In order to test EFI BIOS + u-boot payload, I download the EFI 
BIOS(efi-bios.tar.bz2)    from http://wiki.qemu.org/Testing

Here is what I'm trying:

address@hidden:/opt/qemu-test/efi-bios$ ls
bios.bin  efi.disk  README
address@hidden:/opt/qemu-test/efi-bios$ qemu-system-i386 -bios ./bios.bin -hda 
WARNING: Image format was not specified for './efi.disk' and probing guessed 
         Automatically detecting the format is dangerous for raw images, write 
operations on block 0 will be restricted.
         Specify the 'raw' format explicitly to remove the restrictions.

At the same time, the graphic console shows nothing.

My OS is Ubuntu 16.04 and QEMU emulator version is 2.5.0.

 Can anyboad show me the mistake? And how can I use EFI BIOS to boot a u-boot 
payload in qemu emulator?

Best Regards!
