  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.

  74. Say Y here if you intend to execute your compressed kernel image (zImage)
  75. directly from ROM or flash. If unsure, say N.

  87. help
  88. The base address of 64KiB of read/write memory, which must be available
  89. while the decompressor is running. Unless you have special requirements,
  90. you should not change this value.

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

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