Thanks both of you peter and brian,

however, the boot protocol document saying "%rsi must hold the base address of the struct boot_params",
it doesn't mention why. Maybe the document needs update to justify the reasons. I wouldn't have known it 
if you didn't tell me, so this shouldn't confuse anyone else.

Thanks 
Khalid Ali
