How to boot from yaboot 'boot' prompt

Hi all,

I'm using an IBM p-series machine. Because of yaboot configuration
file error, the machine can not boot. Now I only can get a "boot:'
prompt. I know where the kernel and initrd image locate.

I tried as following:

boot:/pci at 8000000f8000000/pci at 1/pci1014,028C at 1/scsi at 0/sd at 1,0:2,/vmlinuz-2.6.16-1.2289_FC6

This can load the kernel but can not identify /dev/sda3. I think this
is due to lack of some drivers. So I append
'initrd=/initrd-2.6.16-1.2289_FC6.img' after the command line. But it
doesn't work either. Kernel doesn't load ramdisk at all.

How do I load them from the yaboot prompt ?
