- On some architectures (EBSA110 and CATS), there is currently no way
- for the boot loader to pass arguments to the kernel. For these
- architectures, you should supply some command-line options at build
- time by entering them here. As a minimum, you should specify the
- memory size and the root device (e.g., mem=64M root=/dev/nfs).
