Wrong BIOS version updated

Hi, 

I had update Latte Panda Alpha (M3-8100Y, KR-310) and try to update BIOS to get Auto Power On.

But i was update wrong version which is for KR-300. after updated BIOS, Alpha is no turn on with only turn on RED/BLUE led on the board.

So i am wondering how can i refresh BIOS as default..

I am waiting for your support.

Thanks

Best regards.
