are good but not sure why it reports of Unsupported image format. Let me first get rid of GRUB. Do yout know if FILO works for all versions of GRUB boot loaders or there are some specific boot loaders that it supports.
 
Regards,
Phani

As far as I know these two are mutually exclusive. If using the grub
compatibility stuff in FILO then AUTOBOOT_FILE will never be used.

I don't like grub and thus always stick to only using AUTOBOOT_FILE.

In your case the line looks fine if the kernel is stored in
/boot/vmlinuz, if it's /vmlinuz then change to hda3 instead of hda1
in the first argument.

Oh, and make sure you build FILO with reiserfs support if the kernel
is on your root partition.
