FILO finds your CF.

But the IDE controller and CF card is not found by the kernel. It
does not even look for them. Please make sure you use a kernel which
has built-in support for whatever hardware you need in order to boot
your system, unless you also specify a ramdisk that FILO should load.


Starting my systems with original BIOS installed OS (zenwalk) starts without 
any problems. But just changing BIOS to coreboot posted problems raise. So I 
don't think this could be a problem on used kernel.

Because of changing BIOS I think something in coreboot is different to 
original BIOS. But I don't know what this could be. So I hope some here could 
give me a hint.
