120	  On some platforms, there is currently no way for the boot loader
121	  to pass arguments to the kernel. For these, you should supply some
122	  command-line options at build time by entering them here.  At a
123	  minimum, you should specify the memory size and the root device
124	  (e.g., mem=64M root=/dev/nfs).
