[coreboot] Audio mute problem

Hello,
The audio on the RM4100 is muted by default. I know the assembly code  
to unmute it but I am not so good with the assembly, could someone  
translate this for me into human???

seg000:00000000 mov edx, 84Dh
seg000:00000005 mov eax, 0C0h ; '+'
seg000:0000000A out dx, al

Thanks - Joe
