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

 139         ---help---
 140           Say Y to include the NWFPE floating point emulator in the kernel.
 141           This is necessary to run most binaries. Linux does not currently
 142           support floating point hardware so you need to say Y here even if
 143           your machine has an FPA or floating point co-processor module.
 144
 145           It is also possible to say M to build the emulator as a module
 146           (nwfpe) or indeed to leave it out altogether. However, unless you
 147           know what you are doing this can easily render your machine
 148           unbootable. Saying Y is the safe option.
 149
 150           You may say N here if you are going to load the Acorn FPEmulator
 151           early in the bootup.

 158         help
 159           This option reduces the latency of the kernel when reacting to
 160           real-time or interactive events by allowing a low priority process to
 161           be preempted even if it is in kernel mode executing a system call.
 162           This allows applications to run more reliably even when the system is
 163           under load.
 164
 165           Say Y here if you are building a kernel for a desktop, embedded
 166           or real-time system.  Say N if you are unsure.

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

 178 config CMDLINE

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