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