  68           Say Y to support the Acorn Archimedes.

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

  89           machine with 4MB of memory.

 129         ---help---
 130           Say Y to include the NWFPE floating point emulator in the kernel.
 131           This is necessary to run most binaries. Linux does not currently
 132           support floating point hardware so you need to say Y here even if
 133           your machine has an FPA or floating point co-processor podule.
 134
 135           It is also possible to say M to build the emulator as a module
 136           (nwfpe) or indeed to leave it out altogether. However, unless you
 137           know what you are doing this can easily render your machine
 138           unbootable. Saying Y is the safe option.
 139
 140           You may say N here if you are going to load the Acorn FPEmulator
 141           early in the bootup.

 146         bool "Preemptible Kernel (EXPERIMENTAL)"
 147         depends on CPU_32 && EXPERIMENTAL
 148         help
 149           This option reduces the latency of the kernel when reacting to
 150           real-time or interactive events by allowing a low priority process to
 151           be preempted even if it is in kernel mode executing a system call.
 152           This allows applications to run more reliably even when the system is
 153           under load.
 154
 155           Say Y here if you are building a kernel for a desktop, embedded
 156           or real-time system.  Say N if you are unsure.

 161         help
 162           Say Y here to include the kernel code necessary if you want to run
 163           Acorn RISC OS/Arthur binaries under Linux. This code is still very
 164           experimental; if this sounds frightening, say N and sleep in peace.
 165           You can also say M here to compile this support as a module (which
 166           will be called arthur).
 167
 168 config CMDLINE
 169         string "Default kernel command string"
 170         default ""
 171         help
 172           On some architectures (EBSA110 and CATS), there is currently no way
 173           for the boot loader to pass arguments to the kernel. For these
 174           architectures, you should supply some command-line options at build
 175           time by entering them here. As a minimum, you should specify the
 176           memory size and the root device (e.g., mem=64M root=/dev/nfs).
