  49. Say Y to support the Acorn Archimedes.
  50. The Acorn Archimedes was an personal computer based on an 8MHz ARM2
  51. processor, released in 1987. It supported up to 16MB of RAM in
  52. later models and floppy, harddisc, ethernet etc.
  53. config ARCH_A5K

  56. Say Y here to to support the Acorn A5000.
  57. Linux can support the
  58. internal IDE disk and CD-ROM interface, serial and parallel port,
  59. and the floppy drive. Note that on some A5000s the floppy is
  60. plugged into the wrong socket on the motherboard.
  61. config PAGESIZE_16
  62. bool "2MB physical memory (broken)"
  63. help
  64. Say Y here if your Archimedes or A5000 system has only 2MB of
  65. memory, otherwise say N. The resulting kernel will not run on a
  66. machine with 4MB of memory.

  102. ---help---
  103. Say Y to include the NWFPE floating point emulator in the kernel.
  104. This is necessary to run most binaries. Linux does not currently
  105. support floating point hardware so you need to say Y here even if
  106. your machine has an FPA or floating point co-processor podule.
  107. It is also possible to say M to build the emulator as a module
  108. (nwfpe) or indeed to leave it out altogether. However, unless you
  109. know what you are doing this can easily render your machine
  110. unbootable. Saying Y is the safe option.
  111. You may say N here if you are going to load the Acorn FPEmulator
  112. early in the bootup.

  114. config PREEMPT
  115. bool "Preemptible Kernel (EXPERIMENTAL)"
  116. depends on CPU_32 && EXPERIMENTAL
  117. help
  118. This option reduces the latency of the kernel when reacting to
  119. real-time or interactive events by allowing a low priority process to
  120. be preempted even if it is in kernel mode executing a system call.
  121. This allows applications to run more reliably even when the system is
  122. under load.
  123. Say Y here if you are building a kernel for a desktop, embedded
  124. or real-time system. Say N if you are unsure.
  125. config ARTHUR
  126. tristate "RISC OS personality"
  127. depends on CPU_32
  128. help
  129. Say Y here to include the kernel code necessary if you want to run
  130. Acorn RISC OS/Arthur binaries under Linux. This code is still very
  131. experimental; if this sounds frightening, say N and sleep in peace.
  132. You can also say M here to compile this support as a module (which
  133. will be called arthur).
  134. config CMDLINE
  135. string "Default kernel command string"
  136. default ""
  137. help
  138. On some architectures (EBSA110 and CATS), there is currently no way
  139. for the boot loader to pass arguments to the kernel. For these
  140. architectures, you should supply some command-line options at build
  141. time by entering them here. As a minimum, you should specify the
  142. memory size and the root device (e.g., mem=64M root=/dev/nfs).
