  61. Say Y to support the Acorn Archimedes.
  62. The Acorn Archimedes was an personal computer based on an 8MHz ARM2
  63. processor, released in 1987. It supported up to 16MB of RAM in
  64. later models and floppy, harddisc, ethernet etc.

  69. Say Y here to support the Acorn A5000.
  70. Linux can support the
  71. internal IDE disk and CD-ROM interface, serial and parallel port,
  72. and the floppy drive. Note that on some A5000s the floppy is
  73. plugged into the wrong socket on the motherboard.
  74. config PAGESIZE_16
  75. bool "2MB physical memory (broken)"
  76. help
  77. Say Y here if your Archimedes or A5000 system has only 2MB of
  78. memory, otherwise say N. The resulting kernel will not run on a
  79. machine with 4MB of memory.

  116. ---help---
  117. Say Y to include the NWFPE floating point emulator in the kernel.
  118. This is necessary to run most binaries. Linux does not currently
  119. support floating point hardware so you need to say Y here even if
  120. your machine has an FPA or floating point co-processor module.
  121. It is also possible to say M to build the emulator as a module
  122. (nwfpe) or indeed to leave it out altogether. However, unless you
  123. know what you are doing this can easily render your machine
  124. unbootable. Saying Y is the safe option.
  125. You may say N here if you are going to load the Acorn FPEmulator
  126. early in the bootup.

  128. config PREEMPT
  129. bool "Preemptible Kernel (EXPERIMENTAL)"
  130. depends on CPU_32 && EXPERIMENTAL
  131. help
  132. This option reduces the latency of the kernel when reacting to
  133. real-time or interactive events by allowing a low priority process to
  134. be preempted even if it is in kernel mode executing a system call.
  135. This allows applications to run more reliably even when the system is
  136. under load.
  137. Say Y here if you are building a kernel for a desktop, embedded
  138. or real-time system. Say N if you are unsure.
  139. config ARTHUR

  141. depends on CPU_32
  142. help
  143. Say Y here to include the kernel code necessary if you want to run
  144. Acorn RISC OS/Arthur binaries under Linux. This code is still very
  145. experimental; if this sounds frightening, say N and sleep in peace.
  146. You can also say M here to compile this support as a module (which
  147. will be called arthur).
  148. config CMDLINE
  149. string "Default kernel command string"
  150. default ""
  151. help
  152. On some architectures (EBSA110 and CATS), there is currently no way
  153. for the boot loader to pass arguments to the kernel. For these
  154. architectures, you should supply some command-line options at build
  155. time by entering them here. As a minimum, you should specify the
  156. memory size and the root device (e.g., mem=64M root=/dev/nfs).
