  82           The Acorn Archimedes was an personal computer based on an 8MHz ARM2
  83           processor, released in 1987.  It supported up to 16MB of RAM in

 147         ---help---
 148           Say Y to include the NWFPE floating point emulator in the kernel.
 149           This is necessary to run most binaries. Linux does not currently
 150           support floating point hardware so you need to say Y here even if
 151           your machine has an FPA or floating point co-processor module.
 152
 153           It is also possible to say M to build the emulator as a module
 154           (nwfpe) or indeed to leave it out altogether. However, unless you
 155           know what you are doing this can easily render your machine
 156           unbootable. Saying Y is the safe option.
 157
 158           You may say N here if you are going to load the Acorn FPEmulator
 159           early in the bootup.

 166         help
 167           This option reduces the latency of the kernel when reacting to
 168           real-time or interactive events by allowing a low priority process to
 169           be preempted even if it is in kernel mode executing a system call.
 170           This allows applications to run more reliably even when the system is
 171           under load.
 172
 173           Say Y here if you are building a kernel for a desktop, embedded
 174           or real-time system.  Say N if you are unsure.

 179         help
 180           Say Y here to include the kernel code necessary if you want to run
 181           Acorn RISC OS/Arthur binaries under Linux. This code is still very
 182           experimental; if this sounds frightening, say N and sleep in peace.
 183           You can also say M here to compile this support as a module (which
 184           will be called arthur).

 186 config CMDLINE
 187         string "Default kernel command string"
 188         default ""
 189         help
 190           On some architectures (EBSA110 and CATS), there is currently no way
 191           for the boot loader to pass arguments to the kernel. For these
 192           architectures, you should supply some command-line options at build
 193           time by entering them here. As a minimum, you should specify the
 194           memory size and the root device (e.g., mem=64M root=/dev/nfs).
