[FILO] prompt doesn't work...

Hi, long time no see.

I did build a filo with default config. ( make  & make )  
serial debug message is like below. But I can't type any command.
VGA Console prompt has also the same problem.

My Board is likely to EPIA 5000.

Does FILO use only PS/2 keyboard as Input Device Driver?

FILO !!! Good Idea .

Thanks ... 
from newbie.
